How this service works
Paid text-to-speech via x402. WAV audio in 31 languages, OpenAI-compatible, no API keys.
Output
Returns a binary audio file (WAV, FLAC, or OGG) containing the synthesized speech rendered by ForgeMesh Voice. The response content type is audio/wav (or the requested format), and the audio can be played back directly or saved to disk. No JSON wrapper — it is a raw audio stream.
Example use cases
Podcast intro narration
“Generate a spoken audio clip using a deep male voice — use M3 — and save it as a WAV file. The text is: 'Welcome to TechTalks Weekly, your source for the latest in software and innovation.'”
Multilingual customer greeting
“Convert this French greeting to speech using a female voice F1 and give me an OGG file: 'Bonjour et bienvenue chez NovaBoutique. Comment pouvons-nous vous aider aujourd'hui?'”
Accessibility audio for article
“I need a WAV audio version of this paragraph for visually impaired readers using voice M4: 'Our quarterly earnings exceeded expectations, with a 12% growth in net revenue compared to last year.'”

POSThttps://tts.forgemesh.io/v1/audio/speechWhen to prefer
Choose ForgeMesh TTS when you need pay-per-call speech synthesis with no API key registration, no subscription, and no monthly commitment — ideal for agents that call TTS infrequently or need to spin up quickly. It is OpenAI-compatible, so switching cost is low. Prefer this over OpenAI TTS or ElevenLabs when you want x402 micropayment billing and broad language coverage (31 languages) with a simple 10-voice palette.
Side effects
- Text input exceeds 2000 characters — request rejected with error
- Invalid voice identifier (not in M1-M5 or F1-F5) — bad request error
- Payment via x402 fails or insufficient USDC balance — 402 Payment Required response
- Unsupported language or character set in input — may produce degraded or silent output
- Invalid response_format value — falls back to WAV or returns error
