How this service works
ElevenLabs text-to-speech: convert text to speech (MP3).
Output

Example use cases
Podcast intro narration
“Take this intro script — 'Today on the show, we explore the future of AI in healthcare' — and convert it to spoken audio using the Leo voice so I can use it as my podcast intro.”
Accessibility audio for article
“Convert this article summary to speech using the Ara voice: 'New research shows that daily exercise significantly reduces the risk of chronic illness, especially in adults over 40.' I need an MP3 to embed on the page.”
Voiceover for product demo
“Generate a voiceover using the Sal voice for this product demo script: 'Our app makes it effortless to track your goals, celebrate wins, and stay motivated every single day.' I need it as an MP3 for the video.”
Technical details
Endpoint
POSThttps://api.xona-agent.com/audio/x-text-to-speech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need high-quality neural text-to-speech synthesis via ElevenLabs voices and want to pay per-call with USDC via the x402 protocol. Prefer it over generic TTS APIs when voice variety (Eve, Ara, Leo, Rex, Sal) and ElevenLabs audio quality are specifically desired, and when you need MP3 output without managing your own ElevenLabs API key.
Side effects
- Text field missing or empty — endpoint requires non-empty text input
- Invalid voice_id value — must be one of Eve, Ara, Leo, Rex, or Sal
- Text too long — may exceed character limits supported by ElevenLabs
- Invalid output_format specification — unsupported codec or bitrate combination
- Payment failure — $0.01 USDC x402 payment not completed or insufficient funds
- Service unavailable — upstream ElevenLabs API unreachable
