Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns a GeoJSON polygon or multipolygon geometry representing the boundary of the reachable area (isochrone or isodistance contour) around the input origin point, encoded as geographic coordinates.
Example use cases
Example prompt
“Generate an isoline showing every area reachable within 20 minutes by car from coordinates 40.7128, -74.0060 in New York.”
Technical details
Endpoint
POSThttps://apex-api-gamma.vercel.app/api/geo/isoline?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute reachable-area contours (isochrones or isodistance rings) around a geographic point — for example, to define delivery zones, service catchment areas, or travel-time buffers. Prefer it over simple radius circles when road network or pedestrian path accuracy matters.
Side effects
- Invalid or missing origin coordinates return a 400 error
- Unsupported transport mode causes a validation error
- Very large time/distance thresholds may time out or return oversized polygons
- Coordinates outside supported map data coverage return empty or partial results
- Malformed query string causes parsing failure
