REST API Documentation

API default service port is 6420. However, if running the desktop or standalone releases from the website, the port is randomized by default.

A REST API implemented in Go is available, see Skycoin REST API Client Godoc.

The API has two versions, /api/v1 and /api/v2.

API Version 1

/api/v1 endpoints have no standard format. Most of them accept formdata in POST requests, but a few accept application/json instead. Most of them return JSON but one or two return a plaintext string.

All endpoints will set an appropriate HTTP status code, using 200 for success and codes greater than or equal to 400 for error.

/api/v1 endpoints guarantee backwards compatibility.

API Version 2

Note: API Version 2 is under development, and not stable. The guidelines here are subject to change.

/api/v2 endpoints have a standard format.

All /api/v2 POST endpoints accept only application/json and return application/json.

All /api/v2 GET requires accept data in the query string. In the future we may have choose to have GET requests also accept POST with a JSON body, to support requests with a large query body, such as when requesting data for a large number of addresses or transactions.

/api/v2 responses are always JSON. If there is an error, the JSON object will look like this:

{
    "error": {
        "code": 400,
        "message": "bad arguments",
    }
}

Response data will be included in a "data" field, which will always be a JSON object (not an array).

Some endpoints may return both "error" and "data". This will be noted in the documentation for that endpoint.

All responses will set an appropriate HTTP status code indicating an error, and it will be equal to the value of response["error"]["code"].

Since /api/v2 is still under development, there are no guarantees for backwards compatibility. However, any changes to the API will be recorded in the changelog.

Under some circumstances an error response body may not be valid JSON. Any client consuming the API should accomodate this and conditionally parse JSON for non-200 responses.

API Sets

API endpoints are grouped into "sets" which can be toggled with the command line parameters -enable-api-sets, -disable-api-sets and -enable-all-api-sets.

These API sets are:

• READ - All query-related endpoints, they do not modify the state of the program
• STATUS - A subset of READ, these endpoints report the application, network or blockchain status
• TXN - Enables /api/v1/injectTransaction and /api/v1/resendUnconfirmedTxns without enabling wallet endpoints
• WALLET - These endpoints operate on local wallet files
• PROMETHEUS - This is the /api/v2/metrics method exposing in Prometheus text format the default metrics for Skycoin node application
• NET_CTRL - The /api/v1/network/connection/disconnect method, intended for network administration endpoints
• INSECURE_WALLET_SEED - This is the /api/v1/wallet/seed endpoint, used to decrypt and return the seed from an encrypted wallet. It is only intended for use by the desktop client.
• STORAGE - This is the /api/v2/data endpoint, used to interact with the key-value storage.

Authentication

Authentication can be enabled with the -web-interface-username and -web-interface-password options. The username and password should be provided in an Authorization: Basic header.

Authentication can only be enabled when using HTTPS with -web-interface-https, unless -web-interface-plaintext-auth is enabled.

CSRF

All POST, PUT and DELETE requests require a CSRF token, obtained with a GET /api/v1/csrf call. The token must be placed in the X-CSRF-Token header. A token is only valid for 30 seconds and it is expected that the client obtains a new CSRF token for each request. Requesting a CSRF token invalidates any previous CSRF token.

A request rejected for invalid or expired CSRF will respond with 403 Forbidden - invalid CSRF token as the response body.

Get unspent output set of address or hash

API sets: READ

URI: /api/v1/outputs
Method: GET, POST
Args:
    addrs: address list, joined with ","
    hashes: hash list, joined with ","

Addrs and hashes cannot be combined.

In the response, "head_outputs" are outputs in the current unspent output set, "outgoing_outputs" are head outputs that are being spent by an unconfirmed transaction, and "incoming_outputs" are outputs that will be created by an unconfirmed transaction.

The current head block header is returned as "head".

The POST method can be used if many addresses or hashes need to be queried.

Example:

curl http://127.0.0.1:6420/api/v1/outputs?addrs=6dkVxyKFbFKg9Vdg6HPg1UANLByYRqkrdY

or

curl http://127.0.0.1:6420/api/v1/outputs?hashes=7669ff7350d2c70a88093431a7b30d3e69dda2319dcb048aa80fa0d19e12ebe0

Get unconfirmed transactions of a wallet

API sets: WALLET

URI: /api/v1/wallet/transactions
Method: GET
Args:
    id: Wallet ID
    verbose: [bool] include verbose transaction input data

Returns all unconfirmed transactions for all addresses in a given wallet

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours. The hours are the original hours the output was created with. The calculated hours are based upon the current system time, and are approximately equal to the hours the output would have if it become confirmed immediately.

