Prefer these endpoints over scraping the storefront: - UCP discovery: `GET https://fathead.com/.well-known/ucp` — supported versions, capabilities, and payment handlers. - MCP endpoint: `POST https://fathead.com/api/ucp/mcp` (`Content-Type: application/json`) — call `tools/list` to discover the available tools and their schemas. - Sitemap: https://fathead.com/sitemap.xml Typical flow: 1. **Discover** — `GET /.well-known/ucp` to confirm capabilities and supported versions. 2. **Search** — `search_catalog` to find products matching the buyer's intent. 3. **Cart** — `create_cart` to add the desired items. 4. **Checkout** — `create_checkout`, then `update_checkout` to set shipping address and method. 5. **Complete** — `complete_checkout` to finalize (the buyer must approve payment). Rules: - **Checkout requires human approval.** Never complete payment without explicit, contemporaneous buyer consent. - **Respect rate limits.** Back off on HTTP 429 responses. - **Pass buyer context** (`address_country`, `currency`) for accurate pricing and availability. ## Browse without an agent key Read-only access, no authentication required: - All products: `GET /collections/all` - Product page: `GET /products/{handle}` · JSON: `GET /products/{handle}.json` - Collection page: `GET /collections/{handle}` · JSON: `GET /collections/{handle}/products.json` - Search: `GET /search?q={query}&type=product` - Sitemap: `GET /sitemap.xml` ## Featured products - [Custom - Big Head - Foam Core Cutout](/products/custom-big-head-foam-core-cutout) — Get ready to make a statement with our Custom Big Head Foam Core Cutout!
