Macaroon Network
POST https://api.macaroonnetwork.com/execute/clinical-trials-search-v1
Search live clinical trial records from ClinicalTrials.gov: status, phase, conditions, interventions, lead sponsor, eligibility (sex, age range, a short truncated criteria excerpt), and locations. The only source used is the U.S. National Library of Medicine's public ClinicalTrials.gov API v2, available at no charge. Full eligibility-criteria text, full descriptions, and investigator/recruitment contact details are never returned -- only source-linked, truncated summary metadata.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
