Frequently Asked Questions

How does API authentication work?

HMAC signature authentication (mandatory on fund-related endpoints), with per-language signing samples and an error-code reference; the sandbox gets your first integration done in about ten minutes.

Are there SDKs?

The AI gateway is fully compatible with the official OpenAI / Anthropic SDKs; other business lines expose REST APIs with request samples, and all webhook events share one signature scheme.
