The BIN Lookup API provides endpoints for retrieving information, such as cost estimates, and 3D Secure supported version based on a given BIN.


You need an API credential to authenticate to the API.

If using an API key, add an X-API-Key header with the API key as the value, for example:

-H "Content-Type: application/json" \

Alternatively, you can use the username and password to connect to the API using basic authentication, for example:

-H "Content-Type: application/json" \


The BinLookup API supports versioning using a version suffix in the endpoint URL. This suffix has the following format: "vXX", where XX is the version number.

For example:
```## Going live

To authneticate to the live endpoints, you need an [API credential]( from your live Customer Area.

The live endpoint URLs contain a prefix which is unique to your company account:


Get your `{PREFIX}` from your live Customer Area under **Developers** > **API URLs** > **Prefix**.
