YAB-E

Find deals whose price drops on its own, make an offer, or let Muse wait and buy when the price hits your number.

YAB-E is a marketplace where prices move. Sellers set a normal price and a private minimum, and the price can drop when it is quiet or a date gets close. With this app, Muse can search offers, read today's price for every week or item, buy at today's price, make an offer, or set your own price and wait. Muse never pays for you: every purchase ends in a Stripe link you open yourself, and a waiting order only charges your card when the price reaches your number. Demo sellers answer as a dry run, so you can try it with nothing charged.

Try asking Muse: "Find me a week at a lake cabin on YAB-E and wait until it is $1,500."

New to Muse?Muse is Meta's AI assistant. YAB-E is an app you add to it, and once it is on, you can ask Muse to do this for you: find deals whose price drops on its own, make an offer, or let muse wait and buy when the price hits your number. It takes about two minutes and you can turn it off any time.

Is it safe to connect?

What Muse can see: Nothing in your accounts. It sees the offers on YAB-E and the email you give it for a purchase. Payment happens on Stripe, never inside Muse.

Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

Who runs it: the team behind this site.

Also use it in ChatGPT or Claude

YAB-E is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.

Add it to ChatGPT
  1. 1

    Open ChatGPT settings

    In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).

  2. 2

    Turn on developer mode

    Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

  3. 3

    Create the connector

    Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.

  4. 4

    Use it in a chat

    Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.

Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Add it to Claude
  1. 1

    Open Claude settings

    In Claude, open Settings, then Connectors.

  2. 2

    Add a custom connector

    Choose Add custom connector, give it a name, and paste the link.

  3. 3

    Connect and use it

    If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.

Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Tools · 7

search_offersFind offers on YAB-E. Returns each offer's id, seller, price today (or list price for make-an-offer sellers) and which actions work. Prices never go above the seller's normal price.
get_offerFull details for one offer: today's price for every week or item, what's left, how prices move, and which action to use.
buy_nowBuy at today's price. Returns a Stripe checkout link that the buyer opens and pays themselves. For weekly offers, pass the week's start date; the week is held for 30 minutes.
wait_for_priceSet the buyer's own price and let Yabby wait. Returns a link where the buyer saves their card with Stripe and confirms. Then Yabby buys automatically the moment the price reaches their number. Tell the buyer about the automatic charge first.
make_offerOffer a price to a make-an-offer seller. If the seller accepts on the spot you get a Stripe checkout link for the buyer to open and pay; otherwise the seller replies to the buyer by email.
ask_shopFor a shop that is NOT on YAB-E: ask it to sell an item at the buyer's price. Nothing is charged. The buyer first confirms by email, then gets a ready message and link to send the shop themselves. If the shop accepts, YAB-E arranges payment with both sides.
check_statusCheck a purchase, offer or waiting price by the reference from an earlier result and the buyer's email.
