Cyclecalcs Rate Limits

Per-caller rate limits on the CycleCalcs v2 API, enforced in three simultaneous windows; whichever window is closest to exhausted governs a given request. Only a request that reaches the origin function counts — a CDN cache hit costs no quota. The published limits are a floor, not a ceiling: tightening one is defined as a breaking change that cannot happen inside /v2.

Cyclecalcs Rate Limits is the machine-readable rate-limit profile for CycleCalcs on the APIs.io network, in the API Commons Rate Limits shape.

It captures 15 rate-limit definitions, across the Basic, Pro, Ultra, and Mega tiers, measuring requests_per_minute, requests_per_hour, requests_per_day, and requests_per_month.

Limit state is signalled in the rateLimit, rateLimitPolicy, legacyLimit, and legacyRemaining response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled, rangeTooLarge, responseTooLarge, and serviceUnavailable.

Tagged areas include Rate Limiting and Astronomy.
