/* # Introduction Tendermint supports the following RPC protocols: * URI over HTTP * JSONRPC over HTTP * JSONRPC over websockets Tendermint RPC is built using our own RPC library which contains its own set of documentation and tests. See it here: https://github.com/tendermint/tendermint/tree/master/rpc/lib ## Configuration RPC can be configured by tuning parameters under `[rpc]` table in the `$TMHOME/config/config.toml` file or by using the `--rpc.X` command-line flags. Default rpc listen address is `tcp://0.0.0.0:26657`. To set another address, set the `laddr` config parameter to desired value. CORS (Cross-Origin Resource Sharing) can be enabled by setting `cors_allowed_origins`, `cors_allowed_methods`, `cors_allowed_headers` config parameters. ## Arguments Arguments which expect strings or byte arrays may be passed as quoted strings, like `"abc"` or as `0x`-prefixed strings, like `0x616263`. ## URI/HTTP ```bash curl 'localhost:26657/broadcast_tx_sync?tx="abc"' ``` > Response: ```json { "error": "", "result": { "hash": "2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF", "log": "", "data": "", "code": "0" }, "id": "", "jsonrpc": "2.0" } ``` ## JSONRPC/HTTP JSONRPC requests can be POST'd to the root RPC endpoint via HTTP (e.g. `http://localhost:26657/`). ```json { "method": "broadcast_tx_sync", "jsonrpc": "2.0", "params": [ "abc" ], "id": "dontcare" } ``` ## JSONRPC/websockets JSONRPC requests can be made via websocket. The websocket endpoint is at `/websocket`, e.g. `localhost:26657/websocket`. Asynchronous RPC functions like event `subscribe` and `unsubscribe` are only available via websockets. ## More Examples See the various bash tests using curl in `test/`, and examples using the `Go` API in `rpc/client/`. ## Get the list An HTTP Get request to the root RPC endpoint shows a list of available endpoints. ```bash curl 'localhost:26657' ``` > Response: ```plain Available endpoints: /abci_info /dump_consensus_state /genesis /net_info /num_unconfirmed_txs /status /health /unconfirmed_txs /unsafe_flush_mempool /unsafe_stop_cpu_profiler /validators Endpoints that require arguments: /abci_query?path=_&data=_&prove=_ /block?height=_ /blockchain?minHeight=_&maxHeight=_ /broadcast_tx_async?tx=_ /broadcast_tx_commit?tx=_ /broadcast_tx_sync?tx=_ /commit?height=_ /dial_seeds?seeds=_ /dial_persistent_peers?persistent_peers=_ /subscribe?event=_ /tx?hash=_&prove=_ /unsafe_start_cpu_profiler?filename=_ /unsafe_write_heap_profile?filename=_ /unsubscribe?event=_ ``` # Endpoints */ package core
