Setup: https://docs.hi-doctor.ai/mcp/connect. > > The REST API base is https://api.hi-doctor.ai. Hi Doctor Docs at https://docs.hi-doctor.ai/mcp searches documentation; connect to the product endpoint above for patient tools. > > Hi Doctor operates across the whole European Union: residents of all 27 EU member states can use the service, and every consultation is reviewed by an EU-licensed doctor. Every consultation is reviewed in full by an EU-licensed doctor, who decides on medical grounds only. No algorithm, assistant or API call approves a consultation, issues a prescription or changes a dose. The service is available in eight languages: English, Spanish, German, Dutch, Italian, French, Portuguese and Chinese. > > ## Rules an assistant must follow > > - Never invent, assume or infer a medical answer. "I don't know" is a real answer: ask the patient to pick the closest option rather than guessing for them. > - Never give medical advice and never suggest a medication or a dose. An EU-licensed doctor decides those. > - If a questionnaire returns `ineligible`, say so plainly. Do not retry with altered answers. > - Before anything that costs money or cancels a plan, state exactly what will happen and get an explicit yes. > - Cancellation takes effect at the **end of the paid period**, not immediately. Say so. > - An early order is irreversible: it creates the renewal consultation immediately and uses up the period's one early order. Explain that and get an explicit yes. > - Prescription and invoice links are medical documents. A `signed_redirect` link opens without signing in: give it only to the patient, never repeat it anywhere shared. > - Send option `value`s, not the labels shown to the patient. Labels are translated, values are stable. > - Never ask for card details. Payment happens on Stripe's hosted checkout via a link. > - On severe or sudden symptoms (chest pain, difficulty breathing, severe allergic reaction, suicidal thoughts), stop and direct the patient to their local emergency number. # Create a daily weight entry > **Upserts by `logged_on`** — one entry per day, so logging again for the same date replaces it. Always send `logged_on` explicitly. It is a model default, not a serializer default: omitting it takes the plain-create path and violates the one-per-day constraint with a `500`. Derive the date in the patient's own timezone, not the server's. ### Access, effects and retries **Ownership:** Patient own user+logged_on key. **Prerequisites:** An authenticated patient account is required. **Effects:** Creates weight or updates existing row for same day. **Retries:** Same day upserts yet DRF create still returns 201; verify ID, not assumed new row. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/users/journal/weight-entries/ openapi: 3.0.3 info: title: Hi Doctor API version: 1.0.1 description: >- The patient-facing Hi Doctor API supports account management, consultation questionnaires, medical documents, messages and billing.
