    request_paymentRequest the user's approval to pay for a purchase. Usually returns `{auto_approved: false, approval_url}` — show the approval_url to the user so they can review the total and approve with one tap, then call get_payment_result. If the user's spending policy auto-approves this purchase (e.g. under their cap at an allowlisted merchant), it returns `{auto_approved: true, status: "approved", card}` immediately — no approval needed, just use the card. Args: amount: Total to charge, in major units (e.g. 18.50 dollars). merchant: Human-readable merchant / store name shown on the approval screen. line_items: Optional list of {"name": str, "quantity": int, "amount_cents": int}. currency: ISO currency code, default "usd".
    get_payment_resultPoll for the outcome of a payment request. Long-polls up to wait_seconds. Returns status one of: pending, approved, settled, declined, expired, not_found, claim_pending. When approved, includes a single-use `card` (number, cvc, exp) locked to this purchase — use it to complete checkout at the merchant. If still "pending"/"claim_pending", call again. For a claim (charge_id = the "clm_…" poll_id from request_payment): pass the agent_secret you received. The first approved result also contains `connect_token` — persist it and send it as the Authorization bearer on all future calls.
    list_payment_requestsList this agent's payment requests and whether each has been approved yet. Use this to see the state of every request you've made — not just poll one saved charge_id. Each item includes its `status` (pending, approved, settled, declined, expired) so you can tell which are still waiting and which the user has acted on. For a pending request it also returns the `approval_url` (re-surface it to the user); once a request is approved, call get_payment_result(charge_id) to fetch the card. Args: status: which to return — "open" (default, still-pending only) or "all". limit: max requests to return (default 20, capped at 100), newest first.
    record_orderReport the merchant's order reference back after checkout, so the user can later reverse (refund) the purchase. `order_ref` is the merchant's payment id (e.g. a Stripe PaymentIntent).
    request_subscriptionSet up a recurring subscription mandate (e.g. Netflix at up to $16/month). Requires the user's explicit one-time approval — returns an approval_url. The mandate is merchant-locked and capped: the merchant can never charge more than `cap` per period, and the user can cancel anytime (after which the merchant can never charge again). Args: merchant: merchant to authorize (e.g. "Netflix"). cap: max amount per period in major units (e.g. 16.00). interval: "weekly" | "monthly" | "yearly".
    list_subscriptionsList the user's subscription mandates and their status.
    cancel_subscriptionCancel a subscription mandate. Safe — canceling never spends money, and the merchant can never charge again afterwards.
