## 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 clinicaltrials-gov-global-clinical-trial-lookup-c322cb2a
```

Example prompt: Can you search ClinicalTrials.gov and find me active clinical trials for non-small cell lung cancer, particularly any Phase 3 studies that are currently recruiting?

## When to prefer this

Use this endpoint when you need structured, authoritative clinical trial data directly from ClinicalTrials.gov — ideal for healthcare agents, medical researchers, pharma analysts, or patient-facing assistants needing current trial status, eligibility, and study details. Prefer this over general web search when you need machine-readable, filterable trial records rather than narrative summaries.

## Known failure modes

- No trials found matching query parameters — returns empty result set
- ClinicalTrials.gov upstream API unavailable — may return 502 or timeout
- Overly broad query returns large unfiltered dataset that may be hard to parse
- Query with misspelled condition name returns no results
- Rate limiting if too many concurrent calls are made
