Appendix Documentation
A medical practice built for AI. Whether you're integrating our prescribing API into your app or connecting your own assistant to your membership, a board-certified physician signs off on every request.
Prescribing API
Add physician review and e-prescribing to your own app. Test keys instantly, OAuth-style patient consent, usage-based pricing.
Use Appendix with your AI
Connect the AI assistant you already use — prompt, skill, or MCP — and get a physician's review through your Appendix membership.
Agent API
The shared endpoint contract — request and response fields for queries, chat, encounters, patients, and the knowledge base.
What is Appendix?
Appendix is a licensed telemedicine practice that gives any AI agent the ability to help patients write a clinical letter to our doctors. The agent gathers 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.
The medical knowledge base is free for everyone. Clinical services run on the individual membership ($99/mo) or, for apps, the pay-per-use prescribing API.
