Rate limits

Per-key rate limit

All endpoints are rate-limited at 5 requests per second per API key, using a sliding window. Exceeding the limit returns a 429 response:

{
  "detail": "Rate limit exceeded"
}

Back off and retry after a short delay. The window resets within one second.

Monthly quotas

/ip, /email, and /phone are metered. Each plan includes a monthly call allowance. When you exhaust it, those endpoints return 403:

{
  "detail": {
    "error": "quota_exceeded",
    "reason": "plan_quota_exhausted",
    "api": "ip",
    "subscribe_url": "https://tracenow.io/app/subscribe"
  }
}

/trace, /identify, and /validate are not metered and are not subject to monthly quotas.
