api record

Underpriced AI prices secondhand items for resellers from real eBay sold listings. Use price_item when a user asks what something is worth or would sell for; give it a photo URL when one exists (marks, sizes and condition are read from the photo) and the description otherwise. Pass the user's cost to get a worth-it verdict. If the user uploaded a photo you cannot pass as a URL, describe it precisely in description: brand, model number, size, marks, condition and what is included; that is what the price rests on. Use get_sold_comps when the user wants the recent sales themselves for a specific…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • price_item unknown never probed

    What a secondhand item sells for on eBay US: a calibrated estimate with a range, the recent real sold comps behind it, three list prices (fast, market, patient) with the 14-day sell chance, the net after eBay fees, and a worth-it verdict when you pass what the user would pay. Give image_url (a public https link to a photo) whenever one exists; a description alone works but reads less.

  • get_sold_comps unknown never probed

    The most recent real eBay US sales for a search query (brand, model or pattern, a few specific words), with the count, median and quartiles. Use when the user wants to see what actually sold and for how much.

  • worth_it unknown never probed

    Net after eBay fees and a verdict (worth it / thin / pass) for an expected sale price and what the user would pay. Pure arithmetic; use price_item first when the sale price is unknown.

    {
  "type": "object",

  • buy_credits unknown never probed

    Ways to pay for Underpriced AI scans. Without a choice it lists the credit packs (credits never expire), pay as you go ($0.25 per photo scan on a monthly bill, no cap), and for a signed-in user their balance. With a pack it returns a Stripe Checkout link for that user; with PAY_AS_YOU_GO it returns the link that puts a card on file so scans just run from then on. Anonymous callers get the pricing page link.

    }
  }
}
    arguments 16 lines
  • get_scan_result unknown never probed

    For a signed-in user: the finished result for a scan on their account, in the same shape as price_item, once the sold comps have landed in the background. Call it with the account.scanId a photo price returned when that result said comps were still loading (about 20 seconds later), or to re-read any saved scan.

      "type": "string",
      "maxLength": 200,
      "minLength": 8,

    arguments 21 lines
  • list_on_ebay unknown never probed

    For a signed-in user: turns a photo scan from price_item (account.scanId) into an inventory item with a draft eBay listing on their Underpriced AI account (title, list price defaulting to the market price, condition, description) and returns the link where they review and publish it in the app, plus whether eBay is connected and the connect link if not. It never publishes anything; publishing happens in the app after the user checks the listing.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
