How this service works
OpenAI-compatible text-to-speech endpoint (input, voice, response_format) for drop-in use with code already built against the OpenAI TTS API, 1 of 10 standard voices, up to 500 characters, WAV/FLAC/OGG output. Use it to: swap OpenAI TTS calls for a pay-per-call x402 alternative, generate speech from an existing OpenAI-style client, avoid API-key management for short text-to-audio requests. USDC on Base.
Output
An audio file (WAV, FLAC, or OGG) containing the synthesized speech of the input text, returned as a binary audio response with the appropriate content-type header (e.g. audio/wav). The response is OpenAI-compatible.
Example use cases
Example prompt
“Read this paragraph aloud using a calm female persona voice and give me the audio as a WAV file: 'Welcome to ForgeMesh, where your AI agent finally has a voice worth hearing.'”
