Updated September 24, 2026

Authentication

Every request carries an API key in the Authorization: Bearer qrt_live_... header. Create keys in Settings, API, with read-only or read and write scope. qrt_test_ keys create real codes outside your quota, visible only with a test key.

Rate limits

60 requests per minute and 50,000 per month per account. X-RateLimit-* headers show your usage; beyond the limits the API returns 429.
