BIN Lookup API Quickstart

Follow these steps to send your first BIN lookup.

1. Create an account and an organisation

You need a Google account or a Microsoft account. BINLookupAPI does not use a password.

Open https://app.binlookupapi.com/sign-in.
Select Google or Microsoft.
Complete the sign-in steps of that provider.

On the first sign-in, the dashboard shows the Create Organisation form.

Enter the name of your organisation.
Select Create Organisation.

The new organisation starts on the free tier. The free tier includes 10 real lookups each day. You do not need a payment card.

If you have an invitation, accept it. You then join that organisation. You do not create a new one. See Accept an invitation.

2. Create an API key

Open API Keys.
Enter a name for the key. Use 1 to 100 characters. Example: Development.
Select Create Key.
Copy the key and store it in a safe place.

CAUTION: The dashboard shows the full key one time only. You cannot see the full key again.

The key starts with blapi_live_. The dashboard then shows a curl command that contains the new key.

Only an owner or a developer can create keys. See API keys.

3. Send the first request

The free tier returns real production data. The limit is 10 requests each day.

curl -X POST "https://api.binlookupapi.com/v1/bin" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"number": 42467101}'

Replace YOUR_API_KEY with your key. A success response looks like this:

{
  "mode": "live",
  "data": {
    "bin": "42467101",
    "scheme": "visa",
    "funding": "debit",
    "brand": "VISA",
    "category": "CLASSIC",
    "country": { "code": "PL", "name": "POLAND" },
    "issuer": { "name": "ING BANK SLASKI SA", "website": null, "phone": null },
    "currency": "PLN",
    "prepaid": false,
    "commercial": false
  }
}

Field definitions are in the API reference.

4. Confirm the request on the Usage page

Open Usage.
Find the request in the request history.

The history columns are time, BIN, API key, HTTP status, and response time. See the dashboard page.
