How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns a geographic polygon or GeoJSON geometry representing the boundary of the area reachable from the input location within the specified time or distance threshold, along with metadata about the isoline such as mode of transport and contour value.
Example use cases
Delivery zone coverage planning
“Generate an isoline showing all areas reachable within 30 minutes by car from our warehouse at 400 Industrial Blvd, Columbus OH — I need the polygon so I can figure out our same-day delivery coverage zone.”
Walkable neighborhood analysis
“Show me the isochrone for a 15-minute walk from Times Square in New York City — I want the boundary polygon to understand what's within walking distance for pedestrians.”
Retail site catchment area
“Calculate the reachable area within 10 km of our new store at 55 Queen Street, Toronto — give me the isodistance contour so I can see the catchment area for marketing planning.”
Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/geo/isolineWhen to prefer
Use this endpoint when you need to compute reachable-area contours (isolines, isochrones, isodistance rings) programmatically without managing your own routing infrastructure. It's ideal for logistics coverage analysis, real estate catchment mapping, or any scenario where you need a geographic polygon representing travel-time or distance boundaries around a point, payable per-call with no API key setup.
Side effects
- Invalid or unrecognizable location input returns an error or empty result
- Unsupported transportation mode may return a generic error
- Extremely large isoline requests (very long distances/times) may time out or return coarse polygons
- Ambiguous query string without explicit coordinates may produce incorrect origin point
- Network connectivity issues with underlying routing engine return 5xx errors
