### Tool changes

- 2026-10-17 `list_on_ebay` changed (description, inputSchema)
  - before: 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 (connecting brings them back to the same item). It never publishes anything and only prepares eBay; publishing happens in the app after the user checks the listing, and until then the draft shows on the Sell tab under Not live yet.
  - after: 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 (connecting brings them back to the same item). If the item already has an unpublished eBay draft, it returns that draft unchanged and never overwrites it (draftKept); changes are made in the app. It never publishes anything and only prepares eBay; publishing happens in the app after the user checks the listing, and until then the draft shows on the Sell tab under Not live yet.
- 2026-10-15 `get_sold_comps` changed (description, inputSchema)
  - before: The most recent real eBay US sales (sold comps) 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.
  - after: The most recent real eBay US sales (sold comps) 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. One search runs: the query as typed (a retail price with "$" in it is left out), with model or part_number appended only when the query does not already name it; with no query, brand plus model, or brand plus part_number.

  - before: Ways to pay for Underpriced AI scans. Without a choice it lists the credit packs (5 to 250 scans, from $3; credits never expire) and, for a signed-in user, their balance. PACK_5, PACK_15 and PACK_30 can be bought here: with one it returns a Stripe Checkout link for that user. PAY_AS_YOU_GO is only for a signed-in plan subscriber whose plan scans run out (top-up scans, 25 cents each past the plan); it is listed only when the account can use it. Larger packs and monthly plans (whose unused scans carry over one month) are on the pricing page. Anonymous callers get the pricing page link.

PACK_5, PACK_15 and PACK_30 can be bought here: with one it returns a Stripe Checkout link for that user. PAY_AS_YOU_GO turns on the meter for a signed-in account: 25 cents for each photo pricing, billed monthly to the card on file; pay per answer with no plan needed, or the top-up past the plan's scans for a plan subscriber. Larger packs and monthly plans (whose unused scans carry over one month) are on the pricing page. Anonymous callers get the pricing page link.

## Tools (6)

- `buy_credits`: Ways to pay for Underpriced AI scans. Without a choice it lists the credit packs (5 to 250 scans, from $3; credits never expire) and, for a signed-in user, their balance. PACK_5, PACK_15 and PACK_30 can be bought here: with one it returns a Stripe Checkout link for that user.

Larger packs and monthly plans (whose unused scans carry over one month) are on the pricing page. Anonymous callers get the pricing page link.
- `get_scan_result`: 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.
- `get_sold_comps`: The most recent real eBay US sales (sold comps) 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. One search runs: the query as typed (a retail price with "$" in it is left out), with model or part_number appended only when the query does not already name it; with no query, brand plus model, or brand plus part_number.
- `list_on_ebay`: 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 (connecting brings them back to the same item).

- `price_item`: What a secondhand item sells for on eBay: a calibrated estimate with a range, the recent real eBay sales behind it (sold comps, linked where the source gives a link), three list prices (fast, market, patient) with the 14-day sell chance, what the seller keeps after eBay fees, and a worth-it verdict when you pass what the user would pay. Description prices are eBay US in USD. A photo price (image_url, a public https link) needs the user signed in through the connector: it runs a real scan on their account, priced in their own eBay marketplace and currency (price.currency). Without sign-in, describe the item; a description works but reads less than a photo.
- `worth_it`: What the seller keeps after eBay fees and a verdict (worth it / thin / pass) for an expected sale price and what the user would pay. Pure arithmetic in USD; use price_item first when the sale price is unknown.
