What this endpoint does
Adverse Events lives at animalandveterinary/event.json. Veterinary drug adverse event reports. openFDA returns everything as JSON with a meta block (hit counts, disclaimers) and a results array.
Who uses it
Veterinary researchers and pet-health startups use these reports to spot patterns in animal drug reactions. Reporter type (vet vs owner) is often searchable.
Example request
Paste this into a browser or our Explorer (swap the search term as needed):
GET https://api.fda.gov/animalandveterinary/event.json?search=primary_reporter:veterinarian&limit=5You should see JSON with meta.results.total telling you how many matches exist.
Searching the data
Start with search=primary_reporter:veterinarian in our Explorer or your own HTTP client. Each endpoint documents its own field list on open.fda.gov. Common knobs: limit (how many rows), skip (offset for paging), sort (field:asc or field:desc), and count (aggregate unique values).
Tips that save time
Wrap exact phrases in quotes inside the search parameter. Use count=field.exact when you want top values instead of raw rows.
