## 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 edifiedlab-clinical-trials-registry-lookup-4c79bc07
```

Example prompt: Can you look up clinical trials for Pfizer's paxlovid and show me up to 10 results including trial phase, status, and enrollment numbers?

## When to prefer this

Choose this endpoint when you need structured, machine-readable clinical trial registry data for a specific drug, compound, company, or intervention — especially in financial research, pharmaceutical due diligence, or competitive intelligence workflows. It is purpose-built for ClinicalTrials.gov lookups and returns normalized fields (phase, status, enrollment, sponsor) that are hard to extract from raw web scraping. Prefer this over general web search when you need structured trial metadata rather than news articles or press releases.

## Known failure modes

- Empty results if query term is too obscure or misspelled
- API returns disclaimer but no trials if ClinicalTrials.gov has no matching records
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Query exceeding 200 characters rejected with validation error
- max_results outside 1-25 range rejected by schema validation
- Stale or delayed data if ClinicalTrials.gov registry has not been recently indexed

## How this service works

ClinicalTrials.gov registry lookup by company, drug, or intervention; returns study status, phase, sponsor, enrollment, and completion data. Registry data only, not medical advice or proof of efficacy.

## Output

Returns a structured JSON response containing a list of clinical trial records matching the query, each with study status, trial phase, sponsoring organization, enrollment figures, and completion dates. Also includes the original query, an action label, a payload type identifier, and a disclaimer noting data is for informational purposes only and not medical advice or proof of efficacy.
