`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 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. It searches the signed-in user's own eBay marketplace (eBay UK in GBP for a UK seller), eBay US in USD when nobody is signed in, or the site given in marketplace; the result names the site (marketplace) and the currency (currency). 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. Sales whose title shows a different item are left out of the count, median and quartiles: comps.matched is how many were kept, comps.dropped how many were left out, and comps.relevanceChecked is false when that check could not run (every sale is then kept). comps.countIsLowerBound true means eBay returned a full page, so the count is that many or more. include words must all appear in a sale's title (and are added to the search when missing); a title with any exclude word is left out; both match whole words in any case and are named in the answer. prefer words leave nothing out: sales whose title has every one are listed first (preferred true) and summarized in comps.preferred, while count and summary still cover every matching sale. Each listed sale has condition, saleType, bids, shipping and location, each null when not known (a sale stored before 22 October 2026 gives condition only as new or used). exclude_items leaves out sales by eBay item number (each listed sale's itemId), before every other filter; comps.removedByItems counts them. limit sets how many recent sales are listed (default 8, up to 50).

`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). 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 in the app under Sell, Not live yet.

`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. A description price searches the signed-in user's own eBay marketplace (eBay UK in GBP for a UK seller), eBay US in USD when nobody is signed in, or the site given in marketplace; price.currency names the currency. A photo price (photo, a file the user uploaded in the chat, or 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 the currency you give it, with eBay US fees: pass the sale price and the cost in the same currency (the one price_item named in price.currency). For a seller on eBay UK, the worthIt block price_item returns already uses their own fees. Use price_item first when the sale price is unknown.
