GET https://api.fda.gov/tobacco/researchdigitalads.json?search=_exists_:uuid&limit=5You should see JSON with meta.results.total telling you how many matches exist.
Searching the data
Start with search=_exists_:uuid 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
Run a tiny limit=3 query first and read one full record before scaling up. Register a free API key if you plan to automate requests — it raises rate limits.
