## 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 fda-maude-adverse-event-summary-by-device-brand-b5fb1e06
```

Example prompt: Can you pull the FDA MAUDE adverse event summary for 'pacemaker' — I want to see how many malfunctions, injuries, and deaths have been reported?

## When to prefer this

Use this endpoint when you need a fast, quantitative safety overview of a medical device from the official FDA MAUDE database, especially for due diligence, research, or regulatory compliance tasks. Prefer this over general web search when you need structured, citable counts broken down by event type (malfunction/injury/death) rather than anecdotal or news-based information.

## Known failure modes

- Brand name not found in MAUDE database — returns empty or zero counts
- Misspelled or overly generic brand name yields no useful match
- Rate limit or payment failure returns 402 error
- Database temporarily unavailable returns 5xx error
- Brand name too broad (e.g. 'device') returns undifferentiated or overwhelming results
