IMPORTANT — no public API. As of 2026-09-12, GNC Holdings publishes **no public developer program,
no API documentation, no machine-readable contract (OpenAPI / AsyncAPI / GraphQL / gRPC / WSDL),
no MCP server and no A2A agent card**. `api.gnc.com` and `developer.gnc.com` do not resolve; the
full `/.well-known/` discovery surface, `/apis.json`, `/openapi.json` and `/llms.txt` return 404 on
every host GNC operates. Its storefront runs on Salesforce Commerce Cloud (Demandware) and its
store locator on Yext, but neither vendor contract is published by GNC for third-party use.
