## OpenAPI

````yaml /cometbft/next/api-reference/rpc/openapi.yaml get /abci_query
openapi: 3.0.0
info:
  title: CometBFT RPC
  contact:
    name: CometBFT
    url: https://docs.cosmos.network/cometbft
  description: >
    CometBFT supports the following RPC protocols:


    * URI over HTTP

    * JSONRPC over HTTP

    * JSONRPC over websockets


    ## Configuration


    RPC can be configured by tuning parameters under `[rpc]` table in the

    `$CMTHOME/config/config.toml` file or by using the `--rpc.X` command-line

    flags.


    The default RPC listen address is `tcp://127.0.0.1:26657`.

    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.


    If testing using a local RPC node, under the `[rpc]`

    section change the `cors_allowed_origins` property, please add the URL of

    the site where this OpenAPI document is running, for example:

      `cors_allowed_origins = ["http://localhost:8088"]`

    or if testing from the official documentation site:

      `cors_allowed_origins = ["https://docs.cosmos.network"]`

    ## 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


    A REST like interface.

        curl localhost:26657/block?height=5

    ## JSONRPC/HTTP


    JSONRPC requests can be POST'd to the root RPC endpoint via HTTP.

        curl --header "Content-Type: application/json" --request POST --data '{"method": "block", "params": ["5"], "id": 1}' localhost:26657

    ## JSONRPC/websockets


    JSONRPC requests can be also 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.


    For example using the [websocat](https://github.com/vi/websocat) tool, you
    can subscribe for 'NewBlock` events

    with the following command:

        echo '{ "jsonrpc": "2.0","method": "subscribe","id": 0,"params": {"query": "tm.event='"'NewBlock'"'"} }' | websocat -n -t ws://127.0.0.1:26657/websocket
