## 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-college-lookup-132b8d38
```

Example prompt: What's the full breakdown for Vanderbilt University — tuition, admission rate, graduation rate, typical debt, and median earnings 10 years out?

## When to prefer this

Use this endpoint when you need a fast, structured summary of a specific US college's cost, selectivity, size, and graduate outcomes in a single call. Prefer it over manual College Scorecard lookups when building agents that answer questions about higher education affordability, admissions, or ROI. It is best suited for named institution lookups rather than broad searches across many schools.

## Known failure modes

- Institution name not found — returns empty schools array or low-confidence matches
- Ambiguous name with multiple matches — returns top N results up to limit, no single bestMatch
- Missing scorecard data — some fields (e.g. admissionRatePct) may be null if the institution doesn't report
- State filter not applied correctly — omitting state for common names like 'Central University' may return unintended schools
- Service unavailable on Render cold start — may return 502 or timeout on first request after inactivity

## How this service works

College verdict: cost, size, admission rate, completion, median earnings and debt for a named US institution.

## Output

Returns a JSON object with a best-match school record and a list of matching schools. Each record includes institution name, city, state, control type (public/private), website, undergraduate enrollment, in-state and out-of-state tuition, average net price, admission rate, Pell grant rate, completion rate, median earnings 10 years after entry, median debt for completers, and a College Scorecard ID. Also includes a plain-text 'verdict' summarizing the institution's profile, and a 'reasons' array explaining the match.
