Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_lease | Where a lease stands: awaiting_payment, in_review (paid, a person checks it first), live, refused (nothing charged), rejected_refunded, refunded (the slot was taken while paying), expired (the link ran out unpaid) or ended, with a plain message. | Read-only |
| find_windows | List the free ad windows on the tower and the free city billboards, with monthly prices. Tower windows come first (floor 1 up, the cheapest floors first), then billboards (the most prominent first): use kind to get only one of them, and maxPrice to cap the monthly price. Any floor, face or spot filter returns tower windows only. Pages hold up to 100 items; when next isn't null, pass it as cursor for the next page. | Read-only |
| get_prices | Every floor's monthly price for a middle and a corner window, and the price range of city billboards, in US cents. The listed price is exactly what Stripe charges. | Read-only |
| get_window | One window or billboard by id ("F47-S3" is floor 47, south face, column 3; "B-1234" is a city billboard): its monthly price and whether it can be leased now. When it can't, reason says why: taken (lit by a brand), reserved (paid, in review), paused, prize (a game prize, only its winner can lease it) or crown (never sold). | Read-only |
| start_lease | Start leasing a free window or billboard for a brand. The ad (website, name, pitch, logo) is checked first; a refused ad costs nothing. Returns checkoutUrl and leaseId: give checkoutUrl to the person, who pays the monthly price on Stripe within 60 minutes (you can't pay for them, and nothing is charged before they do). No account is needed: the window belongs to the email they pay with. Name, pitch and logo come from the website when left out. Then follow the lease with check_lease. | Changes data |
