Merkle Manufactory Inc.
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.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Merkle Manufactory Inc. the way a machine reads it — 3 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Merkle Manufactory Inc. scores 22.6/100 (emerging), with a separate agent-readiness read of 18/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Merkle Manufactory Inc.
Each block below is one kind of artifact we hold for Merkle Manufactory Inc.. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Snapchain HTTP API
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, ...
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
