BillyAPI Platform

Rate Limiting

Stay within the per-organization rate limit and back off correctly on 429.

To ensure service stability, the Billy API applies rate limits.

Current Limits

  • 600 requests per minute per organization

Handling Limits

When you exceed the limit, the API returns:

  • HTTP Code: 429 Too Many Requests
  • Header: Retry-After (number of seconds to wait before retrying)
  • Body:
{
  "detail": "Too Many Requests - backpressure applied (Header 'Retry-After' in seconds)"
}

Best Practices

  1. Use parallel requests moderately (max 5-10 simultaneous)
  2. Implement exponential backoff in case of 429 error
