Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

GovAuctions.app is a free public site where people search live government surplus auctions (vehicles, equipment, electronics, seized property) and check what comparable lots actually sold for before bidding. This server exposes that same data to code: live listings, sold-price comps, price trends, and the Flip Score resale signal.

search_listings — Search live GSA listings
Advertised by the server during the last successful anonymous check.
Advertised read-only

Search live GSA federal-surplus auction listings (facts only — no images). Filter by state, category, keyword, price, or distance from a US ZIP code. Works signed out (up to 25 rows per page). Raw listings cover sanctioned federal sources; sold-price comps span the full market.

get_sold_comps — Sold-price comps
Advertised by the server during the last successful anonymous check.
Advertised read-only

Sold-price comps for a described item, computed across the full government-surplus market in any market listed in `country`. Signed out: coverage (how many comparable sales, confidence, a coarse price band) plus `categoryStats`, the 25th/median/75th percentile of every sale in the item's category (in `state` when it has enough sales). Signed in or with an API key: the 25th/median/75th percentile for this item itself. `liveListingsUrl` links to the live auctions for the same item. A miss says which kind it is: reason `insufficient_comps` (too few comparable sales yet) is worth retrying, reason `category_not_priceable` (real-estate) never is — that category cannot be priced from a title. A catch-all `category` such as `miscellaneous` is not refused: it is dropped and the item is priced on its title alone, with `requestedCategory` and `categoryDropped` echoed back — check the resolved `category` and `confidence` before trusting the range. `pricedAs`, when present, is what was actually priced: a spelling fix, or the listing title with its lot count, lot number or serial removed. When the `category` you sent holds nothing like the item and another category clearly does, the range comes from that one, with `requestedCategory` and `categoryOverridden` echoed back. A miss can still carry `categoryStats` when the item's category is clear, and `retryHint` when the query was a long listing title: retry with just the brand and model.

get_sold_comps_batch — Sold-price comps, many at once
Advertised by the server during the last successful anonymous check.
Advertised read-only

get_sold_comps for a list of items in one call. Each query is either a string ('2015 Ford F-150') or an object with its own q/category/country/state. Each item costs one valuation lookup, exactly as if sent alone; an item that comes back without a range is not charged. If the monthly allowance runs out part-way, the items already priced are returned and `batch.truncated` names the rest. Batch size is capped by plan (10 on the free allowance). Requires sign-in or an API key.

Advertised by the server during the last successful anonymous check.
Advertised read-only

GovAuctions Flip Score resale signal for one live lot, from any source, in any market with sold-price comps (valued against that market's comp archive): estimated value, effective bid, discount, and the link to the lot on its source site. Pass the lot id as it appears in a govauctions.app lot URL. Requires sign-in or an API key.

Advertised by the server during the last successful anonymous check.
Advertised read-only

The individual archived sales behind an item: title, final price, sale month and state, plus the range they produce. Use when you want the evidence rather than just the number. Query-anchored — describe an item; there is no way to list the archive. Requires sign-in or an API key.

get_price_trend — Price trend
Advertised by the server during the last successful anonymous check.
Advertised read-only

Month-by-month median sale price for an item, plus the first-to-last change — 'is this category softening?'. Computed from the same comps as get_sold_comps, so it never contradicts that range. Returns an empty series when too few months clear the sample threshold. Requires sign-in or an API key.

get_comp_coverage — Comp coverage
Advertised by the server during the last successful anonymous check.

How much sold-price data we hold per category for a market, and which categories can never be priced. Check this before building on the comps tools — it is the honest answer about what we cannot do. Works signed out.

get_api_usage — API usage
Advertised by the server during the last successful anonymous check.
Advertised read-only

This key's usage for the current month: total calls and the separate valuation allowance (which comps, sold history, trend and flip-score draw down), plus the reset date. Call it to pace a long run instead of hitting a 429 mid-task. Every other signed-in tool result already carries the same numbers in `_meta.usage`, so this is rarely needed. Free: it does not count against either allowance. Requires sign-in or an API key.
