1. What Are Rate Limits
Rate limits control how frequently you can make API requests to SMM.BZ in a given time window. They protect platform stability and ensure fair access for all users.
2. Default Limits
- Order placement — 60 requests per minute per API key.
- Order status checks — 120 requests per minute per API key.
- Balance checks — 30 requests per minute per API key.
- Service list — 10 requests per hour (response is cached; use it once on startup).
3. Rate Limit Headers
Every API response includes headers so you can track your remaining quota:
X-RateLimit-Limit— your limit per windowX-RateLimit-Remaining— requests remainingX-RateLimit-Reset— Unix timestamp when the window resets
4. Handling 429 Errors
If you exceed your limit, you'll receive a 429 Too Many Requests response. Implement exponential backoff: wait 1s, then 2s, then 4s before retrying.
5. Higher Limits
Enterprise and Growth plan users can request higher rate limits. Contact support with your use case.
