How this service works
AI-made art, prompts, stories and guides — fresh every day.
Output
Returns a JSON object containing the language code used, a base64-encoded WAV audio file (16-bit PCM at 44.1 kHz), the number of characters processed, the model name ('melotts'), and the MIME type ('audio/wav'). The agent must decode the base64 string to obtain a playable WAV file.
Example use cases
Multilingual podcast intro narration
“Convert this French intro text into spoken audio: 'Bienvenue dans notre émission quotidienne sur l'intelligence artificielle.' I need it as a WAV file.”
Accessibility audio for written content
“Read aloud this short English paragraph as audio so I can add it to my article: 'AI is transforming creativity in ways we never imagined possible.'”
Spanish voiceover for a guide
“Generate a Spanish voice recording of this sentence for my tutorial: 'Este es tu guía diario de arte e historias creadas por inteligencia artificial.'”
Technical details
Endpoint
POSThttps://autopilot-studio.kariguetoazul.workers.dev/v1/tts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, multilingual text-to-speech synthesis returning a base64 WAV file, especially for short texts (under 600 chars) in English, Spanish, French, Chinese, Japanese, or Korean. It is cost-effective at $0.01 per call via x402 and runs on Cloudflare Workers for low-latency global access. Prefer it for quick narration, accessibility overlays, or voice snippets rather than long-form audiobook generation.
Side effects
- Text exceeds 600 characters — likely returns an error or truncation
- Unsupported language code passed outside of [en, es, fr, zh, jp, kr] — validation error
- Empty text input — may return an error or silent audio
- Network timeout on Cloudflare Worker — transient 502/503 error
- Payment failure via x402 protocol — 402 response, audio not returned
