Checkiday Rate Limits

Machine-readable rate-limit definitions for the Checkiday Holiday and Event API routed through apilayer. Checkiday enforces per-API-key monthly request quotas and surfaces remaining quota on every response via the `x-ratelimit-limit-month` and `x-ratelimit-remaining-month` HTTP headers, which are also mirrored into the JSON response body as a `rateLimit` envelope.

Checkiday Rate Limits is the machine-readable rate-limit profile for Checkiday - National Holiday and Event API on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, across the free, basic, pro, enterprise, and custom tiers, measuring requests_per_month.

Limit state is signalled in the limitMonth, remainingMonth, and retryAfter response headers.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for quotaExceeded, unauthorized, and serviceUnavailable.

Tagged areas include Calendar, Holidays, Events, Rate Limiting, and Quotas.
