List the dining halls and their service periods for the day, with whether they are open now. openNow is evaluated at the current campus-local time. The entries are the halls and their service periods for the day. stale means a page was served from an expired cache entry; asOf is the age of the data. Cafes, markets, bakeries, grills, prices and meal plans are out of scope.

Get the menu of one dining hall: meals, stations and dishes. Dish rows are arrays: [name, traits, allergens, mhealthyTier, calories, servingSize, servingSizeGrams] plus nutrients named by include_nutrients (a get_menu row never carries carbonFootprint). traits are codes 1-6 (glutenfree, halal, kosher, spicy, vegan, vegetarian); allergens are codes; read the key block. mhealthyTier 1-5. Calories kcal. With no meal, the meal being served now is returned (or the next one if closed); the response says which and why. Date defaults to today; site publishes today-3..+14. stale means the data is from cache and may be slightly old, but is still the best available; asOf is the age. Re-call only if you need guaranteed-fresh data. Allergens advisory.

Filter dining hall menus by allergen, trait, nutrient density, carbon, calories, sodium and name. All params optional; no params lists every dish for the day. Allergens: alcohol, beef, coconut, eggs, fish, item-is-deep-fried, milk, oats, peanuts, pork, sesame-seed, shellfish, soy, tree-nuts, wheat_barley_rye. Traits: glutenfree, halal, kosher, spicy, vegan, vegetarian. min_mhealthy: keep tiers >= (1-5). max_carbon: keep tiers <= (1 low, 2 medium, 3 high). Untagged dropped by both. nutrients: range per nutrient, e.g. {"protein":{"min":20,"unit":"g"}}. query: case-insensitive substring. Rows are arrays: [hall, meal, station, name, traits, allergens, mhealthyTier] plus carbonFootprint when max_carbon or sort_by carbon, then calories, servingSize, servingSizeGrams, dates in a range, then nutrients named by include_nutrients. traits are codes 1-6; allergens are codes; read the key. Station codes in each row resolve via key.stations. Every row already includes calories, servingSize, and servingSizeGrams. Use include_nutrients to get full nutrition data in the same call - no need to call get_item_nutrition per dish. stale means the data is from cache and may be slightly old, but is still the best available; asOf is the age. Re-call only if you need guaranteed-fresh data. Allergens advisory.

List the canonical nutrient identifiers, their units, the alternative units a threshold may be written in, and the Daily Value basis of the published micronutrients. A constraint on a nutrient excludes the dishes that publish no value for it, and a value the site writes as "trace" or "< 1%" is missing rather than zero. sortFields includes servingSize, mhealthyTier and ratio syntax "a:b".

Get the service periods published for a dining hall on the requested day, plus the regular weekly schedule. Accepts one hall, a list, or none for all (like filter_dishes). today is the day's published service periods and regular is the weekly schedule. A hall that cannot be read is reported in the failures and the other halls are still returned. The response carries the weekday name of the requested date. stale means the data is from cache and may be slightly old, but is still the best available; asOf is the age. Re-call only if you need guaranteed-fresh data.

The dining halls that are serving at the given time of day, and the ids of the ones that are not, with the service periods of the day for the halls that are open. Without arguments the current campus-local time is used, and the response says which time it resolved. open carries the hall details and today's periods; closed carries hall ids only. stale means a page was served from an expired cache entry; asOf is the age of the data.

Get the full nutrition panel of one dish. Name matched case-insensitively; exact match wins, else unique substring. Dish row uses the same coded layout as the sweep tools. Panel values are numbers with one units map; micronutrient amount is the derived amount, with the published percent behind it. asOf data age. Allergens advisory. Use this only when you need the full panel for a single dish. For multiple dishes, use filter_dishes with include_nutrients instead.
