Two modes

Top reactions (summary) - the best starting point. For each drug, a ranked list of the most reported reactions with how many reports mention each and its share of the drug's reports:

{ "drugs": ["OZEMPIC"], "mode": "reactions", "topReactions": 25 }

Example output: nausea, vomiting, diarrhoea, decreased appetite... each with a report count.

Individual reports - one row per adverse-event report, with:

the reactions reported and their outcome (recovered, fatal, ongoing...)
seriousness (death, hospitalization, disability, life-threatening)
patient sex and age, reporter type (physician, pharmacist, consumer...)
country and the other drugs listed in the same report
the FDA report ID

Filters

seriousOnly - only serious events
country - events in one country (US, GB, CA...)
sinceYear - only reports from a year onward

Who uses this

Pharma, biotech and medical-device companies: pharmacovigilance and competitive safety monitoring - what is being reported about a drug and its competitors.
Researchers and universities: study real-world drug safety signals with structured data.
Health, legal and insurance analysts: assess reported harm and outcomes for a drug.
Journalists and patient advocates: see what the FDA's reporting system actually contains.

Important context

Source: FDA FAERS via openFDA (public US government data). Reports are voluntary and unverified - an adverse event report does not mean the drug caused the effect, and counts are influenced by how widely a drug is used and reported. This data supports signal-spotting, not conclusions about causation or safety.
The keyless openFDA limit is 1,000 requests/day per IP (shared here). Add your own free openFDA API key to raise it to 120,000/day; it stays private to your run.

Pricing

A small fee per row. Unknown drugs and requests blocked by the daily limit are free note rows, and the first 2 rows of every run are free.
