Rate limits

Per-key request budgets and response headers.

Default budget: 60 requests per rolling minute per key. Up to 5 active keys per account.

Response headers

  • X-RateLimit-Limit: Requests allowed per rolling minute.
  • X-RateLimit-Remaining: Requests left in the current window.
  • X-Kvantrank-Date-UTC: UTC date of the pipeline snapshot in the payload.

Errors

  • 401: Missing or invalid API key.
  • 429: Rate limit exceeded. Retry after 60 seconds.
  • 503: API not configured on this deployment.

Snapshot fields (price, cap, volume) align to the same UTC pipeline run as Kvantrank scores. Intraday charting may need a separate live feed.
