Unauthenticated REST Interface

The REST API can be enabled with the -rest option.

The interface runs on the same port as the JSON-RPC interface, by default port 8332 for mainnet, port 18332 for testnet, port 38332 for signet, and port 18443 for regtest.

REST Interface consistency guarantees

The same guarantees as for the RPC Interface apply.

Supported API

Transactions

GET /rest/tx/<TX-HASH>.<bin|hex|json>

Given a transaction hash: returns a transaction in binary, hex-encoded binary, or JSON formats.

By default, this endpoint will only search the mempool. To query for a confirmed transaction, enable the transaction index via "txindex=1" command line / configuration option.

Blocks

GET /rest/block/<BLOCK-HASH>.<bin|hex|json> GET /rest/block/notxdetails/<BLOCK-HASH>.<bin|hex|json>

Given a block hash: returns a block, in binary, hex-encoded binary or JSON formats. Responds with 404 if the block doesn't exist.

The HTTP request and response are both handled entirely in-memory.

With the /notxdetails/ option JSON response will only contain the transaction hash instead of the complete transaction details. The option only affects the JSON response.

Blockheaders

GET /rest/headers/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>

Given a block hash: returns amount of blockheaders in upward direction. Returns empty if the block doesn't exist or it isn't in the active chain.

Deprecated (but not removed) since 24.0: GET /rest/headers/<COUNT>/<BLOCK-HASH>.<bin|hex|json>

Blockfilter Headers

GET /rest/blockfilterheaders/<FILTERTYPE>/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>

Given a block hash: returns amount of blockfilter headers in upward direction for the filter type . Returns empty if the block doesn't exist or it isn't in the active chain.

Deprecated (but not removed) since 24.0: GET /rest/blockfilterheaders/<FILTERTYPE>/<COUNT>/<BLOCK-HASH>.<bin|hex|json>

Blockfilters

GET /rest/blockfilter/<FILTERTYPE>/<BLOCK-HASH>.<bin|hex|json>

Given a block hash: returns the block filter of the given block of type . Responds with 404 if the block doesn't exist.

Blockhash by height

GET /rest/blockhashbyheight/<HEIGHT>.<bin|hex|json>

Given a height: returns hash of block in best-block-chain at height provided.

Chaininfos

GET /rest/chaininfo.json

Returns various state info regarding block chain processing. Only supports JSON as output format. Refer to the getblockchaininfo RPC help for details.

Deployment info

GET /rest/deploymentinfo.json GET /rest/deploymentinfo/<BLOCKHASH>.json

Returns an object containing various state info regarding deployments of consensus changes at the current chain tip, or at if provided. Only supports JSON as output format. Refer to the getdeploymentinfo RPC help for details.

Query UTXO set

GET /rest/getutxos/<checkmempool>/<txid>-<n>/<txid>-<n>/.../<txid>-<n>.<bin|hex|json>

The getutxo command allows querying of the UTXO set given a set of outpoints. See BIP64 for input and output serialisation: https://github.com/BGL/bips/blob/master/bip-0064.mediawiki

Example:

$ curl localhost:18332/rest/getutxos/checkmempool/b2cdfd7b89def827ff8af7cd9bff7627ff72e5e8b0f71210f92ea7a4000c5d75-0.json 2>/dev/null | json_pp

   "bitmap": "1",
   "utxos" : [

         "height" : 2147483647,
         "value" : 8.8687,

            "desc" : "addr(mi7as51dvLJsizWnTMurtRmrP8hG2m1XvD)#gj9tznmy"
            "hex" : "76a9141c7cebb529b86a04c683dfa87be49de35bcf589e88ac",
            "type" : "pubkeyhash",
            "address" : "mi7as51dvLJsizWnTMurtRmrP8hG2m1XvD"
         }
      }
   ]
}

Memory pool

GET /rest/mempool/info.json

Returns various information about the transaction mempool. Only supports JSON as output format. Refer to the getmempoolinfo RPC help for details.

GET /rest/mempool/contents.json

Returns the transactions in the mempool. Only supports JSON as output format. Refer to the getrawmempool RPC help for details.

Risks

Running a web browser on the same node with a REST enabled BGLd can be a risk. Accessing prepared XSS websites could read out tx/block data of your node by placing links like <script src="http://127.0.0.1:8332/rest/tx/1234567890.json"> which might break the nodes privacy.
