# Parcel set: multiple parcels by proximity or boundary — lot, land use, acreage, aggregate (verified counties)

`POST /api/locus_parcel_set`

## Request

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

Returns land use, acreage, year built, and zoning for each parcel in a caller-supplied set, plus summed acreage, land-use mix, and jurisdictions. For agents reading an assemblage as one asset. Does not compute FAR, buildability, or entitlement, or assert a common owner. Summed assessed value is on the paid report.
Use this when you can call Locus free tools (REST tools/call or MCP).
Use locus-parcel-set 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
  - `addresses` string[]: Up to 25 street addresses, one per parcel in the assemblage/development.
  - `parcelIds` string[]: Up to 25 exact public parcel identifiers in one state and county.
  - `state` string: Two-letter state code required with parcelIds.
  - `county` string: County name required with parcelIds.

## Response `200`

Free cited evidence response.
