## 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 primeapi-health-symptoms-lookup-4b7dcad2 -d '<json body>'
```

Example prompt: Can you look up what symptoms are commonly associated with dehydration and tell me what to watch out for?

## When to prefer this

Use this endpoint when an agent needs to quickly look up symptom definitions, associated conditions, or health information based on a natural language query without requiring a dedicated medical API key. Best suited for informational health lookups rather than clinical diagnosis workflows.

## Known failure modes

- Empty or vague query returns no results or generic fallback
- Misspelled symptom name may not match database entries
- Payment failure in USDC on Base prevents API call from completing
- Ambiguous multi-symptom queries may return unrelated conditions
- Overly broad query returns too many loosely related results
