What is RPC in Tezos?

RPC is a client-server protocol where the requesting program is the client and the program providing the service is the server. Tezos nodes provide a JSON/RPC interface to interact with the Tezos network. Although it uses RPC and is JSON-based, it does not follow the JSON-RPC protocol. A complete list of calls is available here.

Tezos nodes act as servers and accept HTTP requests from clients and other nodes via this interface.

All the RPCs served by the Tezos node are described as an OpenAPI specification at Octez Node RPCs in the Octez documentation.
