Self hostable voice AI API for building production voice agents with a typed REST API, webhooks, and a developer dashboard.

Users connect, set a spending cap, and you call any model through one SDK, charged to them, not you.

About Voice API

Self hostable voice AI API for building production voice agents with a typed REST API, webhooks, and a developer dashboard. Voice API gives you a typed product surface for agents, calls, and phone numbers so you can ship without rebuilding telephony plumbing. Clone the repo, install dependencies, and run the app locally. Create an outbound call with POST /api/v1/calls, then open transcripts, summaries, and outcomes when it finishes. Connect Twilio with your own keys, choose models on the platform, and hook finished calls into n8n or your own webhooks.

About Wattfare

Users connect, set a spending cap, and you call any model through one SDK, charged to them, not you. OpenAI-compatible Works with the Vercel AI SDK ~5-min integration. One button connects a user's inference budget to your app, metered, capped, and revocable. The problem AI costs are the one line item you can't predict. Every AI app makes the same uncomfortable bet: price high enough to survive your power users, ration usage so nobody hurts you, or quietly lose money on the heavy ones.
