## Authentication and requests

Send API keys in `X-API-Key`; use `Authorization: Bearer ...` for OAuth. Keep credentials server-side. [Authentication](/guides/authentication) covers setup and payment protocols.

The interactive playground sends real API requests. Requests follow [endpoint pricing](/concepts/pricing) and [rate limits](/concepts/quotas-and-limits). Errors use the envelope documented in [Error Handling](/guides/error-handling).

Use [Client setup](/sdks) for SDK configuration and [Pagination](/guides/pagination) for cursor handling.
