  The ShapeShift Public API does not declare securitySchemes in its OpenAPI, but
  authentication is documented through its Auth operations: Sign-In With Ethereum
  (SIWE, EIP-4361). A client fetches a nonce (siweNonce), the wallet signs the
  SIWE message, and siweVerify returns a JWT bearer token used on authenticated
  endpoints (affiliate create/update). Read endpoints (assets, chains, swap
  quotes/rates/status) are public. Swap and affiliate endpoints also accept an
  X-Partner-Code header for partner/affiliate attribution (not authentication).
