How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns a JSON object containing the audio file URL (audio_url), the audio format (e.g. mp3), and the duration of the generated speech in seconds. The agent can use the audio_url to stream or download the synthesized speech.
Example use cases
Podcast intro voiceover generation
“Turn this script into spoken audio with a warm, professional voice: 'Today on the show, we're diving deep into the future of AI agents and what it means for everyday people.' I need the audio URL so I can drop it into my podcast editor.”
Accessibility audio version of article
“I have this article text and I want to create an audio version for visually impaired readers — can you synthesize speech from it using a clear, neutral voice? Here's the text: 'Artificial intelligence is transforming industries at an unprecedented pace...'”
AI agent spoken response output
“My assistant needs to speak its response out loud — take this message and generate a speech audio file from it: 'Your meeting is scheduled for 3pm tomorrow with the engineering team.' Use a natural-sounding voice.”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/llm/ttsWhen to prefer
Choose this endpoint when you need a simple pay-per-call text-to-speech conversion without a subscription, especially in an agentic workflow using the x402 payment protocol. Suitable for one-off narration, accessibility audio, or dynamic voice output where you don't want to maintain a TTS provider account. Best when cost per call ($0.10 USDC) is acceptable and you need a URL-based audio output.
Side effects
- Empty or missing text field returns a validation error
- Text too long may exceed model limits and return an error or truncated audio
- Invalid voice name may fall back to default or return an error
- Service unavailable returns a non-200 response with no audio URL
- Payment failure via x402 protocol prevents the call from completing
