How this service works
Per-call clinical trial search, study dossiers, and change-deltas from ClinicalTrials.gov. Paid per call via the x402 protocol (USDC); unpaid requests return HTTP 402 with payment terms in the PAYMENT-REQUIRED header. Terms of service: GET /terms (free).
Output
A structured study dossier containing trial metadata from ClinicalTrials.gov, including protocol details, eligibility criteria (inclusion/exclusion), current status, sponsor information, trial phase, endpoints, and any recorded change-deltas showing what fields have been updated since previous versions.
Example use cases
Checking trial eligibility for a patient
“Pull up the full details for clinical trial NCT03769506 — I need to see the inclusion and exclusion criteria to check if my patient might qualify.”
Monitoring trial status changes
“Get the latest dossier for NCT04368728 and tell me if anything has changed since it was last updated — especially recruitment status or protocol amendments.”
Pharmaceutical competitive intelligence
“Retrieve the complete study record for NCT05172492 so I can review the trial design, sponsor, phase, and endpoints for my competitive landscape report.”
Technical details
Endpoint
GEThttps://x402-trialscope.onrender.com/study/%7BnctId%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need detailed, structured information about a specific known clinical trial identified by its NCT ID. Prefer this over general search when you already have the trial identifier and need the full dossier including eligibility, protocol, status, and change history. It is particularly valuable when you need to monitor changes to a specific trial record over time. Not suitable for discovery of trials by condition or keyword — use a search endpoint for that.
Side effects
- HTTP 402 returned if USDC payment via x402 protocol is not included or is insufficient
- Invalid or non-existent NCT ID returns an error or empty result
- ClinicalTrials.gov upstream unavailability may cause fetch failures
- Malformed NCT ID format may cause a bad request error
- Trial record may be incomplete if ClinicalTrials.gov has sparse data for that study
