Soundstat Rate Limits

SoundStat does not publish fixed numeric per-minute or per-second rate limits for its REST API. The terms of service state that SoundStat reserves the right to restrict access when usage limits are exceeded, but specific thresholds are not documented. In practice the primary governor on consumption is economic rather than a request-rate cap: unique track analysis is billed against a prepaid balance, so throughput is bounded by available funds and by the per-track volume bands. Repeated reads of already-analyzed tracks and the free recommendation endpoints are served without incurring analysis charges.

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

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

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Music, Audio Analysis, Audio Features, Rate Limiting, and Quotas.

Limits

REST API Requests account
requests
not published
No fixed numeric per-minute or per-second request-rate limit is documented.
Unique Track Analysis account
tracks
prepaid balance / volume bands
Analysis of a not-yet-seen track is billed per unique track; throughput is bounded by prepaid funds, not a request cap.
Free Recommendation Endpoints account
requests
subject to fair-use restriction
Similar, feature-target, and mixed recommendation endpoints are free; SoundStat may restrict access if usage limits are exceeded.

Policies

Usage-Based Restriction
SoundStat reserves the right to restrict access when usage limits are exceeded, per its terms of service.
Analysis Caching
Once a track is analyzed it is served from the corpus on subsequent requests without re-charging, reducing effective load and cost.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
