Distance Calculator

Calculate distance between locations

OperationalCredits 2 per callp50 931msGeographyStar

Overview

Distance Calculator works by calculating the distance between two locations based on their latitude and longitude coordinates. It uses advanced algorithms to calculate the distance accurately and returns the distance in miles and kilometers.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/distancecalculator
curl "https://api.apiverve.com/v1/distancecalculator?lat1=36.7783&lon1=-119.4179&lat2=34.0522&lon2=-118.2437" \
  -H "x-api-key: your_api_key_here"

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

ParameterTypeDescription
lat1RequirednumberThe latitude of the first location
range -90–90
lon1RequirednumberThe longitude of the first location
range -180–180
lat2RequirednumberThe latitude of the second location
range -90–90
lon2RequirednumberThe longitude of the second location
range -180–180

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Sample response
{
  "status": "ok",
  "error": null,
  "data": {
    "distanceMiles": 199.6804337234997,
    "distanceKm": 321.2535462758628,
    "location1": {
      "latitude": "36.728450",
      "longitude": "-119.53571",
      "city": "Sanger",
      "state": "California"
    },
    "location2": {
      "latitude": "34.044662",
      "longitude": "-118.24255",
      "city": "Los Angeles",
      "state": "California"
    },
    "bearing": 198,
    "direction": "South",
    "estimatedDriveTime": "5h 11m"
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

StatusMeaningWhat to do
400Input was rejectedRead error; it names the parameter.
401Key missing or invalidCheck the header name and the key value.
403Key valid, but not permittedA key restriction or IP allow-list; see key scoping.
429Rate limited, or out of creditsRead error to tell them apart; see rate limits.

Use cases

Delivery Radius Verification
Local couriers check mile distances between warehouse coordinates and customer dropoff points to confirm addresses fall within active delivery zones.
Road Trip Itinerary Planning
When travelers add stops to a route, travel apps calculate kilometer distances between waypoints to tally total travel distance.
Real Estate Search Filtering
Property portals measure distances from listed homes to city center coordinates so apartment hunters can filter rentals by commute proximity.
Fleet Dispatch Optimization
Dispatchers compute coordinate distances between open service tickets and available technicians to assign the nearest field worker to incoming jobs.
