How this service works

ClinicalTrials.gov intelligence — search 400K+ trials by condition, intervention, sponsor, or phase. Full trial details, eligibility, outcomes, and aggregate stats. Pay-per-request via x402 on Base mainnet.

Output

Returns aggregate counts of clinical trials for the specified condition, broken down by trial status (e.g. recruiting, completed, terminated), trial phase (e.g. Phase 1, Phase 2, Phase 3), and a ranked list of the most active sponsors conducting trials for that condition.

Example use cases

Example prompt

“Give me a statistical overview of all ClinicalTrials.gov trials for Type 2 Diabetes — I want counts broken down by status (recruiting, completed, etc.), phase, and a list of the top sponsors.”

Endpoint

When to prefer

Use this endpoint when you need a high-level statistical summary of clinical trial activity for a condition rather than details about individual trials. Ideal for dashboards, competitive landscape analysis, research trend monitoring, or quick answers about how much research is happening in a given disease area. Prefer this over the search or detail endpoints when you don't need trial-level data.

Side effects

Unknown or misspelled condition name returns empty results or error
ClinicalTrials.gov upstream unavailability causes timeout or 503
Payment not processed (x402 payment required before data is returned)
Rate limiting if too many requests are made in quick succession
