Use the OpenAPI specification

Last updated: September 20, 2026

We publish an OpenAPI specification for the API. You can use it to make a client or to test requests.

The specification file

Download the specification from https://app.binlookupapi.com/openapi.json.

Generate a client

Use a tool such as OpenAPI Generator to make a client in your language.

  1. Download the openapi.json file.
  2. Run the generator with the file as the input.
  3. Set the base URL to https://api.binlookupapi.com.
  4. Set the bearer token to your API key.

Test requests

You can import the file into Postman, Insomnia, or a similar tool. Add your API key as a bearer token.
