note: >-
  Code exposes a gRPC/Protobuf API (code-protobuf-api), not a REST API, so there
  is no OpenAPI securityScheme to derive from. Authentication is self-custodial
  and protocol-level rather than API-key/OAuth based.

  - name: Ed25519 request signing
    type: self-custodial-keypair
    description: >-
      Clients sign gRPC requests (intents, swaps, messages) with an Ed25519
      keypair derived from the user's self-custodial wallet. No account
      registration, API key, or OAuth token is required ("no sign-up
      necessary"). Timelock accounts on Solana enforce ownership on-chain.

  - name: Webhook JWT verification
    type: jwt
    description: >-
      Server-side payment-event webhooks are delivered as JWT-signed
      notifications; the receiving server verifies the JWT signature to confirm
      the event originated from Code and was not tampered with.
