Capabilities

Tools 14

check_availability

Real-time status for up to 50 SKUs: available (online and in the shop), available-in-store-only, reserved, sold, or invalid. The live source of truth; the catalog can lag a recent sale.

Discovered
get_buying_policy

What NOSTOS buys and declines, how cash and store-credit offers are calculated, bounty premiums, basket caps, the free shipping label threshold, and the trade-in process.

Discovered
get_condition_grading_rubric

The NOSTOS condition grading vocabulary and the criteria for each grade, with region-code meanings. Optionally filter to one department.

Discovered
get_credit_policy

How NOSTOS store credit works: the 15% uplift over cash, how it's earned, where it's spent (in person at the Duluth shop), and how long it lasts.

Discovered
get_item

Full details for one SKU: description, condition notes, price, region, image, a direct product URL, how to buy it (online or in the shop only), and real-time availability.

Discovered
get_return_policy

The NOSTOS return policy: 14 days from delivery; NOSTOS pays return shipping on misrepresented, non-working or transit-damaged items; change-of-mind returns accepted with the buyer paying return shipping; refund timing.

Discovered
get_shipping_estimate

The NOSTOS shipping policy for a destination country (US, Canada, or not-yet-active international): the US rates and free-shipping rule, Canada's flat rate, and the free prepaid trade-in label. Policy, not a live carrier rate.

Discovered
get_store_info

NOSTOS store information: address, hours, contact, mission, tagline, categories, area served, social links, and current online and storefront status.

Discovered
get_trade_in_offer_estimate

Cash and store-credit totals for up to 25 items someone wants to sell. Name each item, its platform and its condition; NOSTOS prices every line itself, reports any it isn't buying, and says whether the free prepaid label applies and whether the basket goes to a personal review. An estimate that saves nothing.

Discovered
list_departments

List the store departments currently in stock (e.g. 'VG - Software', 'Apparel'), each with a count of available items.

Discovered
list_platforms

List the console platforms currently in stock, each with a count of available items.

Discovered
list_recent_drops

List the most recently added in-stock items, newest first. The answer to what's new at NOSTOS.

Discovered
lookup_market_price

What NOSTOS would pay for one game or console, in cash and in store credit, by condition (loose, CIB, box and game, new), from NOSTOS's own pricing engine. Says when NOSTOS isn't buying a line, or prices it in person at the counter, and why. An estimate, not an offer.

Discovered
search_inventory

Search the live NOSTOS catalog of retro games, consoles, and vintage apparel. Free-text query (accents optional) plus platform, department, region, condition, and price filters. Returns items for sale online and in the Duluth shop, title matches first; each says how to buy it (howToBuy). Every item is individually graded.
