# Ownership-loop composite: dated changes around one place

`POST /api/locus_ownership_loop`

## Request

- Base URL: `https://api.locus.report`
- URL: `https://api.locus.report/api/locus_ownership_loop`
- Auth: none required

Returns one cited scan of development cases, capital projects, assessments, recent parcel sales, and the county tax calendar around a place, plus FEMA map revisions, declarations, or claims when inputs support them. For an owner or manager asking what changed. North Carolina addresses are geocoded. Not a value or risk verdict.
Use this when you can call Locus free tools (REST tools/call or MCP).
Use locus-ownership-loop instead when your client can only call paid x402 routes; it returns the same records. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.

## Request body

- object
  - `address` string: Optional US street address or place; NC uses AddressNC first, other areas use the national geocoder fallback when latitude/longitude are not provided.
  - `latitude` number: Optional decimal latitude; provide with longitude to skip address geocoding.
  - `longitude` number: Optional decimal longitude; provide with latitude to skip address geocoding.
  - `radiusMeters` integer: Optional search radius in meters for nearby ownership-loop lanes; default 1500, max 5000.
  - `county` string: Optional covered county name for the tax calendar, e.g. Wake.
  - `state` string: Optional two-letter state code for FEMA declarations; provide with countyFips3.
  - `countyFips3` string: Optional 3-digit county FIPS for FEMA declarations, e.g. 183 for Wake.
  - `zip` string: Optional 5-digit or ZIP+4 code for NFIP flood-claim history.
