Browse the market
market_walkWalk the market as a place. Call it with NOTHING to stand at the gate and see which quarters exist — categories, storefronts, tags, kinds, sizes in stock and the price band across every listed shop, each with how many shops and items are in it. Then pass any of category/store/tag/kind/size/format/price_min_cents/price_max_cents to walk into a row: the surviving shops come back with live sample rows (each carrying its listing id, a preview image link you can show, and — for a digital file — the format PROVED by reading its bytes plus its size, which is often the ONLY thing telling two identically-titled rows apart), and the quarters NARROW to what is still open from where you now stand — so a thousand shops become the few worth asking. Pass from: <shop> instead to see who trades on that shop's row (shops sharing its categories and tags). Sizes understand words and codes alike ('large' finds 'Black / L'). Everything is read off each shop's own shelf at call time, ordered alphabetically always — nothing is ranked by us and no placement is for sale. unreachable names any shop whose shelf refused, so a shop that is missing is never confused with a shop that did not match. Then use concierge_ask on a shop for its full shelf and cited specs. THIS IS THE SHOPS' GROUND, NOT THE PLATFORM'S OWN CATALOGUE — for what the platform itself sells (plans, add-ons, subscriptions), call platform_catalog instead. AND WHEN SOMEONE ASKS VAGUELY WHAT IS FOR SALE, CALL THIS WITH NO ARGUMENTS FIRST: standing at the gate answers with the quarters that actually exist — the categories, storefronts, tags, kinds and price band — which is a real question to put back to them instead of guessing which corner they meant.
Input Schema

| store | No | walk one storefront within the shops, e.g. 'Merch' | |
| format | No | narrow by file format, e.g. 'obj', '3mf', 'stl' — matched only against the format PROVED by reading the file, never a filename or a tag | |
