Example use cases
Finding trials for rare disease patients
“Can you search clinical trials for Duchenne muscular dystrophy and show me the trial name, sponsor, and current status?”
Researcher scoping treatment landscape
“Look up active clinical trials for type 2 diabetes and return the phase and primary outcome fields so I can see what treatments are being studied.”
Healthcare app enriching condition pages
“Pull clinical trial data for 'Alzheimer's disease' and give me the name and price_usd fields — I want to show users what studies are available for this condition.”

Endpoint
GEThttps://workspace-x402-paywall.onrender.com/health/trials?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight pay-per-call access to clinical trial data without a subscription, especially for sporadic queries. It is ideal for agents that need occasional trial lookups and want to pay fractions of a cent per call via USDC on Base or Solana. Prefer alternatives (ClinicalTrials.gov API, OpenFDA) for high-volume or free access needs.

- No matching trials for obscure or misspelled condition returns empty results
- Payment failure (insufficient USDC balance) returns HTTP 402
- Service unavailable on Render free tier returns 503 during cold start
