## 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 citiview-clinical-trials-search-4f7bd2d4
```

Example prompt: Can you find recruiting clinical trials for type 2 diabetes — I'm interested in studies in California, and show me up to 10 results?

## When to prefer this

Choose this endpoint when an agent needs structured, real-time clinical trial data from ClinicalTrials.gov — including status, phase, sponsor, and enrollment details — especially when filtering by recruitment status or geographic location. Prefer this over general web search when you need machine-readable trial metadata rather than prose summaries, and over academic paper search when the goal is finding active or completed trials rather than published research results.

## Known failure modes

- No trials found for the given query (empty result set)
- Invalid or unsupported status filter value causing query error
- Location string not recognized, returning unfiltered or empty results
- Network timeout or upstream ClinicalTrials.gov API unavailability
- Missing required 'q' parameter returns a 400 error

## How this service works

Clinical trials search (ClinicalTrials.gov): studies for a condition, drug or keyword with status, phase, sponsor, interventions, enrollment and links. Filter by status and location.

## Output

A list of clinical trial records from ClinicalTrials.gov, each including the study title, current status (e.g. RECRUITING, COMPLETED), phase, sponsor name, interventions being studied, enrollment count, and a direct link to the full trial listing.