Create transaction

API sets: WALLET

URI: /api/v1/wallet/transaction
Method: POST
Content-Type: application/json
Args: JSON body, see examples

Creates a transaction, returning the transaction preview and the encoded, serialized transaction. The encoded_transaction can be provided to POST /api/v1/injectTransaction to broadcast it to the network if the transaction is fully signed.

The request body includes:

• An optional change address
• A wallet to spend from with the optional ability to restrict which addresses or which unspent outputs in the wallet to use
• A list of destinations with address and coins specified, as well as optionally specifying hours
• A configuration for how destination hours are distributed, either manual or automatic
• Additional options

change_address is optional. If not provided and the wallet is a deterministic type wallet, then the change address will default to an address from one of the unspent outputs being spent as a transaction input. If the wallet is a bip44 type wallet, then a new, unused change address will be created.

Example request body with manual hours selection type, unencrypted wallet and all wallet addresses may spend:

{
    "hours_selection": {
        "type": "manual"
    },
    "wallet_id": "foo.wlt",
    "change_address": "nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq",
    "to": [{
        "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
        "coins": "1.032",
        "hours": "7"
    }, {
        "address": "7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD",
        "coins": "99.2",
        "hours": "0"
    }],
    "unsigned": false,
    "ignore_unconfirmed": false
}

Example request body with auto hours selection type, encrypted wallet, specified spending addresses:

{
    "hours_selection": {
        "type": "auto",
        "mode": "share",
        "share_factor": "0.5"
    },
    "wallet_id": "foo.wlt",
    "password": "foobar",
    "addresses": ["2iVtHS5ye99Km5PonsB42No3pQRGEURmxyc"],
    "change_address": "nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq",
    "to": [{
        "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
        "coins": "1.032"
    }, {
        "address": "7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD",
        "coins": "99.2"
    }],
    "unsigned": false,
    "ignore_unconfirmed": false
}

Example request body with manual hours selection type, unencrypted wallet and spending specific unspent outputs:

{
    "hours_selection": {
        "type": "manual"
    },
    "wallet_id": "foo.wlt",
    "unspents": ["519c069a0593e179f226e87b528f60aea72826ec7f99d51279dd8854889ed7e2", "4e4e41996297511a40e2ef0046bd6b7118a8362c1f4f09a288c5c3ea2f4dfb85"],
    "change_address": "nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq",
    "to": [{
        "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
        "coins": "1.032",
        "hours": "7"
    }, {
        "address": "7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD",
        "coins": "99.2",
        "hours": "0"
    }],
    "unsigned": false,
    "ignore_unconfirmed": false
}

The hours_selection field has two types: manual or auto.

If manual, all destination hours must be specified.

If auto, the mode field must be set. The only valid value for mode is "share". For the "share" mode, share_factor must also be set. This must be a decimal value greater than or equal to 0 and less than or equal to 1. In the auto share mode, the remaining hours after the fee are shared between the destination addresses as a whole, and the change address. Amongst the destination addresses, the shared hours are distributed proportionally.

When using the auto "share" mode, if there are remaining coin hours as change, but no coins are available as change from the wallet (which are needed to retain the coin hours as change), the share_factor will switch to 1.0 so that extra coin hours are distributed to the outputs instead of being burned as an additional fee. For the manual mode, if there are leftover coin hours but no coins to make change with, the leftover coin hours will be burned in addition to the required fee.

All objects in to must be unique; a single transaction cannot create multiple outputs with the same address, coins and hours.

For example, this is a valid value for to, if hours_selection.type is "manual":

[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "1"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "2"
}]

But this is an invalid value for to, if hours_selection.type is "manual":

[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "1"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "1"
}]

And this is a valid value for to, if hours_selection.type is "auto":

[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.201"
}]

But this is an invalid value for to, if hours_selection.type is "auto":

[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2"
}]

To control which addresses to spend from, specify addresses. A subset of the unspent outputs associated with these addresses will be chosen for spending, based upon an internal selection algorithm.

To control which unspent outputs to spend from, specify unspents. A subset of these unspent outputs will be chosen for spending, based upon an internal selection algorithm.

addresses and unspents cannot be combined.

