Text to Speech API

br0ski777/text-to-speech-x402

Connects Claude to a text-to-speech API that generates MP3 audio files from text in over 50 languages. Uses the x402 micropayment system, so you'll need to handle payment integration to use the service. The server runs remotely at text-to-speech.api.klymax402.com via SSE transport, which means you don't need to host anything locally. Reach for this when you need to add voice output to workflows, generate audio content in multiple languages, or build accessibility features. The GitHub repo is pretty bare on documentation, so you'll likely need to experiment with the API directly to understand available voices, language codes, and pricing structure.
