API Playground: https://metamask.github.io/api-playground/api-documentation

JSON-RPC API provided by MetaMask.

MetaMask dapp developers lack a formal RPC specification. This attempts to document which methods MetaMask supports in a way that's versionable, human-readable and machine-readable. It will improve the accuracy of documentation, API, and clients.

MetaMasks effectiveness as an enterprise-grade application platform depends on its ability to provide a reliable and predictable developer experience.

Edit the openrpc.json file.

You can then run yarn run build to generate the output file again.

To test the result, you can paste the resulting file from dist/build/openrpc.json into the OpenRPC playground and view the result.
