To maintain platform stability and ensure fair usage across all clients, PCE APIs enforce a rate limiting mechanism. This helps protect the system from excessive traffic while ensuring consistent performance for all integrations.

Rate Limit Policy

Our APIs currently support the following rate limit:

What Happens When You Exceed the Limit?

If your application exceeds the defined rate limit:

• The API will return 429: Too Many Requests response
• Additional requests within the time window will be rejected (dropped)
• Normal processing resumes automatically once the rate window resets

Best Practices

To ensure a smooth integration experience and avoid throttling:

• Implement retry logic with exponential backoff
• Avoid burst traffic by distributing requests evenly
• Cache responses where applicable to reduce redundant API calls
• Monitor API usage to stay within thresholds

Recommended Handling Strategy

When receiving 429 response:

• Pause further requests temporarily
• Retry the request after a short delay
• Gradually increase retry intervals if limits continue to be hit
