⚠️ API Refactor Notice (July 2025)

The RISK API has been refactored to improve security, clarity, and functionality. Please review the new endpoints below. While the old endpoints are still available for backward compatibility, they are now considered deprecated and will be removed in a future version. Old APIs will continue to operate until end of August 2025. It is recommended to update your code now.

Key Changes:

• https://risk.markets/api/v0/has replaced https://risk.markets/api/
• New Endpoints: We have introduced new, more specific endpoints for fetching scores (/credit-score), calculating insurance quotes (/insurance/quote), and executing transactions (/insurance/execute).
• User Identification: New endpoints now support lookup by either username or userId for greater flexibility.
• Security: All transaction-related logic is now handled exclusively by secure, server-side endpoints.

General Info

Base URL

All API endpoints are accessed relative to the following base URL: https://risk.markets/api/v0

Authentication
