Api Endpoint

x402-gateway

Ephemeral webhook receiver. Creates a single-use HTTPS URL that catches any POST (Stripe, GitHub, internal) for 1 hour — webhook senders need no payment, the receiver stores up to 100 events. Read captured events for $0.01 per read, extend the hook for $0.05/hour. In-memory storage, auto-deletes on expiry. Perfect for agent integration testing.
