Distance between points

The great-circle distance between two latitude and longitude pairs, plus the bearing.

curl -X POST "$DOATHING_API/v1/core/geo-distance" \
  -H "x-api-key: $DOATHING_KEY" \
  -H "content-type: application/json" \
  -d '{"from": [51.5074, -0.1278], "to": [48.8566, 2.3522]}'

The great-circle distance between two latitude and longitude pairs, plus the bearing.

Compute great-circle distance and initial bearing between two coordinate pairs.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

Cost

1 credit per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.

Parameters

Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
