Free limits
Numeric limits are not recorded in structured form for this provider.
In the provider's words
No rate limit published in the current V8 API docs (legacy v7 docs listed 2 requests/second on Free). Per-request size: /stream up to 1,000 characters, /speech up to 3,000, /synthesisTasks up to 500,000
The catch
Commercial use allowed, but free-plan users must attribute Unreal Speech with a link when publishing audio. First-party REST endpoints. No credit card required.
Free models: not listed yet.
Get started
This is a first-party API, not OpenAI-compatible, so there is no drop-in base URL. The endpoint, the key and a working example are in the official docs.
