# Agent feed (decision log), newest first

  description: >-
    Backend for the Tozzecard app: card sign-in, card face and statement, agent
    strategy, portfolio, agent feed, market hours and the demo B402 merchant.


    **Sign in with the card key** (the EOA the browser unlocks with the
    passkey):

    1. `POST /auth/challenge {address}` → `{message}`

    2. `account.signMessage({ message })` (viem)

    3. `POST /auth/verify {message, signature}` → `{token, address, kyc, card}`.

    4. Send `Authorization: Bearer <token>` on `/me*`, `/kyc/session` and `PUT
    /strategy`. Tokens last 30 days.


    **Activating the card** (identity check with Didit): while `kyc` is not
    `approved`, `card` is null. `POST /kyc/session {returnUrl?}` → `{url}`; open
    it; Didit sends the user back to `returnUrl`; poll `GET /me` while `kyc` is
    `pending`. On approval the card is issued with the holder name from the
    document.


    **Paying a merchant order** (B402 / x402 v2): `GET
    /merchant/orders/{id}/pay` → 402 with `accepts[0]`; build and sign with
    `@tozzecard/binance/eip3009` (`transferAuthorization`, `signTypedData`,
    `paymentHeader`); `POST` the same URL with header `PAYMENT-SIGNATURE`. The
    receipt comes back in `PAYMENT-RESPONSE`.


    Errors are `{error, code?}`. Amounts in USD are numbers; on-chain amounts
    are decimal strings.
