Unauthenticated REST Interface
The REST API can be enabled with the -rest
option.
Supported API
GET /rest/tx/TX-HASH.{bin|hex|json}
Given a transaction hash, Returns a transaction, in binary, hex-encoded binary or JSON formats.
For full TX query capability, one must enable the transaction index via "txindex=1" command line / configuration option.
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.
The HTTP request and response are both handled entirely in-memory, thus making maximum memory usage at least 2.66MB (1 MB max block, plus hex encoding) per request.
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.
GET /rest/chaininfo.json
Returns various state info regarding block chain processing. Only supports JSON as output format.
- chain : (string) current network name as defined in BIP70 (main, test, regtest)
- blocks : (numeric) the current number of blocks processed in the server
- headers : (numeric) the current number of headers we have validated
- bestblockhash : (string) the hash of the currently best block
- difficulty : (numeric) the current difficulty
- verificationprogress : (numeric) estimate of verification progress [0..1]
- chainwork : (string) total amount of work in active chain, in hexadecimal
GET /rest/getutxos
The getutxo command allows querying of the UTXO set given a set of of outpoints. See BIP64 for input and output serialisation: https://github.com/bitcoin/bips/blob/master/bip-0064.mediawiki
Risks
Running a webbrowser on the same node with a REST enabled bitcoind 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.
