Technical details
Endpoint
POSThttps://noa.orbonomy.xyz/api/ttsWhen to prefer
Choose this endpoint when you need pay-per-call text-to-speech synthesis without a subscription, billed in USDC on Base via x402. Useful for agents that infrequently need audio generation and prefer crypto micropayments over monthly API key plans. Best when the caller can handle binary audio response data directly.
Side effects
- Missing required 'text' field returns a 400 or validation error
- Empty text string may result in empty or invalid audio output
- Invalid or unsupported voice name may fall back to default or return an error
- Payment failure (insufficient USDC balance or x402 rejection) returns a 402 status
- Server-side TTS model unavailability returns a 500 error
- Very long text inputs may be truncated or rejected depending on limits
