Authentication

Every JustRouting API request requires an API key, sent as an HTTP Bearer header:

Authorization: Bearer <YOUR_API_KEY>

Creating and managing keys

Click Create API Key in the Dashboard
The key is shown in full only once — save it immediately
You can create multiple keys and Revoke a compromised key at any time

# Store it in an environment variable, never in your code repository
export JUSTROUTING_API_KEY="jr_live_..."

What authentication failures look like

Missing Authorization header:

{ "error": "missing Authorization header" }

Invalid or revoked key:

{ "error": "invalid or revoked API key" }

Both return HTTP 401. Fixes: check the header spelling (Authorization: Bearer ... — there is a space after Bearer) and make sure the key has not been revoked.

Never put your API key in public browser-side code. Anyone who obtains the key can spend your quota in your name. Browser apps should proxy requests through your own backend, or contact hello@justrouting.tech to discuss direct-from-browser options.

Example requests

curl "https://api.justrouting.tech/route/v1/driving/103.708362,1.357371;103.984748,1.352212" \
  -H "Authorization: Bearer $JUSTROUTING_API_KEY"

import justrouting

client = justrouting.Client("YOUR_API_KEY")  # sent automatically on every request

const client = new Client(process.env.JUSTROUTING_API_KEY);

client := justrouting.NewClient("YOUR_API_KEY")
