Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 govparse-clinical-trials-search-1687aca1
```

Example prompt: Find all recruiting Phase 3 drug trials sponsored by Regeneron that were first posted since January 2025, and show me up to 50 results sorted by start date descending.

## When to prefer this

Use this endpoint when you need structured, filterable access to industry-sponsored clinical trial data from ClinicalTrials.gov — especially for commercial use cases like CRO business development, trial software sales targeting, or competitive pipeline intelligence. Prefer this over raw ClinicalTrials.gov queries when you need sponsor entity resolution, clean filtering by phase/status/condition/state, and commercial-ready output. Not suited for academic trial design, patient recruitment, or non-industry-sponsored studies.

## Known failure modes

- No matching trials found for the given filters — returns empty result set
- Invalid phase or status enum value — returns 400 validation error
- Date string in wrong format — returns 400 parsing error
- Limit exceeds 100 cap — returns 400 or clamped result
- Entity UUID not found in resolved graph — no enrichment returned
- Rate limit or payment failure via x402 — returns 402 or 429

## How this service works

Which companies are running clinical trials, and at what stage? Search ClinicalTrials.gov interventional industry-sponsored studies by lead sponsor, phase, status, condition, intervention type, a US state with a site, first-posted date (since), start date, or completion date. Returns the sponsor (entity-resolved where possible), phase, status, conditions, enrollment, and dates — a developer target list for CRO, trial-software, and commercial-ops sellers. ClinicalTrials.gov public records.

## Output

Returns a paginated list of clinical trial records, each including the resolved sponsor name and optional entity UUID, trial phase, overall status, conditions studied, enrollment count, intervention types, first-posted date, start date, and completion date.
