Japan Restaurant Calories

Search menu items of Japanese restaurant chains and stores, and packaged foods of Japanese food makers, and get their nutrition facts. Queries that return no results are counted anonymously (the query text and chain only) to decide which chains to add. query matches item name, size, category, genre and chain name (Japanese; spaces mean AND; katakana/hiragana and full/half width are treated alike; common chain nicknames like ケンタ, マック, サイゼ work). Combine with chain / genre / kcal range. Use nutrient to find items rich in a nutrient (only chains that publish it). Default order: with nutrient, by that nutrient descending; else with a query, by how well the item name matches ("relevance"); otherwise by kcal ascending. total includes discontinued items (listed last), so it can be larger than item_count in list_chains. Each item has an id for sum_items, a page url, and the chain's source_file.

Add up nutrition for a set of items (a meal, a day) using ids from search_menu. Nutrients that some items do not publish are reported in incomplete, because their total is an underestimate.

List the restaurant chains, stores and packaged-food makers covered (makers have type: packaged_food_maker), with item counts (current items only), which nutrients each chain publishes and when the data was fetched. query filters by chain name and also returns each chain's source document URL.

Tell the site operator that a restaurant chain or menu item is missing. Use only after search_menu / list_chains could not find it AND the user actually wanted it. One request per chain or item. Only the chain, item and note are stored (no personal information is needed or kept). Requests are counted (not shown publicly) and used to decide what to add next. Some chains do not publish nutrition values at all, so a request does not guarantee coverage.
