clinicaltrials-database

You can retrieve clinical trial records by querying the ClinicalTrials.gov API v2 with specific NCT IDs, applying filters for phase or status to the search endpoint, and exporting the structured JSON response to CSV for patient matching.

Yes, filtering clinical trial search results by recruitment status and study phase is supported. You build parameterized requests to the API v2 search endpoint to narrow results by condition, intervention, status, and phase.

The best way to retrieve full clinical trial details using an NCT ID is to query the /studies/{NCT_ID} detail endpoint on ClinicalTrials.gov API v2, which returns the complete trial record for eligibility screening and analysis.

Yes, bulk export of trial datasets is supported by ClinicalTrials.gov API v2. You handle pagination and rate limits to retrieve multiple trial records, returning structured JSON or CSV files for downstream research and analysis.

When using requests for ClinicalTrials.gov API v2 pagination, limitations include manually handling rate limits and page tokens. You must build parameterized requests carefully to avoid hitting thresholds when retrieving large trial datasets.
