## API surface

Paige markets **UnifAI** — an SDK plus a set of APIs for vendor-neutral integration of AI applications
into laboratory digital-pathology workflows, and the mechanism behind the Paige AppLab marketplace.
**That developer surface is not publicly documented.** As of 2026-08-04:

- `docs.paige.ai` is CNAMEd to ReadMe.io but returns Cloudflare error 1014 for every path.
- `api.paige.ai`, `developer.paige.ai`, `platform.paige.ai` and `unifai.paige.ai` do not resolve.
- `app.paige.ai` is the customer application login; it is a single-page app whose catch-all route
  answers 200 with an HTML shell for every path, including `/openapi.json` and `/graphql`.

No OpenAPI, AsyncAPI, GraphQL SDL, MCP manifest or A2A agent card is publicly retrievable. Integration
access goes through a laboratory customer relationship — https://www.paige.ai/request-a-trial
