Each result has the exact price Buy a card charges, plus the $1 fee. Dutch auctions and your own listings are left out. Page while `has_more` is true; page 20 is the last. `truncated: true` means the search stopped at its scan ceiling with matches unread. To get past either, narrow the price range: `min_price` at the last result's price (`max_price` for `price_desc`). Results at exactly that price come back again, so skip the ones you have. ## OpenAPI ````yaml /partner-api/openapi.yaml get /api/partner/v1/marketplace/listings openapi: 3.1.0 info: title: CatchBack Partner API version: 1.0.0 summary: Open packs, trade cards, read card data and ship vaulted cards. description: >- The Partner API acts on one CatchBack account with its real CatchCoins balance. Several operations here move money or data, so read [Idempotency](/partner-api/idempotency) before you call them. Error bodies are JSON with a human-readable `error` and, where you might branch on it, a machine-readable `code`. Branch on the status and the `code`, because the `error` text can change.
