RelayStation is one primitive — a lease — wrapped in a few shortcuts. Pick the shortcut that fits, or configure your own. Your agent pays once at creation; the infrastructure runs on its own until expiry.
Your first lease in five minutes. A Storage example with the API-key and x402 wallet paths side by side.
Lease as the primitive. Handoff as the cross-cutting feature. Pricing, auth, errors — the shape of the API before the endpoints.
Storage is the configurable primitive. Mailbox and Checkpoint are opinionated shortcuts for common agent patterns.
Every endpoint, every parameter, every response code. Plus MCP wiring, x402 discovery, and the changelog.
