Clinical trials search: ClinicalTrials.gov studies

$0.01 per call · failed calls are never charged · no account or API key needed

Search ClinicalTrials.gov studies by condition, intervention or any words, optionally only recruiting ones: NCT id, title, status, phase, conditions, interventions, sponsor, enrollment, start and completion dates, number of locations and countries, and a link. From the ClinicalTrials.gov API (US National Library of Medicine). Information only, not medical advice. Use to find trials for a condition or drug.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/gov/clinical-trials?condition=type%201%20diabetes"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/gov/clinical-trials?condition=type%201%20diabetes&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
