Api Endpoint

voice.forgemesh.io

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.
