LMNT · Rate Limits

Lmnt Rate Limits

LMNT does not impose concurrency or rate limits on paid plans (Indie, Pro, Premium, and Enterprise). The free tier is subject to usage limits enforced via monthly character quotas. API version 1.1+ adds a request-id header on every response to facilitate debugging and support. Errors use a structured error envelope.

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

It captures 2 rate-limit definitions.

Limit state is signalled in the request-id and X-API-Key response headers.

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.

Tagged areas include Text-to-Speech, Voice Synthesis, Voice Cloning, Audio Streaming, and Conversational AI.
