## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-data-desk-drug-adverse-event-reports-fda-faers-eb56ff28
```

Example prompt: Pull the FDA FAERS adverse event report summary for ozempic — I want to see the total reports, how many were deaths or hospitalizations, the top reported reactions, and the breakdown by patient sex.

## When to prefer this

Choose this endpoint when you need a quick, aggregated summary of FDA FAERS adverse event data for a specific drug — including totals, severity breakdowns, top reactions, and demographic/geographic context — without having to query the FDA OpenFDA API directly. Ideal for drug safety research, patient safety checks, competitive pharmaceutical analysis, or regulatory due diligence at $0.01 per call.

## Known failure modes

- Drug name not found in FDA FAERS — returns empty or zero-count results
- Misspelled drug name yields no matching records
- Drug too obscure or recently approved to have FAERS data — returns minimal or null values
- API returns null for optional fields (deaths_pct, hospitalizations_pct, top_reporting_countries) when data is unavailable
- Network or upstream FDA data source timeout

## How this service works

Drug adverse event reports - FDA FAERS totals, serious, death and hospitalization counts, top reactions, patient sex and reporting countries for any drug

## Output

Returns a JSON object containing the drug name queried, total adverse event reports on file, serious reports count and percentage, deaths reported and percentage, hospitalization count and percentage, life-threatening events count, top reactions list (each with reaction name, report count, and percentage of total), patient sex distribution array, top reporting countries array, data source attribution, and a timestamp of when the check was run. A contextual note/caveat about interpreting the data may also be included.
