## API surface

Philo has no developer-facing API. The following was observed on 2026-08-05:

- [Product GraphQL endpoint](https://www.philo.com/graphql): live (Apollo Server, returns
  JSON), but **introspection is disabled** (`GRAPHQL_VALIDATION_FAILED`) and it is
  undocumented. It is the private backend for Philo's own web/mobile/CTV clients, not a
  published API.
- No OpenAPI, Swagger, AsyncAPI, JSON Schema, Postman collection, MCP server or A2A agent
  card was found on any Philo host.
