How this service works
Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.
Output
Returns a per-study array with the NCT ID, each date field comparison (status: MATCH, MISMATCH, or UNKNOWN), the expected date interval (earliest/latest/precision), the reported date from ClinicalTrials.gov, full source provenance including license and attribution, freshness metadata indicating retrieval time, and any applicable limitations.
Example use cases
Audit clinical trial milestone dates
“I have three NCT IDs from our portfolio — NCT00110383, NCT04512345, and NCT03987654 — and I need to verify whether their startDate and completionDate match what ClinicalTrials.gov actually shows. Can you check all three and tell me which ones have discrepancies?”
Regulatory submission date verification
“Before we finalize our regulatory filing, can you confirm that NCT00110383's lastUpdatePostDate is 2025-03 and that the completionDate is 2026-09 per the official ClinicalTrials.gov record?”
Clinical trial portfolio compliance check
“Our database shows NCT04123456 should have started in 2023-06 and NCT05678901 should have completed in 2024-12 — can you verify both of those against ClinicalTrials.gov and flag any that don't match?”
Technical details
Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/clinical-study-date-contractWhen to prefer
Choose this endpoint when you need authoritative, evidence-backed comparison of expected clinical trial milestone dates against the live ClinicalTrials.gov registry — especially for compliance audits, regulatory filings, or data reconciliation workflows where source provenance and freshness metadata matter. Prefer this over manual ClinicalTrials.gov lookups when you need structured JSON output with explicit match/mismatch status and bounded factual records rather than free-text scraping.
Side effects
- Invalid NCT ID format (not matching ^NCT\d{8}$) causes validation error
- Unknown or unrecognized NCT ID returns UNKNOWN status for all date comparisons
- ClinicalTrials.gov upstream unavailability may result in null reported values
- More than 3 studies or more than 3 date fields per study exceeds schema limits
- Unsupported date field enum values cause request rejection
- Payment not received causes 402 response before processing
