Try the Goldin categories API

Goldin's full filter-enum surface for goldin-search, scoped to one lot pool -- category, sub_category, certification, item_type, and the live auction list (each with its own id, name, and current lot count), plus the sort enum valid for that pool. category/sub_category/certification/item_type are read live from Goldin's own current inventory, not a fixed taxonomy, so results can shift over time. The Auction pool (default) and the Fixed Price "Private Sales" marketplace are disjoint item pools with different certification/item_type values and different sort enums -- pass the same auction_type here and to goldin-search.

Response behavior

- `category`, `sub_category`, `certification`, and `item_type` are read live from Goldin's own current inventory, not a fixed taxonomy — the exact set of values can shift over time as new lots are listed, and differs between the two pools (e.g. `WATA`, `AFA`, and `VGA` certifications and item types like `VHS and Betamax` and `Carded Figures` exist only under `auction_type=Fixed_Price`). - `sort` for `auction_type=Auction` (default): `Featured` (default — despite its UI label "Lowest Lot #"), `Ending_Soonest`, `Highest_Bids`, `Lowest_Bids`, `Most_Bids`, `Least_Bids`, `Most_Recent_Bids`, `Highest_Lot_Number`, `Recently_Started`. - `sort` for `auction_type=Fixed_Price`: `Recently_Created` (default), `Highest_Bids`, `Lowest_Bids` — a smaller, non-overlapping enum, since fixed-price listings have no lot number or bid count to sort by. Example response (`auction_type=Auction`, the default): ```json { "code": 200, "msg": "OK", "data": { "auction_type": "Auction", "category": ["Sport", "Non-Sport", "Oscar Alley Collection"], "sub_category": ["Baseball", "Basketball", "Football"], "certification": ["PSA", "Ungraded", "Beckett", "Other", "CGC", "SGC", "AMG", "JSA", "Multiple"], "item_type": ["Single Cards", "Memorabilia", "Cases/Boxes/Packs"], "auctions": [ { "id": "202605-0515-1956-e34eb08d-dad8-4f5d-8e0e-23494bffa363", "name": "2026 Monthly Sports Elite #8", "lot_count": 1519 } ], "sort": ["Featured", "Ending_Soonest", "Highest_Bids", "Lowest_Bids", "Most_Bids", "Least_Bids", "Most_Recent_Bids", "Highest_Lot_Number", "Recently_Started"] } } ``` Example response (`auction_type=Fixed_Price`): ```json { "code": 200, "msg": "OK", "data": { "auction_type": "Fixed_Price", "category": ["Non-Sport", "Sport"], "sub_category": ["Pop Culture/Entertainment", "Baseball", "Basketball"], "certification": ["Ungraded", "Other", "PSA", "CGC", "WATA", "AMG", "AFA", "Beckett", "Multiple", "VGA"], "item_type": ["Art", "Video Games", "Music", "Single Cards", "Toys", "VHS and Betamax"], "auctions": [ { "id": "fixed_price_marketplace", "name": "Marketplace", "lot_count": 148 } ], "sort": ["Recently_Created", "Highest_Bids", "Lowest_Bids"] } } ```
