How this service works
Metro area context for a US address or lat/lon: metro or micropolitan area, urban area, county and urban or rural setting.
Output
Returns a structured object including: the metro or micropolitan statistical area (name and code), urban area (name and code), combined statistical area (name and code), county name and GEOID, state, urban/rural setting classification, a human-readable summary and verdict, data source and URL, data freshness timestamp, and any degraded-mode flags or disclaimers.
Example use cases
Real estate market area classification
“I'm evaluating a property at 1500 Market St, Philadelphia, PA — can you tell me what metro area it falls in, the county, and whether it's classified as urban?”
Rural vs urban eligibility check
“We need to determine if the location at latitude 38.9072 and longitude -77.0369 qualifies as rural or if it's in a metro area — can you look that up for our grant application?”
Sales territory metro contextualization
“Our sales team covers 450 Main St, Bozeman, MT — is that in a metro or micropolitan area, and what's the broader combined statistical area if there is one?”

Endpoint
GEThttps://geo-us.x402tookit.com/metro-area?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need Census-defined metro/micropolitan area classification, urban area codes, or urban/rural setting for a US address or coordinate — especially for eligibility checks, market segmentation, demographic enrichment, or regulatory compliance that relies on official Census statistical area definitions. Prefer this over generic geocoding endpoints when the goal is metropolitan context rather than just lat/lon coordinates.
Side effects
- Address cannot be geocoded or is outside the US — returns null fields or an error
- Lat/lon falls outside US Census-covered territory — returns empty metro/urban fields
- Neither address nor lat/lon provided — request fails validation
- Ambiguous address matched to wrong location — results may be incorrect without verification
- Degraded mode may return partial results if upstream Census data is unavailable
