How this service works
Hold what a document says about one US address next to dated official records. Modes: listing (advertised area, year built, additions, permits vs parcel and permit records), assessment_notice (figures and the notice's own printed date vs the roll and the cited statutory appeal rule), inspection_excerpt (observations mapped to the records that publish that work, plus questions for a pro). Charge-free without cited evidence. npx @velinussage/locus-agent-skill add.
Output
A structured response citing official parcel, permit, and assessment records alongside each claim from the submitted document. Each claim is either supported by a dated official source or flagged as unsubstantiated. Modes include listing (advertised area, year built, additions, permits vs records), assessment_notice (figures and appeal deadline vs roll and statute), and inspection_excerpt (observations mapped to permit records with suggested professional follow-up questions). Unsupported claims return no charge.
Example use cases
Buyer due diligence before offer
“Before I put in an offer on 215 Oak Hill Dr, Charlotte NC, can you verify the listing's claimed square footage and 2018 addition against official parcel and permit records to see if anything doesn't add up?”
Assessment notice appeal window check
“I received an assessment notice for my property at 88 Birchwood Ave, Durham NC — can you check whether the figures and the appeal deadline it cites match the official tax roll and the statutory rule?”
Inspection report claim verification
“My home inspection report for 7 Creekside Blvd, Cary NC mentions recent HVAC and roof work — can you map those observations to official permit records and flag anything that lacks a pulled permit?”
Technical details
Endpoint
POSThttps://api.locus.report/api/locus-listing-claim-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need citation-backed verification of specific claims in a US property document (listing, assessment notice, or inspection excerpt) against official government records. Prefer this over generic property lookup APIs when you need to audit advertised figures, renovation claims, or assessment appeal deadlines rather than simply retrieve raw property data. Particularly valuable pre-offer, pre-appeal, or post-inspection when claim accuracy has financial or legal consequences.
Side effects
- Address not found in official records — returns no supporting data for that jurisdiction
- Jurisdiction not covered — parcel or permit data unavailable for the given county or municipality
- Malformed subject object — returns validation error if required address fields are missing
- No verifiable claims submitted — endpoint returns empty result with no charge
- Permit records incomplete or not digitized — some older permits may not appear in official feeds
