# Commerce interfaces

Current capability and authentication authority: https://branddesign.host/commerce/v1/manifest. Public discovery projection: https://branddesign.ltd/.well-known/agent-commerce.json. Read the live manifest before selecting a transaction interface.

MCP endpoint: https://branddesign.ltd/mcp. Resource metadata: https://branddesign.ltd/.well-known/oauth-protected-resource. The documented tools are catalog, manifest, register_agent, create_order, accept_offer, start_payment, order_status, kya_challenge, kya_verify and kya_status. OAuth scopes separate commerce.read, commerce.order and commerce.pay. An import does not establish a connection or issue credentials.

For raw HTTP authentication, exact request signing, order/acceptance/status/payment bodies, DNS KYA and supported payment routes, read AGENTS.md and the live manifest. The complete transactional OpenAPI schema is https://branddesign.host/commerce/v1/openapi.json. The LTD website OpenAPI describes read-only discovery. Direct HTTP create requests require idempotencyKey plus payload; MCP tools have separate input schemas. CLI and WebMCP are read-only. Available ACP and UCP profiles are documented there. An implemented adapter does not establish platform admission or an independently verified purchase through that adapter.
