Astronomy Api Rate Limits

Astronomy API ENFORCES rate limiting but PUBLISHES NO NUMBERS. The docs confirm the mechanism, the scope and the status code, and state nothing about the threshold, the window, the burst allowance or any response header.

Astronomy Api Rate Limits is the machine-readable rate-limit profile for Astronomy API on the APIs.io network, conforming to the API Commons Rate Limits specification.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled, throttled_documented, timeout, timeout_note, quotaExceeded, and serviceUnavailable.

Tagged areas include Astronomy, Celestial Data, Space, Moon Phases, and Star Charts.

Policies

Backoff
The docs say only "Retrying after some time will resolve this error". No Retry-After header, no interval, no backoff algorithm is specified.
Escalation
Higher throughput is obtained by emailing contact@astronomyapi.com; there is no self-serve upgrade path and no published tier ceiling.