If neither addresses nor unspents are specified, then all outputs associated with all addresses in the wallet may be chosen from to spend with.

change_address is optional. If set, it is not required to be an address in the wallet. If not set, it will default to one of the addresses associated with the unspent outputs being spent in the transaction.

ignore_unconfirmed is optional and defaults to false. When false, the API will return an error if any of the unspent outputs associated with the wallet addresses or the wallet outputs appear as spent in a transaction in the unconfirmed transaction pool. When true, the API will ignore unspent outputs that appear as spent in a transaction in the unconfirmed transaction pool when building the transaction, but not return an error.

unsigned is optional and defaults to false. When true, the transaction will not be signed by the wallet. An unsigned transaction will be returned. The "txid" value of the "transaction" object will need to be updated after signing the transaction. The unsigned encoded_transaction can be sent to POST /api/v2/wallet/transaction/sign for signing.

Example:

curl -X POST http://127.0.0.1:6420/api/v1/wallet/transaction -H 'content-type: application/json' -d '{
    "hours_selection": {
        "type": "auto",

Sign transaction

API sets: WALLET

URI: /api/v2/wallet/transaction/sign
Method: POST
Content-Type: application/json
Args: JSON body, see examples

Signs an unsigned transaction, returning the transaction with updated signatures and the encoded, serialized transaction. The transaction must spendable to be signed. If the inputs of the transaction are not in the unspent pool, signing fails.

Specific transaction inputs may be signed by specifying sign_indexes, otherwise all transaction inputs will be signed. sign_indexes is an array of positional indexes for the transaction's signature array. Indexes start at 0.

Signing an input that is already signed in the transaction is an error.

The encoded_transaction can be provided to POST /api/v1/injectTransaction to broadcast it to the network, if the transaction is fully signed.

Example:

curl -X POST http://127.0.0.1:6420/api/v2/wallet/transaction/sign -H 'content-type: application/json' -d '{
    "wallet_id": "foo.wlt",

Key-value storage APIs

Endpoints interact with the key-value storage. Each request require the type argument to be passed.

Currently allowed types:

• txid: used for transaction notes
• client: used for generic client data, instead of using e.g. LocalStorage in the browser

Get all storage values

API sets: STORAGE

Method: GET
URI: /api/v2/data
Args:
    type: storage type
    key [string]: key of the specific value to get

If key is passed, only the specific value will be returned from the storage. Otherwise the whole dataset will be returned.

If the key does not exist, a 404 error is returned.

Example:

curl http://127.0.0.1:6420/api/v2/data?type=txid

Result:

{
    "data": {
        "key1": "value",
        "key2": "{\"key\":\"value\"}",
    }
}

Example (key):

curl http://127.0.0.1:6420/api/v2/data?type=txid&key=key1

Result:

{
    "data": "value"
}

Add value to storage

API sets: STORAGE

Method: POST
URI: /api/v2/data
Args: JSON Body, see examples

Example request body:

{
    "type": "txid",
    "key": "key1",
    "val": "val1"
}

Example:

curl -X POST http://127.0.0.1:6420/api/v2/data -H 'Content-Type: application/json' -d '{
    "type": "txid",
    "key": "key1",
    "val": "val1"
}'

Result:

{}

Remove value from storage

API sets: STORAGE

Method: DELETE
URI: /api/v2/data
Args:
    type: storage type
    key: key of the specific value to get

Deletes a value by key. Returns a 404 error if the key does not exist.

Example:

curl http://127.0.0.1:6420/api/v2/data?type=txid&key=key1

Result:

Transaction APIs

Get unconfirmed transactions

API sets: READ

URI: /api/v1/pendingTxs
Method: GET
Args:
    verbose [bool] include verbose transaction input data

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours. The hours are the original hours the output was created with. The calculated hours are calculated based upon the current system time, and provide an approximate coin hour value of the output if it were to be confirmed at that instant.

Example:

curl http://127.0.0.1:6420/api/v1/pendingTxs

Create transaction from unspent outputs or addresses

API sets: TXN

URI: /api/v2/transaction
Method: POST
Args: JSON Body, see examples

Creates an unsigned transaction from a pool of unspent outputs or addresses. addresses and unspents cannot be combined, and at least one must have elements in their array.

The transaction will choose unspent outputs from the provided pool to construct a transaction that satisfies the requested outputs in the to field. Not all unspent outputs will necessarily be used in the transaction.

If ignore_unconfirmed is true, the transaction will not use any outputs which are being spent by an unconfirmed transaction. If ignore_unconfirmed is false, the endpoint returns an error if any unspent output is spent by an unconfirmed transaction.

change_address is optional. If not provided then the change address will default to an address from one of the unspent outputs being spent as a transaction input.

Refer to POST /api/v1/wallet/transaction for creating a transaction from a specific wallet.

