Sandbox applies rate limits to ensure stable and reliable API performance for all users. When you exceed the rate limit, subsequent requests return a 429 Too Many Requests status code.

Handling rate limits

When you receive a 429 response:
  1. Pause requests - Stop sending new requests temporarily
  2. Implement backoff - Wait before retrying (start with 1 second, then increase)
  3. Reduce frequency - Spread requests over time
async function makeRequestWithRetry(url, options, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    const response = await fetch(url, options);
    
    if (response.status === 429) {
      const waitTime = Math.pow(2, i) * 1000; // Exponential backoff
      await new Promise(resolve => setTimeout(resolve, waitTime));
      continue;
    }
    
    return response;
  }
  throw new Error('Max retries exceeded');
}
Once your request rate falls within the limits, API access automatically resumes.

​
Custom rate limits

If your app requires higher rate limits than the standard production limit of 100 requests per minute, you can request a custom rate limit increase.
Contact the support team with your use case, expected traffic, and business needs. The team reviews requests and configures suitable limits.
When requesting a rate limit increase, include:
  • Current rate limit you’re experiencing
  • Desired rate limit
  • Expected API usage patterns (burst vs sustained)
  • Business impact of current limits
