# Appendix

> Appendix connects the AI agent you already use with a human doctor. Built by an ER doctor and staffed by board-certified physicians, Appendix provides medical review, guidance, and prescriptions when appropriate. Use it for your own care with a $49/month membership, add family members for $19/month each, or bring the same doctors into your app through the Prescribing API.

## For Developers — Prescribing API

- **What it is**: `POST https://api.appendix.com/api/v1/prescribing/query` submits a clinical request on behalf of your user; a board-certified U.S. physician reviews it and e-prescribes when medically appropriate. Appendix is the medical practice — you don't need to build one.
- **Pricing**: outcome-based — you pay per completed physician review (complete and incomplete reviews are priced differently). No platform fees, no per-prescription charges. Current rates: https://appendix.com/docs/prescribing-api/pricing. Volume pricing available (hello@appendix.com).
- **Consent model**: your user approves each request through an OAuth-style consent page hosted by Appendix, consents to care with Appendix, and verifies identity. Enterprise option: organizations that obtain and document patient consent directly can create patients via API and skip the consent page — requires an enterprise agreement (hello@appendix.com). Details: https://appendix.com/docs/prescribing-api/external-consent
- **Outcomes**: signed webhooks (HMAC-SHA256) plus a polling endpoint report status, prescription count, and whether a physician message is waiting — never clinical details. Apps whose use case requires it can opt into full data visibility: the patient explicitly consents to the app seeing the interaction (demographics, physician conversation, prescription details), retrievable via a details endpoint; the webhook stays thin either way. Details: https://appendix.com/docs/prescribing-api/webhooks
- **Sandbox**: instant self-serve test keys with simulated decisions; production keys after review.
