## 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 agentrxi-clinical-trials-search-508b35c3
```

Example prompt: Can you find currently recruiting clinical trials for non-small cell lung cancer in Texas? Show me up to 10 results with their phase, sponsor, and enrollment info.

## When to prefer this

Use this endpoint when an agent or user needs to discover, filter, or summarize clinical trials from ClinicalTrials.gov without building a direct API integration. It is ideal for patient research, competitive pharmaceutical intelligence, or medical literature support where trial status, phase, and sponsor data are needed quickly. Prefer this over direct ClinicalTrials.gov API calls when operating within a paid-per-call x402 agent workflow that already uses AgentRXI services.

## Known failure modes

- No trials found for the given query — returns empty list
- Invalid status filter value (e.g. misspelled enum) — may return error or unfiltered results
- Overly broad query returning too many low-relevance results — use limit parameter to cap
- ClinicalTrials.gov upstream unavailability causing timeout or error
- Location filter may not match all geographic formats consistently

## 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

Returns a list of matching clinical trials, each including the trial name, NCT identifier, current status (e.g. RECRUITING, COMPLETED), phase, sponsor, interventions being studied, enrollment count, and a direct link to the ClinicalTrials.gov study page.
