MAC Address Lookup

Find the vendor name of a device by entering an OUI or a MAC address

API Documentation V2

The MAC Lookup Rest API is available for free and provides a powerful tool for retrieving detailed information about any MAC address or OUI (Organizationally Unique Identifier).

With this API, you can seamlessly integrate MAC address and OUI lookup functionality into your applications, services, or systems.

Key features of our MAC Lookup Rest API include:

High Volume Support: Designed to handle a high volume of requests efficiently, our API is suitable for projects of any scale.
Low Latency: We prioritize low latency to ensure that you get fast responses to your queries, allowing your applications to perform at their best.
Rich Data: Our database contains extensive information about MAC addresses and OUIs, including vendor details, address types, and more.
User-Friendly: The API is easy to use and integrate into your applications, with comprehensive documentation and support available.

This documentation is intended for developers who want to query MACLookup API.

The same contract is published as an OpenAPI document, for tools and agents that read a specification rather than a page.
