Rate Limits - Developer Portal - Nateq

Each API key is rate-limited per minute. Production keys have a higher ceiling than sandbox keys; an explicit per-key limit set in the dashboard overrides the default.

Environment	Default limit
Production (`tg_live_`)	1,000 requests / minute
Sandbox (`tg_test_`)	100 requests / minute

Response headers

Every response includes your current standing in the window:

Header	Meaning
`X-RateLimit-Limit`	Max requests allowed in the window
`X-RateLimit-Remaining`	Requests left in the current window
`Retry-After`	Seconds to wait (only on `429`)

When you exceed it

You’ll receive 429 Too Many Requests:

{
  "success": false,
  "error": {
    "code": "RATE_LIMIT_EXCEEDED",
    "message": "API key rate limit exceeded",
    "details": { "limit": 1000, "window": "1 minute", "retry_after_seconds": 60 }
  }
}

Back off and retry after Retry-After seconds, ideally with exponential backoff and jitter. Spread bulk work out rather than bursting.
