Deprecated: This endpoint uses a legacy response format. Use the following collection-based endpoints instead, which return a cleaner response shape with structured price objects: GET /api/v2/listings/collection/{slug}/all for all listings in a collection, GET /api/v2/listings/collection/{slug}/best for best listings by price, or GET /api/v2/listings/collection/{slug}/nfts/{identifier}/best for the best listing on a specific NFT. To look up an individual order, use GET /api/v2/orders/chain/{chain}/protocol/{protocol_address}/{order_hash}. The collection-based endpoints return results sorted by best price. To query by creation time, use the events API (GET /api/v2/events). Note: the 'maker' filter on this endpoint has no equivalent on the collection-based endpoints. Also, the NFT-specific route (GET /api/v2/listings/collection/{slug}/nfts/{identifier}/best) only returns the best single listing, not a full paginated list.
