## Request

- Auth: none required

FCC National Broadband Map link for agents at a US address or point: fixed-broadband providers, fiber, cable, fixed wireless, satellite, max advertised speeds, and vintage. FCC and ISP-reported availability only. National. Never a fast, slow, good, or bad verdict, and Locus does not redistribute the FCC location dataset. 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.

## Response `200`
