Sonix Rate Limits

Sonix does not publish fixed numeric request-rate limits for its REST API. Practical throughput is governed by two things: your plan's transcription / translation and AI-workspace hour allowances (per-hour on pay-as-you-go, or the bundled monthly hours on Core/Advanced/Pro), and per-request constraints such as the 100MB multipart upload size (larger files must be supplied via a file_url). Media listing is paginated at 100 items per page. Transcription is asynchronous, so clients should poll media/transcript status or use a completion webhook rather than issuing tight request loops.

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

It captures 6 rate-limit definitions, measuring requests, hours, bytes, and items.

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

Tagged areas include Audio Transcription, Transcription, Speech-to-Text, Rate Limiting, and Quotas.

Policies

Asynchronous Processing
Transcription, translation, exports, and AI analysis are asynchronous jobs; retrieve results by polling status or via a completion webhook (callback_url).
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses rather than polling aggressively.
