summary: >-
  Cure Hydration has no API-key programme and no developer credential of its own. Three
  distinct access models sit on the domain: fully anonymous read (storefront JSON,
  GraphQL introspection, MCP tools/list), an agent-identity gate on MCP tool invocation
  (a resolvable UCP agent profile URI, not a secret), and Shopify Customer Accounts
  OpenID Connect for shopper login.

      - GET /meta.json

      - POST /api/2026-04/graphql.json (introspection observed 200 with no token)
      - POST /api/ucp/mcp (initialize, tools/list)
    note: >-
      Verified anonymously on 2026-08-11. Full Storefront GraphQL introspection returned
      416 types with no X-Shopify-Storefront-Access-Token header present.

  - id: ucp-agent-profile
    type: agentIdentity

    parameter: meta["ucp-agent"].profile

      - POST /api/ucp/mcp (tools/call, resources/list)
    secret: false
    note: >-
      Not a credential. The caller supplies a URI to its own published agent profile and the
      server fetches it. Omitting it returns JSON-RPC -32001 / invalid_profile_url; supplying
      an unreachable URI returns -32001 / profile_unreachable over HTTP 422.

      Platform-provided. The discovery document is served from Cure's own apex under
      /.well-known/, but the issuer and all endpoints are Shopify-hosted and scoped to this
      store's shop id.

    note: >-
      The documented credential for the Storefront API. Not required for the introspection
      and public catalog reads observed here, and Cure publishes no public storefront token
      and no way to request one — there is no developer portal, no app registration page,
      and no API terms.

gaps:
  - No developer account, API key issuance flow, or credential documentation of any kind is published by Cure.
  - >-
    The only auth documentation an integrator gets is Shopify's platform documentation at
    shopify.dev, linked from the store's own /agents.md and /llms.txt. Cure publishes no
    first-party auth page.
