Trustless Execution Layer REST API

Trustless Log Index is part of the Trustless Execution Layer API project, which defines endpoints for fully trustless chain access with Merkle proofs based on the assumed knowledge of a recent canonical block hash and number, which (if not available by other means) can be obtained by running a Beacon Light Client. The format of the new endpoints is similar to the Beacon REST API.
