 RPC
 ===
 
-Coming soon: RPC docs powered by `slate <https://github.com/lord/slate>`__. Until then, read on.
-
-Tendermint supports the following RPC protocols:
-
--  URI over HTTP
--  JSONRPC over HTTP
--  JSONRPC over websockets
-
-Tendermint RPC is build using `our own RPC
-library <https://github.com/tendermint/tendermint/tree/master/rpc/lib>`__.
-Documentation and tests for that library could be found at
-``tendermint/rpc/lib`` directory.
-
-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://0.0.0.0:46657``.
-
-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
-~~~~~~~~
-
-Example request:
-
-.. code:: bash
-
-    curl -s 'http://localhost:46657/broadcast_tx_sync?tx="abc"' | jq .
-
-Response:
-
-.. code:: 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:46657/``).
-
-Example request:
-
-.. code:: 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. ``http://localhost:46657/websocket``. Asynchronous
-RPC functions like event ``subscribe`` and ``unsubscribe`` are only
-available via websockets.
-
-Endpoints
-~~~~~~~~~
-
-An HTTP Get request to the root RPC endpoint (e.g.
-``http://localhost:46657``) shows a list of available endpoints.
-
-::
-
-    Available endpoints:
-    http://localhost:46657/abci_info
-    http://localhost:46657/dump_consensus_state
-    http://localhost:46657/genesis
-    http://localhost:46657/net_info
-    http://localhost:46657/num_unconfirmed_txs
-    http://localhost:46657/health
-    http://localhost:46657/status
-    http://localhost:46657/unconfirmed_txs
-    http://localhost:46657/unsafe_flush_mempool
-    http://localhost:46657/unsafe_stop_cpu_profiler
-    http://localhost:46657/validators

-tx
-~~
-
-Returns a transaction matching the given transaction hash.
-
-**Parameters**
-
-1. hash - the transaction hash
-2. prove - include a proof of the transaction inclusion in the block in
-   the result (optional, default: false)
-
-**Returns**
-
--  ``proof``: the ``types.TxProof`` object
--  ``tx``: ``[]byte`` - the transaction
--  ``tx_result``: the ``abci.Result`` object
--  ``index``: ``int`` - index of the transaction
--  ``height``: ``int`` - height of the block where this transaction was
