Keybase

Keybase API

Keybase public HTTP JSON API (v1.0). Read-oriented endpoints for user lookup and discovery by social proof, PGP public-key fetch, Merkle-tree root and block retrieval for verification, and the salt/login/session and signature-posting flow. All responses use a status envelope of {code, name}; the API supports CORS.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate
    — a tool list derived from the published API contracts, not an existing server. The scorer already
    read the manifest and reported mcp_server correctly; the MCPServer type was crediting the artifact-type
    surfaces with a server that does not exist.'
