API Keys

Get current API key quota

Returns the daily and monthly quotas for the authenticated API key. Another key cannot be selected. Both limits can apply at once. Quota reflects settled, aggregated consumption and is not a real-time admission decision or settlement record.

The response is an approximate snapshot, not a guarantee of request admission. The service may reuse a snapshot for about two seconds. as_of is the UTC time the snapshot was generated. Responses include Cache-Control: no-store; clients and intermediaries should not cache them. Monetary values are decimal strings; use a decimal or fixed-point type for calculations.
