JSON-RPC Reference

This section is the authoritative reference for the JSON-RPC interface exposed by exfer node / exfer mine when started with --rpc-bind. The transport shape is JSON-RPC 2.0 over HTTP POST. The methods are not Bitcoin-compatible — Exfer is an extended-UTXO chain with its own protocol; see EXFER.md for the underlying spec.

What's here

• Transport — request/response envelope, HTTP semantics, how to enable the RPC server.
• Limits & back-pressure — body size caps, rate limits, HTTP 429 behavior.
• Error codes — the four JSON-RPC error codes Exfer uses.
• Protocol primitives — address / hash / amount / height / outpoint encoding, coinbase maturity, block cadence.
• Methods — one page per method:
  • get_block_height
  • get_block
  • get_transaction
  • get_balance
  • get_address_utxos
  • get_script_utxos
  • send_raw_transaction
• Confirmation depth & reorg semantics — how reorg resistance scales with depth.
• References — upstream sources and binaries.

Each method page has a "try it" widget that issues a real call against a community node so you can experiment without running a node locally.
