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. `GET /rest/block/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. For full TX query capability, one must enable the transaction index via "txindex=1" command line / configuration option. 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 `
