Endpoint
POSThttps://tts.forgemesh.io/v1/tts/baseWhen to prefer
Choose this endpoint when you need short-form TTS (1–500 characters) in one of 31 supported languages, want OpenAI-compatible behavior, and prefer pay-per-call micro-payments via x402 rather than managing API keys or subscriptions. Ideal for agents that need occasional TTS without long-term API key setup.
