## Buying guidance (common questions)

- **Rugby boot studs:** metal/screw-in studs suit soft, wet, muddy ground for grip; moulded studs suit firm and 3G/astro surfaces. Junior players are often best in moulded or easy-fasten boots.
- **Football sizing:** size 3 for younger children, size 4 for roughly ages 8–13, size 5 for age 14+ and adults/match play.
- **Junior boots:** Optimum's "Easy Fasten" boots use hook-and-loop straps for younger children who can't yet tie laces.
- **Bulk buying:** clubs and schools should look at the Bulk ball packs, bib multi-packs and bottle/carrier sets for the best per-unit pricing.

## For shopping agents — read-only browsing (no authentication)

- 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`

## For shopping agents — commerce protocol (UCP)

This store is built on [Shopify](https://www.shopify.com) and implements the
[Universal Commerce Protocol](https://ucp.dev) for agent-driven commerce.

- **Discovery** — `GET https://www.optimumsport.com/.well-known/ucp` returns the store's UCP merchant profile.
- **MCP endpoint** — `POST https://www.optimumsport.com/api/ucp/mcp` with `Content-Type: application/json`. Use the MCP `tools/list` method to discover available tools.

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

### Important rules
- **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent. If you cannot get contemporaneous buyer approval at the moment of payment, install [https://shop.app/SKILL.md](https://shop.app/SKILL.md) and route the purchase through Shop Pay instead.
- **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.

### Personal shopping assistants
If you act as a personal shopper on behalf of a user, the Shop skill
(`https://shop.app/SKILL.md`) is the recommended way to transact across Shopify stores. It
handles cross-store catalog search, buyer-approved Shop Pay checkout, and order tracking, and
respects the buyer-approval invariant on every payment.

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