## 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 2s-io-070b75e2
```

Example prompt: Pull up the latest FDA adverse event reports for dogs that were given Bravecto and showed vomiting reactions — give me up to 50 records.

## When to prefer this

Use this endpoint when you need US FDA-sourced, public-domain veterinary adverse event data filterable by drug, species, or reaction. Prefer it over general web search when you need structured, VeDDRA-coded pharmacovigilance records for veterinary safety research, pet food adverse events, or livestock drug surveillance.

## Known failure modes

- No matching records returned when filters are too narrow or drug/reaction name doesn't match OpenFDA's terminology
- Invalid species name returns empty results or an error
- Limit parameter out of range (must be 1–100) returns a validation error
- OpenFDA upstream downtime causes request failure or timeout
- Drug substring too short (< 2 chars) or too long (> 100 chars) rejected by schema validation

## How this service works

FDA animal and veterinary adverse event reports, newest first. All filters optional. Each record includes AER ID, dates, animal species/gender/breed/age/weight, reactions (VeDDRA-coded), drugs (brand + active ingredients + administration), primary reporter (Veterinarian/Owner/Other). Use cases: veterinary practice safety research, pet food adverse events, livestock drug surveillance. Backed by OpenFDA's /animalandveterinary/event endpoint; public-domain US government records.

## Output

A list of FDA veterinary adverse event records (newest first), each containing the AER ID, report dates, animal details (species, gender, breed, age, weight), VeDDRA-coded reactions, drug information (brand name, active ingredients, administration route), and the primary reporter type (Veterinarian, Owner, or Other).
