## Commerce Protocol (UCP)
This store implements the Universal Commerce Protocol (UCP) for agent-driven commerce.
- **Discovery** — `GET /.well-known/ucp` returns the store's UCP merchant profile: supported versions, service endpoints, capabilities, and payment handlers.
- **MCP endpoint** — `POST /api/ucp/mcp` with `Content-Type: application/json`. Use the MCP `tools/list` method to discover available tools and schemas.

### Typical Agent Flow
1. **Discover** — `GET /.well-known/ucp` to confirm capabilities
2. **Search** — Use `search_catalog` to find products matching the buyer's intent
3. **Cart** — Use `create_cart` to add desired items
4. **Checkout** — Use `create_checkout` to start the purchase flow
5. **Fulfill** — Use `update_checkout` to set shipping address and method
6. **Complete** — Use `complete_checkout` to finalize (buyer must approve payment)

### Supported UCP Versions
- `2026-04-08` (latest stable)
- `2026-01-23`

### Important Rules
- **Checkout requires human approval.** Agents must not complete payment without explicit, contemporaneous buyer consent.
- **Respect rate limits.** The MCP endpoint is rate-limited per IP. Back off on 429 responses.
- **Use buyer context.** Pass `context.address_country` and `context.currency` for accurate pricing and availability.

## Read-Only Browsing (No Authentication Required)
For agents that only need to read store data without transacting:

### Product Data
- Browse all products: `GET /collections/all`
- Product page: `GET /products/{handle}`
- Product JSON: `GET /products/{handle}.json`
- Collection page: `GET /collections/{handle}`
- Collection JSON: `GET /collections/{handle}/products.json`
- Search: `GET /search?q={query}&type=product`

### Store Metadata
- Sitemap: `GET /sitemap.xml`
- Agent discovery: this document (`/agents.md`) is the canonical agent-facing description of the store; `/llms.txt` mirrors it.
