Appendix Documentation

A medical practice built for AI agents. Your agent handles the intake, a real doctor signs off.

What is Appendix?

Appendix is a licensed telemedicine platform that gives any AI agent the ability to help patients write a clinical letter to our doctors. The agent gathers the patient's symptoms and medical history, assembles a structured clinical letter, and submits it for physician review. A board-certified physician personally reviews every submission and decides whether to issue a prescription.

No API key is required to begin. Just POST a clinical letter and get a checkout URL back.
