## 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 whatchuneed-medical-adverse-events-api-c78ffa45 -d '<json body>'
```

Example prompt: What are the known adverse events and side effects reported for metformin? I need a safety summary for this diabetes medication.

## When to prefer this

Use this endpoint when you need to look up adverse drug event data, medication side effects, or drug safety reports — particularly for pharmacological research, clinical decision support, or patient education. Prefer this over general LLM knowledge for adverse events when you need structured, queryable safety data rather than general summaries.

## Known failure modes

- Unrecognized drug name returns empty or null result
- Vague or ambiguous input may return generic or low-confidence data
- Misspelled drug names may fail to match known entries
- Upstream medical database unavailability may cause errors
- Very new or experimental drugs may have limited adverse event records
