Technical details
Endpoint
POSThttps://api.hypercli.com/api/x402/flow/text-to-speechWhen to prefer
Choose this endpoint when you need a pay-per-call text-to-speech conversion at a flat $0.05 rate with no subscription, especially when voice cloning via reference audio, custom speaker selection, or style/language control is needed. Prefer over subscription-based TTS services when usage is sporadic or cost predictability per call matters.
Side effects
- Empty or missing text field returns validation error
- Unsupported language code causes generation failure
- Invalid reference audio URL causes voice cloning to fail
- Payment failure via x402 results in 402 response and no generation
- Job timeout if text is extremely long
- Invalid speaker ID returns error
