How this service works
OpenAI-compatible text to speech (MeloTTS): same request shape as OpenAI /v1/audio/speech (input, voice, model); returns a WAV file. Languages en, es, fr, zh, jp, kr via language. Up to 2000 characters, flat price, no API key. Also callable as GET with the same fields as query parameters.
Output
A WAV audio file containing the synthesized speech of the provided text in the requested language. The file is returned directly as binary audio data, ready for playback or downstream processing.
Example use cases
Multilingual podcast intro narration
“Turn this intro text into spoken audio in Spanish so I can use it as a podcast opening: 'Bienvenidos al episodio de hoy. Hoy hablaremos sobre inteligencia artificial y su impacto en la sociedad.'”
Accessibility audio for web content
“Generate a WAV audio file of this paragraph in English so I can add it as an audio alternative on our website: 'Our return policy allows you to send back any item within 30 days for a full refund.'”
Japanese customer greeting for app
“Convert this text to speech in Japanese and give me the WAV: '本日はご来店ありがとうございます。ご不明な点がございましたら、お気軽にお申し付けください。'”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/audio/speech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-API-key, flat-rate TTS solution with multilingual support (en/es/fr/zh/jp/kr) and OpenAI-compatible request format. Ideal for agent workflows that already use the OpenAI SDK shape but want a cost-predictable, keyless alternative. Best for short-to-medium texts under 2000 characters where WAV output is acceptable.
Side effects
- Input text exceeds 2000 characters — request may be rejected or truncated
- Unsupported language code — defaults to English or returns an error
- Empty input string — likely returns an error or silent audio
- Payment not processed (x402 protocol failure) — no audio returned
- Network timeout for longer text inputs
