GET /api/clinical/trial-check

live

ClinicalTrials.gov lookup, deterministic. Answers "what is the status of NCT02142738", "recruiting phase-3 melanoma trials", "Pfizer trial pipeline". Single trial by NCT id (status, phase, sponsor, enrollment, dates, countries) or search by condition/sponsor with phase and status filters. Typed records straight off the official v2 API — no LLM, no key, public domain.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
