Rate Limits

Although the API is free, there are very lenient rate limits posed to prevent API abuse.

The current rate limit is 100 requests per second for uncached requests. Cached requests are not subject to rate limits.

The cached status of requests are identified in the headers as cf-cache-status.

  • HIT: cache hit (no rate limit)
  • MISS: cache miss

Note that rate limit header values (x-ratelimit-limit 100, x-ratelimit-remaining and x-ratelimit-reset) are not valid on cached requests.
