Acast Rate Limits

The Acast Publishing API documents a single published rate limit of 60 requests per minute. Beyond the request-rate cap, episode creation is bounded by a maximum audio file size of 150 MB (MP3 recommended at 128 kbps). API keys are scoped to a user and only reach the shows assigned to that user, which further bounds the data any single key can act on.

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

It captures 3 rate-limit definitions, measuring requests, bytes, and shows.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Podcasting, Publishing, Rate Limiting, and Quotas.
