  title: Turnkey Organizations API
  description: 'Turnkey is secure wallet infrastructure: an API-first key-management and signing platform that generates private keys and signs payloads inside verifiable secure enclaves (TEEs). The public API is an RPC-style REST API under https://api.turnkey.com/public/v1 split into two families - read-only `query` endpoints and state-changing `submit` activity endpoints. Every request is an HTTP POST carrying an `X-Stamp` (or `X-Stamp-Webauthn`) header containing a digital signature over the exact JSON POST body. The stamp is verified by Turnkey''s secure enclaves before the request is processed and checked against the organization''s policy engine.'
