This API reference is intentionally curated. Internal, admin, and wallet-resolution endpoints are excluded from public docs.

​
API coverage

Krypton publishes a focused subset of endpoints across four services:
  • Backend API: account creation/sign-in, username setup, KYC, and payments.
  • Web3 API: transaction state plus read-only pricing and quote endpoints.
  • Hedge Fund API: strategy discovery and read-only strategy data.
  • Clark API: query, conversation, and memory endpoints for the Clark assistant. For a user-journey overview (not implementation detail), see Clark → Introduction.

​
Authentication

Use your auth token in the Authorization header:
Some endpoints have service-specific auth behavior defined directly in the OpenAPI spec.
