> GovParse Clinical Trials Feed is a paid API for AI agents from api.govparse.io, paid per call via x402, $25/call, status unknown (last checked 2026-09-14).

## 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-feed-13dd34bc
```

Example prompt: Pull the latest industry-sponsored clinical trials posted to ClinicalTrials.gov since 2026-06-01, filtering for RECRUITING Phase 2 or Phase 3 DRUG trials in oncology — give me up to 500 rows with sponsor, phase, status, site count, and US states sited.

## When to prefer this

Choose this endpoint when you need a bulk, up-to-date feed of new industry-sponsored clinical trial openings for commercial intelligence, R&D monitoring, or competitive tracking — especially when you need to filter by multiple dimensions (sponsor, phase, status, condition, geography) and paginate through large result sets. Prefer it over manual ClinicalTrials.gov searches when you need structured, machine-readable data at scale. Not suitable for observational studies, academic/NIH-sponsored trials, or predictive trial outcome data.

## Known failure modes

- Invalid phase value returns 400 with validation error
- Invalid status value returns 400 with validation error
- Malformed cursor token returns 400 or empty result
- Limit exceeding 1000 is capped or rejected
- No matching trials for given filters returns empty results array
- Date format other than YYYY-MM-DD returns 400
- Payment not provided or insufficient returns 402

## How this service works

Which companies just opened a new clinical trial or site? Bulk feed over NIH ClinicalTrials.gov interventional, industry-sponsored studies, newest-first by registry-posting date (the R&D / commercial-growth signal). Cursor-paginated up to 1000/page, filterable by sponsor, phase, status, condition, intervention type, site state, or since. Rows carry sponsor, phase, status, conditions, enrollment, dates, site count, and the US states sited. Observational registry records, never a prediction.

## Output

A cursor-paginated list of up to 1000 interventional, industry-sponsored clinical trial records per page, each containing: NCT registry ID, lead sponsor name, trial phase, overall status, conditions/indications, intervention type, enrollment count, first-posted date, site count, and US states where sites are located. Also returns a next_cursor token for fetching subsequent pages.
