How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with a count of matching trials and an array of trial objects, each containing: NCT ID, phase (e.g. PHASE2), title, study type (e.g. INTERVENTIONAL), lead sponsor name, and overall status (e.g. RECRUITING).
Example use cases
Finding recruiting trials for a condition
“Look up clinical trials that are currently recruiting for Type 2 diabetes — I want to see the phase, study type, and who the lead sponsor is for each one.”
Pharmaceutical competitive intelligence
“Can you fetch a list of clinical trials and find which sponsors are running Phase 2 or Phase 3 interventional studies right now? I want to map the competitive landscape for a new drug we're developing.”
Patient eligibility research
“My doctor mentioned I might qualify for a clinical trial. Can you search for currently recruiting interventional studies and show me the NCT IDs and titles so I can bring a list to my next appointment?”

Endpoint
GEThttps://anibalb.duckdns.org/x402/clinical-trials?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, pay-per-call access to clinical trial data without setting up API keys or accounts. It is ideal for agents needing to programmatically query ClinicalTrials.gov data via a micropayment model on Base using USDC. Prefer alternatives (direct ClinicalTrials.gov API) if you need advanced filtering, full trial details, or high-volume queries where per-call pricing becomes expensive.
Side effects
- Payment failure via x402 protocol returns 402 with payment instructions
- No trials found returns count:0 and empty trials array
- Network timeout if upstream ClinicalTrials.gov is slow
- Malformed query parameters may return empty or error response
- DuckDNS domain may have intermittent availability
