post/mercari/v1/search1 credit

Search Mercari Japan by keyword and by any combination of category, brand, seller, price range, condition, colour, shipping terms and shipping prefecture, paginated. Every row carries the item id and url, the title, the price as a number in JPY, whether it is still on sale or already sold, the condition grade, the category id, the seller's id and profile url, the image, and when it was listed and last touched. Filter on `status: sold_out` to get the prices items actually sold at - the comparables a resale valuation is built from. Paginate by passing back the `next_page_token` from the previous response.
