Clinical Trials Database

Gives you command-line access to ClinicalTrials.gov's REST API v2 without wrestling with raw queries. The Python script comes with dedicated flags for the filters you actually care about: trial phase, age groups, recruitment status, interventions, sponsors. Built by Google DeepMind's science team, which suggests it's meant for serious research workflows rather than casual lookups. Requires uv for Python environment management and makes you acknowledge ClinicalTrials.gov's terms on first run. If you're building agents that need to pull trial data or doing meta-analysis work, this beats hitting the API directly. The 2.4K stars on the parent repo indicate it's seeing real use in research contexts.

Overview

Access worldwide clinical trial data from ClinicalTrials.gov via the REST API v2. The CLI script at scripts/clinical_trials_api.py wraps the API with dedicated flags for common filters (phase, age group, status, intervention, sponsor, etc.) so you rarely need to construct raw queries.
