# Subscribe (mock agent checkout)

No real payment is processed. This walks an agent through the 4-step agentic
commerce flow.

## The 4 steps

1. **Read offers** — `GET /pricing` or `GET /pricing.md` or `GET /api/v1/pricing`.
2. **Subscribe** — `POST /api/v1/agent/subscribe` (optionally with
   `Idempotency-Key`). Returns a scoped demo key and the MCP endpoint.
3. **Use the key** — send `Authorization: Bearer sa_demo_...` to read paid
   articles and connect MCP.
4. **Connect MCP** — `POST /mcp` JSON-RPC; tools respect your tier.

## Roadmap

This mock stands in for real agentic commerce: x402 payment, ACP, AP2, and
Stripe agentic checkout. The shape of the flow is what matters for the demo.
