Hume AI · Rate Limits

Hume Ai Rate Limits

Hume rate-limits primarily through plan-based monthly TTS character allowances, EVI minutes, and concurrent connection caps. Specific HTTP RPS limits are not publicly documented; Expression Measurement is gated by job throughput.

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

It captures 5 rate-limit definitions, measuring characters, minutes, concurrent_connections, and requests.

An exhausted limit returns HTTP 429.

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.

Tagged areas include AI, Voice, Empathic, Emotion, and Multimodal.
