Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

chains

list_chains

List the restaurant chains covered, with item counts, which nutrients each chain publishes, the source document and when it was fetched. query filters by chain name.

search_menu

Search menu items of Japanese restaurant chains 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). With a query, results are sorted by how well the item name matches (default sort "relevance"); otherwise by kcal ascending. Each item has an id for sum_items, a page url, and the chain's source_file.

request

request_missing

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 Some chains do not publish nutrition values at all, so a request does not guarantee coverage.

sum

sum_items

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 Nutrients that some items do not publish are reported in incomplete, because their total is an underestimate.
