Tendermint RPC

We are using Slate to power our RPC documentation. For generating markdown use:

go get github.com/davecheney/godoc2md

# from root of this repo
make rpc-docs

Pagination

Requests that return multiple items will be paginated to 30 items by default. You can specify further pages with the ?page parameter. You can also set a custom page size up to 10000 with the ?per_page parameter.

Documentation

Overview

## Protocols

The following RPC protocols are supported:

* URI over HTTP * JSONRPC over HTTP * JSONRPC over websockets

RPC is built using Tendermint's 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://0.0.0.0:27147`. 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:27147/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:27147/).

```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:27147/websocket`. Asynchronous RPC functions like event `subscribe` and `unsubscribe` are only available via websockets.

## Get the list

An HTTP Get request to the root RPC endpoint shows a list of available endpoints.

```bash curl 'localhost:27147' ```

> 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=_ ```

func BlockResults added in v0.15.0 

func BlockResults(heightPtr *int64) (*ctypes.ResultBlockResults, error)

BlockResults gets ABCIResults at a given height. If no height is provided, it will fetch results for the latest block.

Results are for the height of the block containing the txs. Thus response.results[5] is the results of executing getBlock(h).Txs[5]

```shell curl 'localhost:27147/block_results?height=10' ```

```go client := client.NewHTTP("tcp://0.0.0.0:27147", "/websocket") err := client.Start() 

if err != nil {
  // handle error
}

defer client.Stop() info, err := client.BlockResults(10) ```

> The above command returns JSON structured like this:

```json 

{
 "height": "10",
 "results": [
  {
   "code": "0",
   "data": "CAFE00F00D"
  },
  {
   "code": "102",
   "data": ""
  }
 ]
}

```

func BlockchainInfo 

func BlockchainInfo(minHeight, maxHeight int64) (*ctypes.ResultBlockchainInfo, error)

Get block headers for minHeight <= height <= maxHeight. Block headers are returned in descending order (highest first).

```shell curl 'localhost:27147/blockchain?minHeight=10&maxHeight=10' ```

```go client := client.NewHTTP("tcp://0.0.0.0:27147", "/websocket") err := client.Start() 

if err != nil {
  // handle error
}

defer client.Stop() info, err := client.BlockchainInfo(10, 10) ```

func BroadcastTxAsync 

func BroadcastTxAsync(tx types.Tx) (*ctypes.ResultBroadcastTx, error)

func BroadcastTxCommit(tx types.Tx) (*ctypes.ResultBroadcastTxCommit, error)

CONTRACT: only returns error if mempool.CheckTx() errs or if we timeout waiting for tx to commit.

If CheckTx or DeliverTx fail, no error will be returned, but the returned result will contain a non-OK ABCI code.

```shell curl 'localhost:27147/broadcast_tx_commit?tx="789"' ```

```go client := client.NewHTTP("tcp://0.0.0.0:27147", "/websocket") err := client.Start() 

if err != nil {
  // handle error
}

defer client.Stop() result, err := client.BroadcastTxCommit("789") ```

> The above command returns JSON structured like this:

```json 

{
	"error": "",
	"result": {
		"height": "26682",
		"hash": "75CA0F856A4DA078FC4911580360E70CEFB2EBEE",

func Subscribe 

func Subscribe(wsCtx rpctypes.WSRPCContext, query string) (*ctypes.ResultSubscribe, error)

Subscribe for events via WebSocket.

To tell which events you want, you need to provide a query. query is a string, which has a form: "condition AND condition ..." (no OR at the moment). condition has a form: "key operation operand". key is a string with a restricted set of possible symbols ( \t\n\r\\()"'=>< are not allowed). operation can be "=", "<", "<=", ">", ">=", "CONTAINS". operand can be a string (escaped with single quotes), number, date or time.

Examples: 

tm.event = 'NewBlock'								# new blocks
tm.event = 'CompleteProposal'				# node got a complete proposal
tm.event = 'Tx' AND tx.hash = 'XYZ' # single transaction
tm.event = 'Tx' AND tx.height = 5		# all txs of the fifth block
tx.height = 5												# all txs of the fifth block

Tendermint provides a few predefined keys: tm.event, tx.hash and tx.height. Note for transactions, you can define additional keys by providing tags with DeliverTx response. 

	DeliverTx{
		Tags: []*KVPair{
			"agent.name": "K",
		}
  }

	tm.event = 'Tx' AND agent.name = 'K'
	tm.event = 'Tx' AND account.created_at >= TIME 2013-05-03T14:45:00Z
	tm.event = 'Tx' AND contract.sign_date = DATE 2017-01-01
	tm.event = 'Tx' AND account.owner CONTAINS 'Igor'

See list of all possible events here https://godoc.org/github.com/tendermint/tendermint/types#pkg-constants

For complete query syntax, check out https://godoc.org/github.com/tendermint/tendermint/libs/pubsub/query.

```go import "github.com/tendermint/tendermint/libs/pubsub/query" import "github.com/tendermint/tendermint/types"

client := client.NewHTTP("tcp://0.0.0.0:27147", "/websocket") err := client.Start() 

if err != nil {
  // handle error
}

defer client.Stop() ctx, cancel := context.WithTimeout(context.Background(), timeout) defer cancel() query := query.MustParse("tm.event = 'Tx' AND tx.height = 3") txs := make(chan interface{}) err = client.Subscribe(ctx, "test-client", query, txs) 

go func() {
  for e := range txs {
    fmt.Println("got ", e.(types.EventDataTx))
	 }
}()

```
