## Developer surface — what does not exist

No OpenAPI, Swagger, GraphQL SDL, AsyncAPI, Postman collection, SDK, CLI, webhook catalog, MCP server, or A2A agent card is published on any Diligent Pharma host. `api.diligentpharma.com`, `docs.diligentpharma.com` and `developer.diligentpharma.com` do not resolve. `360.diligentpharma.com` is a single-page application that answers HTTP 200 with an HTML shell for every path, including `/openapi.json` and `/.well-known/agent-card.json` — those 200s are not documents. The only machine-readable documents on any Diligent Pharma host are the OAuth 2.0 / OpenID Connect discovery documents at `clerk.diligentpharma.com`, which govern application sign-in, not a developer API.
