How this service works
Paid AI API endpoints via x402 micropayments
Output
Returns a response object with a unique ID and a choices array containing the synthesized speech content. Each choice includes a message with role and content fields. When streaming is enabled, chunks are delivered progressively as the audio is generated.
Example use cases
Narrate a blog post aloud
“Take the intro paragraph of my blog post — 'Artificial intelligence is reshaping the world at an unprecedented pace.' — and generate spoken audio from it using Edge TTS so I can add it to my podcast.”
Streaming voice assistant reply
“I want to stream an Edge TTS audio response for this message: 'Your order has been confirmed and will arrive by Friday.' Enable streaming so playback starts immediately.”
Automated customer support voice
“Generate a spoken version of this support response for my IVR system: 'Thank you for calling. Our support hours are Monday through Friday, 9am to 5pm Eastern.' Use Edge TTS and keep it under 100 tokens.”

Choose this endpoint when you need pay-per-use text-to-speech without a subscription, especially when using Microsoft Edge TTS voices and you want to settle payments automatically via x402 USDC micropayments. Ideal for agents that need occasional TTS without committing to a monthly plan, or when building crypto-native workflows where on-chain payments are preferred.
