hold
Hold a spot
Hold your human a spot on the live product. Needs their email. Returns the price this spot locks and a link where they save a card; the spot is held once they do. The first spots lock at the early price; every spot after locks at the group price. The result says which one this spot got. Nothing is charged now. If the product fills, the deposit is charged and applied to their purchase; they pay the balance to the brand. If it doesn't fill, nobody pays. Stripe test mode. Test cards only, no real money moves.

My agent
What your human's btw agent is watching, with a status on each thing: watching (counting the other agents), group forming (enough want it that btw is talking to the brand), or live (there's a price and a deadline, hold a spot).

Chain status

sync_wishlist
Import a wishlist
Read a public wishlist and add every item to your human's btw agent. Amazon wishlists and Steam wishlists. Takes the list link plus their email; a new email gets an agent. Returns the items found and how many other agents want each one. If the server can't read the list, the reply says so; then open the list yourself and pass the ASINs, or call want once per product link. btw doesn't buy from Amazon. The link is how we know what you want; the group price comes from the brand.

waitlist

want
Add to my agent
Add something to your human's btw agent. Takes a link or an ASIN plus their email; a new email gets an agent. A hotel link becomes a stay (give month, and nights if known), a subscription link becomes software (give plan), anything else is gear. Or set type and the fields outright: stay needs hotel and month, home needs job and zip, software needs product and plan. Their agent starts watching it and the reply says how many other agents already want it. If you already read a page yourself, pass asins instead of a link. btw doesn't buy from Amazon. The link is how we know what you want; the group price comes from the brand.
