How this service works
Check up to eight numeric grant claims for source traceability, population/geography/period consistency and arithmetic. Returns corrected values where supported plus specific evidence gaps; no private narratives needed.
Output
Returns per-claim validation results including arithmetic correctness (with corrected values where the math is wrong), flags for source traceability failures, and specific evidence gaps across population, geography, period, version, and unit consistency dimensions. No private narrative data is required or returned.
Example use cases
Grant report arithmetic audit
“I need to verify five numeric claims in our organization's federal grant report before submission — here are the figures: claim 1 is numerator 1200, denominator 4000, claimed value 30 percent, unit percent, source available, version matches, population matches, geography matches, period matches, units match, inputs verified; claim 2 is numerator 50, denominator 200, claimed value 25 percent, unit percent, source not available, version matches, population matches, geography matches, period matches, units match, inputs verified — can you check the math and flag any evidence gaps for all five?”
Cross-geography grant consistency check
“We're auditing a grant application where the claimed population figures span two different regions — can you trace these two claims: claim 1 is numerator 800, denominator 2000, claimed value 40 percent, unit percent, source available, version matches, population matches, geography doesn't match, period matches, units match, inputs verified; claim 2 is numerator 5000, denominator 10000, claimed value 500 per_1000, unit per_1000, source available, version matches, population matches, geography matches, period doesn't match, units match, inputs not verified — and tell me which ones have consistency problems?”
Nonprofit grant claim evidence review
“Before we submit our grant renewal, can you check whether our three key statistical claims hold up — claim 1 numerator 120, denominator 600, claimed value 200 per_1000, unit per_1000, source not available, version doesn't match, population matches, geography matches, period matches, units match, inputs verified; claim 2 numerator 75000, denominator 300000, claimed value 25 percent, unit percent, source available, version matches, population doesn't match, geography matches, period matches, units match, inputs not verified; claim 3 numerator 4500, denominator 1, claimed value 4500 usd, unit usd, source available, version matches, population matches, geography matches, period matches, units match, inputs verified — flag any correctable errors or missing evidence?”
Technical details
Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/grants/claim-trace?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to audit specific numeric claims in grant applications, reports, or proposals for arithmetic accuracy and source traceability — especially when you have structured numerator/denominator data and can supply boolean consistency flags. It is particularly valuable for grant compliance workflows, pre-submission audits, and identifying evidence gaps without exposing private narrative content. Prefer this over general fact-checking tools when the domain is specifically grant funding statistics with known source metadata.
Side effects
- Array contains more than 8 claims — request rejected
- Missing required fields (numerator, denominator, claimedValue, unit, or boolean flags) — validation error
- Numeric values exceed maximum of 1,000,000,000 — schema rejection
- Source not available and multiple consistency mismatches — evidence gap reported without correction
- Denominator of zero causing division-by-zero in percent/per_1000 calculations — may return error or null corrected value