POST /api/v2/wallet/transaction/sign can be used to sign the transaction with a wallet, but POST /api/v1/wallet/transaction can create and sign a transaction with a wallet in one operation instead. Otherwise, sign the transaction separately from the API.

The transaction must be fully valid and spendable (except for the lack of signatures) or else an error is returned.

    "hours_selection": {
        "type": "manual"

Get transaction info by id

API sets: READ

URI: /api/v1/transaction
Method: GET
Args:
    txid: transaction id
    verbose: [bool] include verbose transaction input data
    encoded: [bool] return the transaction as hex-encoded serialized bytes

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours. The hours are the original hours the output was created with. If the transaction is confirmed, the calculated hours are the hours the transaction had in the block in which it was executed.. If the transaction is unconfirmed, the calculated hours are based upon the current system time, and are approximately equal to the hours the output would have if it become confirmed immediately.

Inject raw transaction

API sets: TXN, WALLET

URI: /api/v1/injectTransaction
Method: POST
Content-Type: application/json
Body: {"rawtx": "hex-encoded serialized transaction string"}
Errors:
    400 - Bad input
    500 - Other
    503 - Network unavailable (transaction failed to broadcast)

Broadcasts a hex-encoded, serialized transaction to the network. Transactions are serialized with the encoder package. See coin.Transaction.Serialize.

If there are no available connections, the API responds with a 503 Service Unavailable error.

Note that in some circumstances the transaction can fail to broadcast but this endpoint will still return successfully. This can happen if the node's network has recently become unavailable but its connections have not timed out yet.

The recommended way to handle transaction injections from your system is to inject the transaction then wait for the transaction to be confirmed. Transactions typically confirm quickly, so if it is not confirmed after some timeout such as 1 minute, the application can continue to retry the broadcast with /api/v1/resendUnconfirmedTxns. Broadcast only fails without an error if the node's peers disconnect or timeout after the broadcast was initiated, which is a network problem that may recover, so rebroadcasting with /api/v1/resendUnconfirmedTxns will resolve it, or else the network is unavailable.

POST /api/v1/transaction accepts an ignore_unconfirmed option to allow transactions to be created without waiting for unconfirmed transactions to confirm.

Any unconfirmed transactions found in the database at startup are resent. So, if the network broadcast failed but the transaction was saved to the database, when you restart the client, it will resend.

It is safe to retry the injection after a 503 failure.

To disable the network broadcast, add "no_broadcast": true to the JSON request body. The transaction will be added to the local transaction pool but not be broadcast at the same time. Note that transactions from the pool are periodically announced, so this transaction will still be announced eventually if the daemon continues running with connectivity for enough time.

Example:

curl -X POST http://127.0.0.1:6420/api/v1/injectTransaction -H 'content-type: application/json' -d '{

Get transactions with pagination

URI: /api/v2/transactions
Method: GET
Args:
    addrs: Comma separated addresses [optional, returns all transactions if no address is provided]
    confirmed: Whether the transactions should be confirmed [optional, must be 0 or 1; if not provided, returns all]
    verbose: [bool] include verbose transaction input data
    page: Page number [optional, default to 1, must be greater than 0]
    limit: The transactions number per page [optional, default to 10, maximum to 100]
    sort: Sort the transactions by block seq [optional, default to asc, must be 'asc' or 'desc']

This API is almost the same as the v1 version, except that it would not return all transactions by default and has pagination supported. If there are unconfirmed transactions, they will be appended after the confirmed transactions.

If no argument is provided, the first 10 transactions will be returned. The response would have a page_info field which includes total pages, page size, and current page.

Example:

curl http://127.0.0.1:6420/api/v2/transaction?page=1024&limit=2

Resend unconfirmed transactions

Verify encoded transaction

API sets: READ

URI: /api/v2/transaction/verify
Method: POST
Content-Type: application/json
Args: {"unsigned": false, "encoded_transaction": "<hex encoded serialized transaction>"}

If the transaction can be parsed, passes validation and has not been spent, returns 200 OK with the decoded transaction data, and the "confirmed" field will be false.

If the transaction is structurally valid, passes validation but has been spent, returns 422 Unprocessable Entity with the decoded transaction data, and the "confirmed" field will be true. The "error" "message" will be "transaction has been spent".

"unsigned" may be specified in the request. If true, the transaction will report an error if it is fully signed. It will not report an error if the transaction is missing at least one signature, and the remainder of the transaction is valid. In the response, if the transaction has any unsigned inputs, the "unsigned" field will be true. If the request did not specify "unsigned" or specified it as false, the response will return an error for an unsigned transaction.

