How this service works
Audit a supplied evidence inventory for freshness, source type, sample disclosure, methods and reuse permission. Returns per-source flags by position; no raw reports, population claims or legal clearance.
Output
Returns an array of per-source quality flags keyed by position in the input list, indicating issues with freshness (relative to maximumAgeDays), whether the source is primary or secondary, adequacy of sample size disclosure, methods availability, and reuse permission status. Does not return raw reports, population-level claims, or legal clearance.
Example use cases
Pre-publication evidence freshness check
“Before we finalize the report, can you audit my 5 evidence sources? Source 1: 60 days old, primary, sample 2000, methods available, reuse yes. Source 2: 200 days old, secondary, sample 150, no methods, reuse unknown. Source 3: 730 days old, primary, sample 500, methods available, reuse yes. Source 4: 45 days old, secondary, sample 80, no methods, reuse no. Source 5: 300 days old, primary, sample 1000, methods available, reuse yes. Flag anything exceeding 365 days as stale.”
Policy brief source permission audit
“I need to check reuse permissions and methods availability for my policy brief sources — source 1 is 90 days old, primary, sample 5000, methods available, reuse yes; source 2 is 120 days old, secondary, sample 300, no methods, reuse unknown; source 3 is 30 days old, primary, sample 750, methods available, reuse no. Max age threshold is 180 days.”
Research tool quality gate before synthesis
“Can you flag any quality issues in my 4 research sources before I synthesize them? Source 1: 15 days old, primary, 10000 samples, methods available, reuse yes. Source 2: 500 days old, secondary, 200 samples, no methods, reuse unknown. Source 3: 22 days old, primary, 4500 samples, methods available, reuse yes. Source 4: 85 days old, secondary, 60 samples, no methods, reuse no. Treat anything over 270 days old as too old.”

Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/research/evidence-quality?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, per-source quality audit of an evidence inventory before using it in research, policy, or decision-making workflows — particularly when freshness thresholds, methods transparency, and reuse rights are all relevant dimensions. Prefer it over manual review when auditing multiple sources at once and needing machine-readable flags per source position.
Side effects
- Missing required source fields (ageDays, primary, sampleSize, methodsAvailable, permissionToReuse) returns validation error
- Sources array exceeding 20 items rejected
- ageDays or sampleSize outside allowed range returns schema error
- maximumAgeDays outside 1–3650 range rejected
- Empty sources array rejected
- Payment not received or insufficient USDC results in 402 response
