Default Limit: Maximum of 10 concurrent requests per API keyEnterprise: Higher limits available upon request - contact us
How Rate Limiting Works
Unlike traditional rate limits based on requests per minute, Pikzels uses a concurrent request model:- You can have up to 10 requests processing at the same time
- Once a request completes, that slot becomes available immediately
- There’s no time window - it’s purely based on active concurrent requests
Example Scenario
Handling Rate Limits
When you exceed the concurrent request limit, you’ll receive a429 error:
Best Practices
- Keep track of how many requests are currently running
- Before sending a new request, check if you’re at the 10-request limit
- If at limit, wait for existing requests to complete before sending new ones
- Implement exponential backoff for 429 errors (wait 1s, 2s, 4s, 8s, etc.)
