}About the opendays.com API
The opendays.com API provides structured access to UK university and college open day data across 5 endpoints, covering calendar listings, event details, institution profiles, and directory search. The get_calendar endpoint returns day-by-day open day schedules for any given month, while get_open_day_detail delivers per-event fields including date, time, location, description, and booking URL — all keyed by event slug.
Calendar and Event Data
The get_calendar endpoint accepts optional year and month parameters (e.g. month=september, year=2025) and returns an array of days, each containing a date string and an events array. Each event object includes the institution name, a URL, a slug, and a location string. Omitting both parameters returns the current month's schedule. Slugs from calendar results feed directly into get_open_day_detail, which returns the full event record: title, date, time, location, description, institution, and a booking_url pointing to the institution's registration page.
Institution Directory
list_all_institutions returns the complete directory as an array of objects, each with name, slug, and url. The response includes a count field showing the total number of institutions indexed. search_institutions accepts a query string and performs a case-insensitive substring match against institution names, returning the same shape — useful for resolving a partial name to a slug before fetching the full profile.
Institution Profiles
get_institution_profile takes an institution slug and returns a structured profile containing name, address, website, campuses (array of name/address pairs), and a contact object with name, department, telephone, and email fields. It also exposes three URL fields — travel_url, booking_url, and open_days_url — linking directly to the institution's own pages. Coverage is limited to UK higher education institutions listed on opendays.com.

Does opendays.com have an official developer API?+
What does `get_open_day_detail` return beyond the calendar listing?+
get_open_day_detail adds the event title, time, a full description string, and a booking_url — the direct link to register for that specific event. The time and location fields may be empty strings if the institution hasn't specified them.Does the API cover open days outside the United Kingdom?+
Can I filter calendar results by institution type, subject area, or region?+
get_calendar returns all scheduled events for the requested month without server-side filtering by institution type, subject, or location. The location field is present in each event object, so client-side filtering by location string is possible. You can fork this API on Parse and revise it to add a filtered endpoint if you need region- or subject-scoped results.Are past open day events accessible, or only future ones?+
get_calendar accepts any valid year and month combination, so historically listed months are queryable in the same format as future ones. However, booking_url values in get_open_day_detail for past events may point to expired or inactive registration pages on the institution's own site — the API returns whatever URL is present in the source listing.
