Last updated: September 20, 2026

This article shows how to go from a new account to a successful API response in five steps.

Step 1: Sign in

Sign in to the dashboard at https://app.binlookupapi.com with Google or Microsoft.

Step 2: Create an API key

  1. Go to API Keys.
  2. Enter a name for the key. For example, Development.
  3. Select Create Key.
  4. Copy the key. The dashboard shows the full key one time only.

Step 3: Send a request

The dashboard shows a curl command with your new key. Run this command in your terminal. Replace YOUR_API_KEY with your key.

curl -X POST "https://api.binlookupapi.com/v1/bin" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
