We’re happy to announce Clearbit’s free Logo API.

While services like Gravatar make it straightforward to pull in a user’s default avatar, we haven’t found anything that caters well to company logos. And yet there’s a lot of clear use-cases ranging from setting an organization’s default image on signup to pulling in logos next to job listings.

API

The API is incredibly simple, taking a company’s domain and returning an image.

GET https://logo.clearbit.com/:domain

Behind the scenes we’re using Clearbit’s Company API, pulling images from lots of different sources such as Twitter, Facebook, Wikipedia, or the company’s own site’s meta links. We then resize and standardize the images, serving them up from a CDN.

Example

Here’s the API in action - an img tag containing the domain baremetrics.com

<img src="https://logo.clearbit.com/baremetrics.com">

Produces Baremetric’s logo:

Configuration

You can also pass us the following optional query parameters.

Parameter	Description
size	integer Size of the image returned
format	string Format of the default - either png or jpg
greyscale	boolean Enables greyscaling

To specify a default image (for when we don’t have logo handy) you can use the image’s onerror event–we’ve put together an example here.

You can find more information in our documentation. If you have any suggestions for improvements or find an odd-looking logo please let us know.
