This document contains the list of RPC services provided by the Tezos node. It is generated from the OCaml source code (master branch). Usage ***** In order to interact with a Tezos node, you may use RPC calls through the client using this command ``tezos-admin-client rpc post ``. For instance, if you wish to request the current balance of a given block and contract, you can call the associated RPC via the command : ``$ tezos-admin-client rpc post /blocks//proto/context/contracts//balance``. A RPC may takes an *input* and generates an *output* both in JSON format. For example, the previous RPC call, that does not require an input, would display on the standard output : ``{ "balance": "4000000000000" }``. When calling a RPC that requires an input through command-line, you will be prompted to provide the JSON input in your default configured text editor. Alternatively, you can provide the JSON input using command ``$ tezos-admin-client rpc post with ``. Don't forget to quote the JSON according to your shell rules. You can also obtain the list of RPCs on the command line with ``tezos-admin-client rpc list /``, and the description of each service using ``tezos-admin-client rpc format ``. Of course, you can use your standard HTTP tool or library as well to perform all these tasks.
