How this service works
The closest candidate coordinate to a query point, with great-circle distance and initial bearing.
Output
Returns the single closest candidate point from the provided list, along with the great-circle distance in meters and the initial bearing in degrees from the query point to that candidate. If the candidate had an ID, that is included in the response.
Example use cases
Nearest store locator for e-commerce
“I have a list of our 300 store locations and a customer at latitude 51.5074, longitude -0.1278 — which store is geographically closest to them, and how far away is it?”
Last-mile delivery depot assignment
“Given these 80 depot coordinates, which one is nearest to the delivery address at lat 48.8566, lon 2.3522? I also need the bearing so the driver knows which direction to head.”
Emergency responder proximity routing
“We have 50 available ambulances at different positions right now — which one is physically closest to the incident at latitude 37.7749, longitude -122.4194?”
Technical details
Endpoint
POSThttps://fittings.sh/v1/spatial/nearest-pointWhen to prefer
Use this endpoint when you need to identify the single nearest coordinate from a set of up to 5000 candidates to a given query point, getting both distance and bearing in one call. It is ideal for logistics, store-finder, fleet dispatch, or any proximity-matching workflow where you already have a list of candidate locations. Prefer this over computing pairwise distances yourself or using a full routing engine when straight-line (great-circle) distance is sufficient and you don't need road-network routing.
Side effects
- Empty candidates array returns an error or empty result
- Malformed coordinate objects (missing lat or lon) cause validation errors
- Exceeding the 5000-candidate limit may return a 400 error
- Invalid GeoJSON format (e.g. lat/lon swapped) produces incorrect results silently
- Network timeout if payload is very large
