This file is generated by API Evangelist from the public Heartflow surface and from the artifacts in this repository. Heartflow does not publish an llms.txt of its own (https://www.heartflow.com/llms.txt returns 404). ## What an agent can and cannot do here Heartflow operates a real production API, but it is not a public developer surface. - API host: https://api.heartflow.net — live, Django REST Framework, fully authenticated. Every route answers 403 with {"detail":"Authentication credentials were not provided."}. - Interactive reference: /swagger/ and /redoc/ are mounted on the API host but return 403. - Documentation host: https://docs.heartflow.net — behind a CloudFront signed-cookie gate (403 MissingKey on every path), so the reference is customer-only. - There is no published OpenAPI, no GraphQL endpoint, no AsyncAPI, no MCP server, no A2A agent card, and no /.well-known/ document on any Heartflow host. - There is no self-serve signup and no published pricing. Access is arranged through an institutional contract; https://app.heartflow.net/ is a login for existing customers. An agent cannot integrate with Heartflow from public information alone. The correct next step is https://www.heartflow.com/about/contact/ or the Heartflow One support desk. ## Platform - [Heartflow One](https://www.heartflow.com/heartflow-one/): the platform — CCTA is sent to Heartflow, analyzed, and the results are delivered back into hospital PACS and EMR. - [Roadmap Analysis](https://www.heartflow.com/heartflow-one/roadmap/): consistent CCTA reading and early CAD detection. - [FFRct Analysis](https://www.heartflow.com/heartflow-one/ffrct-analysis/): blood-flow assessment across the coronary tree to determine revascularization benefit. - [Plaque Analysis](https://www.heartflow.com/heartflow-one/plaque/): quantifies and characterizes plaque. - [Plaque Staging](https://www.heartflow.com/heartflow-one/plaque-staging/): risk stratification on total plaque volume. - [PCI Navigator](https://www.heartflow.com/heartflow-one/pci-navigator/): CT-guided intervention planning on a patient-specific 3D model. ## Support and access - [Heartflow One Support](https://www.heartflow.com/heartflow-one/support/): deployment, system configuration, and integration with PACS, EMR and other IT solutions. - [Contact](https://www.heartflow.com/about/contact/) - [Login](https://app.heartflow.net/) - [Indications for use](https://www.heartflow.com/indications/) ## Security and compliance - [Trust Center](https://security.heartflow.com/) — SafeBase.
