Limits & Rate Limiting

Rekognita API has restrictions on the number of requests and the volume of documents processed depending on your pricing plan.

Rate Limits

Plan	Requests/min	Documents/day	Max File Size
Free	10	50	10 MB
Pro	60	1,000	50 MB
Business	300	10,000	100 MB
Enterprise	Custom	Unlimited	500 MB

Rate Limit Headers

Every API response contains headers with limits information:

X-RateLimit-Limit: 60          # Max requests per window
X-RateLimit-Remaining: 45     # Remaining requests
X-RateLimit-Reset: 1705312800 # Reset Unix timestamp
Retry-After: 30               # Seconds until next request (on 429)

When the limit is exceeded

When the limit is exceeded, the API returns a 429 Too Many Requests status code:

{
  "error": {
    "code": "rate_limit_exceeded",
    "message": "You have exceeded the request limit. Try again in 30 seconds.",
    "retry_after": 30
  }
}

Recommendation: Implement exponential backoff using theRetry-After header. The Rekognita SDK does this automatically.
