  title: Turnkey 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.
