Hey Alex,

This is pretty sweet. Nice job! Is there a post where you talk about the tech behind this API? I've been working on a simple API that finds domain names from company names that I use on projects where I use business intelligence APIs like Clearbit and FullContact.

Behind the scenes we're using Clearbit's Company API which does a lot of sleuthing: scanning the page for social accounts, meta tags etc. Then we try and return the best logo we can find.

Fetch the domain at /, look for favicon/apple-touch-icon/OpenGraph image, fetch the image, store and serve.

Looks like it has twitter as a secondary source, eg.

https://logo.clearbit.com/spacex.com https://twitter.com/spacex

Maybe other fallbacks, too?

Also seems like some fairly primitive analysis would identify this as a suspect item, at least enough to be shunted off to some sort of triage. Logos, by and large, will have distinctly different data than images.

That, and it also doesn't match their favicon.

Good catch, that's pretty hard to deny

When I saw the tagline "Business Intelligence APIs" at the top of the posted link, I totally thought Clearbit's line of business was something completely different-- more along the lines of data warehousing, analytics and reporting.

I wish Clearbit had a "very early stage" plan - say 1000 requests a month, which I could use with proof of concept or little side project systems. 50 free requests isn't much: by the time you've demo'd to 5 people for feedback they'd be gone.
