  description: "Tendermint supports the following RPC protocols:\n\n* URI over HTTP\n* JSONRPC over HTTP\n* JSONRPC over websockets\n\n## Configuration\n\nRPC can be configured by tuning parameters under `[rpc]` table in the\n`$TMHOME/config/config.toml` file or by using the `--rpc.X` command-line\nflags.\n\nDefault rpc listen address is `tcp://0.0.0.0:26657`.\nTo set another address, set the `laddr` config parameter to desired value.\nCORS (Cross-Origin Resource Sharing) can be enabled by setting\n`cors_allowed_origins`, `cors_allowed_methods`, `cors_allowed_headers`\nconfig parameters.\n\n## Arguments\n\nArguments which expect strings or byte arrays may be passed as quoted\nstrings, like `\"abc\"` or as `0x`-prefixed strings, like `0x616263`.\n\n## URI/HTTP\n\nA REST like interface.\n\n    curl localhost:26657/block?height=5\n\n## JSONRPC/HTTP\n\nJSONRPC requests can be POST'd to the root RPC endpoint via HTTP.\n\n    curl --header \"Content-Type: application/json\" --request POST --data '{\"method\": \"block\", \"params\": [\"5\"], \"id\": 1}' localhost:26657\n\n## JSONRPC/websockets\n\nJSONRPC requests can be also made via websocket.\nThe websocket endpoint is at `/websocket`, e.g. `localhost:26657/websocket`.\nAsynchronous RPC functions like event `subscribe` and `unsubscribe` are\nonly available via websockets.\n\nExample using https://github.com/hashrocket/ws:\n\n    ws ws://localhost:26657/websocket\n    > { \"jsonrpc\": \"2.0\", \"method\": \"subscribe\", \"params\": [\"tm.event='NewBlock'\"], \"id\": 1 }\n"
