Endpoint
POSThttps://x402-hub.vercel.app/api/edge-tts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need high-quality, Microsoft Edge TTS-powered speech synthesis accessible via a micropayment (x402/USDC on Base) without managing your own TTS API keys. Prefer it for per-call, pay-as-you-go voice generation in agent workflows where Azure or Google TTS subscriptions are overkill.
Side effects
