tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.

AUCTION mode (default) finds ending-soon auctions sitting under market; FIXED_PRICE mode finds mispriced Buy It Now listings that can be bought instantly.

querystringrequiredbuy_pricenumberrequiredfee_pctnumbershipping_costnumberhot_listThe current pre-scored steal list across tracked lanes (watches, sneakers, bags, jewelry, beauty, cards, coins, guitars, lego, golf, autoparts, tools): live auctions at least 45% under market plus mispriced Buy It Now listings, refreshed every 30 minutes. Fast cached read.
lanestringEach block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
