Rate limit

A rate limit is a cap on how many API requests a client can make per unit of time. AI Detector API's free tier is rate-limited to keep abuse manageable; paid tiers have higher limits and predictable behavior.

When you exceed a rate limit, AI Detector API returns HTTP 429 (Too Many Requests) with a Retry-After header telling you how long to wait. SDKs handle this automatically with exponential backoff, but if you're hitting the REST endpoint directly, your code should respect the header.

See the API reference for current per-plan limits.
