Authentication

Integrators can fetch quotes from Fabric without authentication, but such requests are subject to rate limits and dynamic fees.

For custom fee configuration, increased rate limits, observability, and better support, integrators can create an account to get an API key.

API Key Authentication

Authenticated requests must include the x-api-key header with the API key.

App Identification Header

Use the x-app-id header to identify the calling app or sub-account.

  • You choose your own app ID for basic identification
  • App IDs can be used to discriminate your traffic for analytics and debugging
