How this service works
First-look site screen for a US coordinate: elevation, FEMA flood zone and mapped wetlands combined, with flags.
Output
Returns a JSON object with: ground elevation in feet, FEMA flood zone code and class, base flood elevation, special flood hazard area boolean, wetland presence data, a plain-language summary, a verdict string, human-readable flags array, reasons list, data-degraded indicator, source attribution URL, and a disclaimer. Includes a notChecked array listing any data layers that could not be retrieved.
Example use cases
Pre-purchase rural land due diligence
“Before I put in an offer on that parcel in Tennessee, can you screen lat 35.8456, lon -86.3920 for flood zone status, wetlands, and elevation so I know if there are any red flags?”
Construction site feasibility check
“We're scoping a build in rural Georgia — run a site screen on lat 31.9500, lon -83.3800 and tell me if it's in a FEMA special flood hazard area or has any wetland coverage that could complicate permitting.”
Solar farm candidate screening
“Screen coordinates lat 34.2100, lon -92.0150 in Arkansas for elevation, flood risk, and wetlands — I need to know if this candidate site has any environmental constraints before we move it forward.”

Endpoint
GEThttps://land-survey.x402tookit.com/site-screen?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, combined first-look screen of a US coordinate covering elevation, flood zone, and wetland presence in a single call rather than querying each layer separately. It is ideal for pre-purchase due diligence, permitting pre-checks, or triage workflows where you want a verdict and flags without orchestrating three separate API calls. Prefer the individual sibling endpoints (flood-only, elevation-only, wetland-only) when you need deeper detail on a single layer.
Side effects
- Coordinates outside the US return null or incomplete data for FEMA and elevation layers
- Degraded flag set to true when one or more data sources returned partial or stale data
- notChecked array populated when a data layer (flood, wetland, or elevation) could not be queried
- Invalid lat/lon values result in a 4xx error
- USGS or FEMA upstream service outages may cause missing elevation or flood data
