## 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 clearcheck-hospital-quality-profile-ff964f49
```

Example prompt: What's the CMS star rating and quality profile for Mayo Clinic in Rochester, Minnesota — specifically how they compare to the national average on mortality, safety, and readmissions?

## When to prefer this

Use this endpoint when you need CMS-sourced quality data for a specific US hospital, including star ratings and comparative mortality/safety/readmission statistics. Prefer this over generic hospital directory lookups when the user's question involves quality, safety benchmarks, or national comparisons. Best for healthcare decision-support, provider research, or compliance/referral workflows.

## Known failure modes

- No hospital found matching the given name/city/state — returns empty hospitals array
- Ambiguous name matches multiple hospitals — returns list for disambiguation
- Hospital not yet rated by CMS — missing or null overallRating
- State code invalid — query returns no results
- Limit parameter ignored if too large — defaults to 5

## How this service works

CMS star rating and quality profile for a US hospital: mortality, safety and readmission versus the national average.

## Output

Returns a best-match hospital record and a list of matching hospitals, each with: CMS overall star rating, address, phone, county, ownership type, emergency services flag, CMS facility ID, and a breakdown of how many quality measures (safety, mortality, readmission) are better or worse than the national average. Also includes a verdict string and reasons array summarizing the quality assessment.
