To ensure our platform remains stable and fair for everyone, the Aura API is rate-limited. We ask that developers use industry standard techniques for limiting calls, caching results, and retrying requests responsibly.

Sliding window algorithm

The Aura API uses a sliding window algorithm to track rate limits. The algorithm is based on a fixed window counter, which is a simple and accurate way to track rate limits. The counter is incremented for each request and decremented when the window slides. For more information, read this engineering post by Cloudflare describing the pattern in more detail. The default settings are as follows:
  • Requests per second: 5
