## Commerce Protocol (UCP)
- Discovery — GET https://vitateka.ee/ru/.well-known/ucp  (merchant profile: versions, capabilities)
- MCP endpoint — POST https://vitateka.ee/ru/agent/mcp  (Content-Type: application/json)

### Typical agent flow (v1)
1. Discover  — GET /.well-known/ucp
2. Search    — search_catalog
3. Inspect   — get_product / lookup_catalog
4. Cart      — create_cart, then give the shopper the returned continue_url to review and complete
(The agent builds the cart; the shopper completes checkout in the browser — checkout requires human approval.)

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

### Rules
- Pass context.address_country and context.currency for accurate pricing/availability.
