402 Mcp

Gives Claude the ability to pay for and consume Lightning-gated APIs autonomously. It discovers services via Nostr (kind 31402 events), probes endpoints for pricing without paying, then auto-pays invoices using NWC or Cashu if under your configured budget cap. Credentials are cached locally and encrypted. Works with any L402-compliant server including toll-booth and Aperture. The agent can browse volume discount tiers, reason about cost versus usage, and make purchasing decisions within your spend limits. Supports onion routing and Handshake domains with fallback. Useful when you want Claude to consume paid data APIs, routing services, or AI inference endpoints without manual API key management or per-service registration.