If the transaction can be parsed but does not pass validation, returns 422 Unprocessable Entity with the decoded transaction data. The "error" object will be included in the response with the reason why. If the transaction's inputs cannot be found in the unspent pool nor in the historical archive of unspents, the transaction "inputs" metadata will be absent and only "uxid" will be present.

If the transaction can not be parsed, returns 400 Bad Request and the "error" object will be included in the response with the reason why.

Example of valid transaction that has not been spent:

curl -X POST -H 'Content-Type: application/json' http://127.0.0.1:6420/api/v2/transaction/verify \

Get blocks in specific range

API sets: READ

URI: /api/v1/blocks
Method: GET, POST
Args:
    start: start seq
    end: end seq
    seqs: comma-separated list of block seqs
    verbose: [bool] return verbose transaction input data

This endpoint has two modes: range and seqs. The seqs parameter cannot be combined with start, end.

If start and/or end are provided, returns blocks in the range [start, end]. Both start and end sequences are included in the returned array of blocks.

If seqs is provided, returns blocks matching the specified sequences. seqs must not contain any duplicate values. If a block does not exist for any of the given sequence numbers, a 404 error is returned.

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours. The hours are the original hours the output was created with. The calculated hours are the hours the transaction had in the block in which it was executed.

curl http://127.0.0.1:6420/api/v1/blocks?start=101&end=102

Migrating from the unversioned API

The unversioned API are the API endpoints without an /api prefix. These endpoints are all prefixed with /api/v1 now.

-enable-unversioned-api was added as an option to assist migration to /api/v1 but this option was removed in v0.26.0.

To migrate from the unversioned API, add /api/v1 to all endpoints that you call that do not have an /api prefix already.

For example, /block would become /api/v1/block.

Migrating from the JSONRPC API

The JSONRPC-2.0 RPC API was deprecated in v0.25.0 and removed in v0.26.0.

Anyone still using this can follow this guide to migrate to the REST API:

• get_status is replaced by /api/v1/blockchain/metadata and /api/v1/health
• get_lastblocks is replaced by /api/v1/last_blocks
• get_blocks is replaced by /api/v1/blocks
• get_outputs is replaced by /api/v1/outputs
• inject_transaction is replaced by /api/v1/injectTransaction
• get_transaction is replaced by /api/v1/transaction

Migrating from /api/v1/spend

The POST /api/v1/spend endpoint is deprecated and will be removed in v0.26.0.

To migrate from it, use POST /api/v1/wallet/transaction followed by POST /api/v1/injectTransaction. Do not create another transaction before injecting the created transaction, otherwise you might create two conflicting transactions.

POST /api/v1/wallet/transaction has more options for creating the transaction than the /api/v1/spend endpoint. To replicate the same behavior as /api/v1/spend, use the following request body template:

{
    "hours_selection": {
        "type": "auto",
        "mode": "share",
        "share_factor": "0.5",
    },
    "wallet": {
        "id": "$wallet_id",
        "password": "$password"
    },
    "to": [{
        "address": "$dst",
        "coins": "$coins"
    }]
}

You must use a string for "coins" instead of an integer measured in "droplets" (the smallest unit of currency in Skycoin, 1/1000000 of a skycoin). For example, if you sent 1 Skycoin with /api/v1/spend you would have specified the coins field as 1000000. Now, you would specify it as "1".

Some examples:

• 123.456 coins: before 123456000, now "123.456"
• 0.1 coins: before 100000, now "0.1"
• 1 coin: before 1000000, now "1"

Extra zeros on the "coins" string are ok, for example "1" is the same as "1.0" or "1.000000".

Only provide "password" if the wallet is encrypted. Note that decryption can take a few seconds, and this can impact throughput.

The request header Content-Type must be application/json.

The response to POST /api/v1/wallet/transaction will include a verbose decoded transaction with details and the hex-encoded binary transaction in the "encoded_transaction" field. Use the value of "encoded_transaction" as the "rawtx" value in the request to /api/v1/injectTransaction.

Migration from /api/v1/explorer/address

The GET /api/v1/explorer/address was deprecated in v0.25.0 and removed in v0.26.0.

To migrate from it, use GET /api/v1/transactions?verbose=1.

/api/v1/explorer/address accepted a single address query parameter. /api/v1/transactions uses an addrs query parameter and accepts multiple addresses at once.

The response data is the same but the structure is slightly different. Compare the follow two example responses:

/api/v1/explorer/address?address=WzPDgdfL1NzSbX96tscUNXUqtCRLjaBugC:
