## 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 medical-device-adverse-events-lookup-0c5f7a33
```

Example prompt: Can you pull up the adverse event reports for pacemakers? I want to see what safety issues have been flagged for that device.

## When to prefer this

Use this endpoint when you need structured adverse event data for a specific medical device brand or generic device category, particularly in healthcare safety research, regulatory compliance, or litigation support contexts where per-query micropayment billing via USDC is acceptable.

## Known failure modes

- Missing 'brand' query parameter returns an error or empty result
- Unknown or misspelled device name may return empty results
- Payment failure via x402 protocol blocks the request entirely
- Rate limiting or server error returns non-200 response
- Malformed query string causes input validation failure

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a 'result' field containing adverse event records for the queried medical device brand or generic device type, along with a 'success' boolean indicating whether the lookup completed successfully.
