Rate limiting

All endpoints share a per-client rate limit.

Setting	Value
Limit	100 requests per minute
Window	Fixed 60-second window
Tracking	Per client (all API keys for a client share one quota)

Response headers

Every response includes:

Header	Description
`X-Rate-Limit-Limit`	Maximum requests allowed (currently `100`).
`X-Rate-Limit-Window`	Window length in milliseconds (`60000`).

When you exceed the limit, the response also includes:

Header	Description
`Retry-After`	Seconds to wait before the next request will be accepted.

{
  "statusCode": 429,
  "message": "Rate limit exceeded for this client. Please wait before making more requests.",
  "error": "Too Many Requests"
}

Back off on 429 for at least the number of seconds in Retry-After.
If you control multiple integrations against the same client, coordinate their schedules — they share a single quota.
For backfills, prefer limit=1000 and serial paging over many parallel small requests.
