Audd Rate Limits

AudD gates access primarily through request quotas rather than fine-grained per-second rate limits. Without an api_token, usage is capped at 10 requests per method per day. With a token, the 300-request free allotment and any monthly plan limits apply; additional usage is billed per 1,000 requests. The enterprise endpoint counts one request per 12 seconds of audio scanned. Specific per-second throttling values are not documented publicly.

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

It captures 4 rate-limit definitions, measuring requests.

An exhausted limit returns HTTP 200.

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 2 backoff/retry policies defined and response codes documented for throttled and throttledBody.

Tagged areas include Music, Music Recognition, Audio, Fingerprinting, and Rate Limiting.

Policies

Quota-Based Access
Access is controlled by free allotment and purchased monthly request quotas rather than per-second throttling.
Backoff Strategy
Errors, including rate-limit and quota errors, arrive as HTTP 200 with "status": "error" and a numeric error_code (AudD, 2026-10-07; ErrorResponse in https://audd.io/openapi.json). Check status on every response; back off on a limit error code rather than waiting for a 429, which AudD does not send.
