Authentication & Security 5

Euler Finance Prices API declares 5 security schemes for authenticating requests. An API key is passed in the header as X-API-Key (ApiKeyAuth). It accepts HTTP bearer tokens (API key) (BearerAuth). An API key is passed in the header as X-Admin-Secret (AdminSecret). An API key is passed in the cookie as euler_platform_session (PlatformSession). An API key is passed in the header as X-CSRF-Token (PlatformCsrf).

  • ApiKeyAuth — API key authentication (optional; higher rate limits).
