**APIs profiled:** 1

Merkle Manufactory Inc. is the company that builds Farcaster, a sufficiently decentralized social network, and Snapchain, the blockchain-like peer-to-peer network that stores and syncs Farcaster's social data. Its developer surface is open and protocol-based rather than a single hosted product API: Snapchain nodes serve an HTTP API (port 3381, /v1) and a gRPC API (port 3383) for reading casts, reactions, links, user data, verifications and on-chain events and for submitting signed messages; Mini Apps (formerly Frames v2) run inside the Farcaster feed; and Sign In with Farcaster (SIWF) plus AuthKit provide identity for third-party apps. The stack is fully open source under the farcasterxyz GitHub organization. Backed by a16z.
