Pay-Per-Compute Medical AI for Agents

NEW: Machine Payment Protocol (MPP) Support

We now support MPP (mpp.dev) — the HTTP 402 standard for machine-to-machine payments. When your free tier runs out, our API returns a proper 402 with WWW-Authenticate challenge. Your agent pays inline and retries. No signup, no OAuth, no billing dashboards.

Payment Methods

1. MPP/Tempo — ~500ms finality, sub-cent fees, native stablecoins
2. Stripe — Credit card via checkout link
3. x402 — USDC on Base chain direct transfer
