## What it is
The canonical specification of the Ethereum execution layer JSON-RPC API, written in OpenRPC and maintained by the Ethereum Foundation. It defines the standard methods all Ethereum execution clients implement, enabling interoperable tooling and swappable clients.

## Use cases
- implement an ethereum execution client with a conformant json-rpc api
- look up the exact parameters and return types of eth_* rpc methods
- build tooling that talks to any ethereum client interchangeably
- test client conformance against the standard rpc spec
- propose and standardize new ethereum rpc methods

## When to choose
- you are building or testing an ethereum execution client
- you need the authoritative reference for ethereum json-rpc methods
- you are developing wallets, indexers, or infrastructure that must support all clients

## When to avoid
- you want a client library or sdk to call ethereum from your app
- you need consensus layer (beacon) api specs
- you want a runnable ethereum node rather than a specification

## Facets
- artifact type: dataset
- maturity: active
- function: api-framework, documentation, developer-tools
- domain: blockchain, apis, documentation, developer-tools
- platform: cross-platform
- tags: ethereum, json-rpc, openrpc, specification, execution-layer, blockchain-api, web3
