# 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](https://github.com/tendermint/tendermint/tree/master/rpc/lib) which contains its own set of documentation and tests.
## Configuration
Set the `laddr` config parameter under `[rpc]` table in the `$TMHOME/config/config.toml` file or the `--rpc.laddr` command-line flag to the desired protocol://host:port setting. Default: `tcp://0.0.0.0:26657`.
## 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"
}
```
The first entry in the result-array (`96`) is the method this response correlates with. `96` refers to "ResultTypeBroadcastTx", see [responses.go](https://github.com/tendermint/tendermint/blob/master/rpc/core/types/responses.go) for a complete overview.
## 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
