## Docs

- [Get your profile](https://docs.hi-doctor.ai/api-reference/account/get-your-profile.md): The authenticated patient's own profile.
- [List profiles](https://docs.hi-doctor.ai/api-reference/account/list-profiles.md): Self-scoped.
- [Refresh the access token](https://docs.hi-doctor.ai/api-reference/account/refresh-the-access-token.md): Exchange a valid `refresh` token for a new `access` token. Access tokens are short-lived; refresh rather than storing the password.
- [Register a new patient](https://docs.hi-doctor.ai/api-reference/account/register-a-new-patient.md): Starts a signup and emails a one-time code. Returns **200, not 201** — no account exists yet; the registration is held pending until the code is verified.
- [Request a password reset](https://docs.hi-doctor.ai/api-reference/account/request-a-password-reset.md): Emails a reset link. Unauthenticated. Use this for an account created with Google sign-in that needs a password before it can use `/v1/users/token/`.
- [Set a new password](https://docs.hi-doctor.ai/api-reference/account/set-a-new-password.md): Consumes the token from the reset email. Unauthenticated — the token is the credential.
- [Sign in](https://docs.hi-doctor.ai/api-reference/account/sign-in.md): Exchange an email and password for an `access` and `refresh` token pair.
- [Sign in with Google](https://docs.hi-doctor.ai/api-reference/account/sign-in-with-google.md): Sign in or sign up with a Google credential.
- [Update profile](https://docs.hi-doctor.ai/api-reference/account/update-profile.md): Self-scoped partial update.
- [Update your profile](https://docs.hi-doctor.ai/api-reference/account/update-your-profile.md): Partial update. Checkout requires a complete profile: if it refuses with `PROFILE_INCOMPLETE`, the response lists `missing_fields` — fill those and retry. The patient must be 18 or over and resident in a supported country.
- [Verify the emailed code](https://docs.hi-doctor.ai/api-reference/account/verify-the-emailed-code.md): Consumes the one-time code from registration and activates the account. **The account cannot sign in until this succeeds** and there is no resend endpoint — to get a fresh code, register again with the same address.
- [Authentication](https://docs.hi-doctor.ai/api-reference/authentication.md): Sign in with email and password, then call any patient endpoint with a bearer token.
- [Cancel at the end of the period](https://docs.hi-doctor.ai/api-reference/billing/cancel-at-the-end-of-the-period.md): Schedules cancellation for the **end of the current paid period** — never immediately. Access continues until that date and can be undone with reactivate. Refused while an early-order lock is in place.
- [Check a checkout session](https://docs.hi-doctor.ai/api-reference/billing/check-a-checkout-session.md): Returns the state of a Stripe checkout session. A paid session may finalise and create its consultation as a side effect of this call.
- [Get your subscription](https://docs.hi-doctor.ai/api-reference/billing/get-your-subscription.md): The authenticated patient's current plan, including `current_period_end` and whether a cancellation is already scheduled.
- [Open the Stripe billing portal](https://docs.hi-doctor.ai/api-reference/billing/open-the-stripe-billing-portal.md): Returns a Stripe-hosted URL where the patient changes card, plan or billing address. Hi-Doctor never sees card details.
- [Pull the next renewal forward](https://docs.hi-doctor.ai/api-reference/billing/pull-the-next-renewal-forward.md): Creates the renewal consultation now instead of at the period end.
- [Start checkout](https://docs.hi-doctor.ai/api-reference/billing/start-checkout.md): Creates a Stripe checkout session for a treatment, or returns an existing consultation already covered by an active plan. Refuses with `PROFILE_INCOMPLETE` if the profile is missing required fields.
- [Undo a scheduled cancellation](https://docs.hi-doctor.ai/api-reference/billing/undo-a-scheduled-cancellation.md): Cancels a pending period-end cancellation so the plan keeps renewing. Returns `409 already_active` if nothing was scheduled.
- [Get one consultation](https://docs.hi-doctor.ai/api-reference/consultations/get-one-consultation.md): A single consultation belonging to the authenticated patient.

- [Log a weight for a day](https://docs.hi-doctor.ai/api-reference/progress/log-a-weight-for-a-day.md): **Upserts by `logged_on`** — one entry per day, so logging again for the same date replaces it.
- [Log an injection](https://docs.hi-doctor.ai/api-reference/progress/log-an-injection.md): **Appends** — unlike weight, every call creates a separate entry, including for the same day. `injected_at` is required and must carry its UTC offset.
