How this service works
ClinicalTrials.gov intelligence — search 400K+ trials by condition, intervention, sponsor, or phase. Full trial details, eligibility, outcomes, and aggregate stats. Pay-per-request via x402 on Base mainnet.
Output
A list of clinical trials matching the search criteria, including trial titles, NCT identifiers, current status, phase, sponsor, and intervention details sourced from ClinicalTrials.gov.
Example use cases
Example prompt
“Search ClinicalTrials.gov for currently recruiting Phase 3 trials studying pembrolizumab for non-small cell lung cancer — I want to see the list of matching trials with their NCT IDs and sponsors.”
Technical details
Endpoint
GEThttps://clinical.memoryapi.org/x402/clinical/trialsWhen to prefer
Use this endpoint when you need to search across the ClinicalTrials.gov database using multiple filters (condition, intervention, sponsor, status, phase) and want a list of matching trials. Prefer this over the sibling detail endpoint when you don't have a specific NCT ID yet and need to discover relevant trials. Prefer this over the aggregate statistics endpoint when you need individual trial records rather than summary counts.
Side effects
- No trials found matching the given condition or intervention — returns empty result set
- Invalid phase or status filter value — returns 400 error
- Payment not included or insufficient — returns 402 Payment Required
- ClinicalTrials.gov upstream unavailable — returns 503 or timeout
- Overly broad query returns too many results — may be paginated or truncated
