How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
A JSON object containing a total count of matching clinical trials and an array of trial records, each with an NCT ID (e.g. NCT01234567), trial phase (e.g. PHASE3), recruitment status (e.g. RECRUITING), and sponsor name.
Example use cases
Recruiting trials for patient matching
“Find all clinical trials that are currently recruiting for Phase 3 studies — I need the NCT IDs, sponsors, and statuses to match patients to open trials.”
Pharma competitive intelligence
“Pull a list of active clinical trials and tell me which sponsors have the most recruiting Phase 2 and Phase 3 studies right now.”
Medical research overview dashboard
“Get me the total count of clinical trials and a sample list with their phases and statuses so I can populate my research dashboard.”

Endpoint
GEThttps://api.polyform.org/v1/health/clinical-trials?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to clinical trial data without registering for an API key or managing credentials — ideal for AI agents that can handle x402 USDC micropayments on Base. Prefer this over direct ClinicalTrials.gov API calls when you want a simple, pay-per-call model with no account setup.
Side effects

- Empty results array if no trials match the given query parameters
- Malformed query parameters may return a 400 Bad Request
- Rate limiting or network errors may return 5xx responses
- Stale data if underlying ClinicalTrials.gov data has not been refreshed recently
