How this service works
Is a US point inside a mapped wetland? National Wetlands Inventory type and size, as a permitting heads-up.
Output
Returns a verdict (wetland present or not), the NWI wetland type label and classification code, size in acres, number of overlapping NWI features, the data source URL, a timestamp of data currency, a plain-language summary, and a legal disclaimer about permitting implications. May include a 'degraded' flag if upstream data quality is reduced.
Example use cases
Pre-permit wetlands screen for development site
“Before I submit my construction permit application, can you check if the site at latitude 39.7684, longitude -86.1581 is inside any mapped wetland and tell me the wetland type and size?”
Land acquisition environmental due diligence
“I'm considering buying land at 30.3322° N, 81.6557° W — can you check whether it falls within a National Wetlands Inventory wetland and flag any permitting concerns I should know about?”
Agricultural field wetland compliance check
“We're planning to drain a low-lying field at latitude 41.8827, longitude -87.6233 — can you look up if there's a mapped wetland there and how many acres it covers so we know if we need federal permits?”
Technical details
Endpoint
GEThttps://land-survey.x402tookit.com/wetlands-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, authoritative wetlands screen for a specific US point before site development, permitting, land acquisition, or environmental due diligence. It is the right choice when you need NWI-sourced wetland type and acreage rather than a broad flood or regulatory risk overview. Prefer it over the combined first-look screen endpoint when you specifically need only wetlands data without elevation or flood zone information.
Side effects
- Coordinate outside the US — NWI only covers US territory, may return an error or null result
- Point in an area with incomplete NWI mapping — returns null wetland data with a 'notChecked' indicator
- Invalid or out-of-range lat/lon values — request rejected with validation error
- NWI upstream service temporarily unavailable — degraded flag set to true or timeout error
- Coordinate in open water or offshore — no wetland polygon match returned
