• search_inventory read-only

  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.

  Parameters:

  • limit — integer — Max results to return. Default 10.
  • query — string — Free-text match across name, description, genre, and platform. All words must match.
  • region — string — Filter by exact region code, e.g. 'JP', 'US', 'PAL'.
  • maxPrice — number — Maximum price in USD.
  • minPrice — number — Minimum price in USD.
  • platform — string — Filter by platform (case-insensitive substring), e.g. 'Saturn', 'N64', 'Game Boy'.
  • condition — string — Filter by exact condition, e.g. 'Loose', 'CIB', 'New'.
  • department — string — Filter by department (substring), e.g. 'VG - Software', 'Apparel'.
  • onlineOnly — boolean — Only items that can be bought online. Default false: in-store-only items are included, each with its howToBuy.
  • includeSold — boolean — Include sold items too. Default false.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_return_policy read-only

• get_credit_policy read-only

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_shipping_estimate read-only

  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.

  Parameters:

  • destination_country (required) — string — Destination country: a code like 'US' or 'CA', or a name like 'Canada'.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• lookup_market_price read-only

  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.

  Parameters:

  • name (required) — string — Title to look up, e.g. 'Mario Kart 64'.
  • platform — string — Platform hint to disambiguate, e.g. 'N64', 'Saturn'.
  • condition — string — Optional condition to focus the result on. 'boxgame' is Box & Game (No Manual).

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_trade_in_offer_estimate read-only

  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.

  Parameters:

  • items (required) — array — Up to 25 items to sell. NOSTOS prices each one itself; there is no price to pass in.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no
