The read/write REST interface a Snapchain node serves on port 3381 under the /v1 path. Read endpoints (casts, reactions, links, user data, verifications, fids, username proofs, storage limits, on-chain events, info, events) are unauthenticated; writes are performed by submitting protobuf-encoded, Ed25519-signed Farcaster messages to /v1/submitMessage. Snapchain is self-hosted node software (a drop-in replacement for Hubble); the default documented base address is a local node.
