Rate limiting - Upstack Data

The Upstack Data API rate limits requests per API key to protect the analytics backend. Limits are applied per key (and therefore per pixel), not per IP address.

Limits

Limits are modest and sized for dashboard and CLI traffic. If you’re building a high-volume integration — bulk exports, scheduled backfills — contact support and we can raise your limit.

Rate limit responses

When you exceed the limit, requests return 429 Too Many Requests:

{
  "message": "Too many requests. Retry later."
}

Retrying safely

Retry 429 responses with exponential backoff and jitter, respecting Retry-After when the response includes it.
Don’t retry 4xx responses other than 429 — fix the request instead.
Backfill and bulk-export jobs should serialize requests rather than fan out with unbounded concurrency; a small worker pool with backoff will finish faster than a burst that spends its time getting throttled.
