Clearbit belongs to "Customer Information API" category of the tech stack, while Slate can be primarily classified under "Documentation as a Service & Tools".

Some of the features offered by Clearbit are:

• Social lookup
• Company lookup
• Watchlist lookup

On the other hand, Slate provides the following key features:

• Clean, intuitive design — with Slate, the description of your API is on the left side of your documentation, and all the code examples are on the right side. Inspired by Stripe's and Paypal's API docs. Slate is responsive, so it looks great on tablets, phones, and even print.
• Everything on a single page — gone are the days where your users had to search through a million pages to find what they wanted. Slate puts the entire documentation on a single page. We haven't sacrificed linkability, though. As you scroll, your browser's hash will update to the nearest header, so linking to a particular point in the documentation is still natural and easy.
• Slate is just Markdown — when you write docs with Slate, you're just writing Markdown, which makes it simple to edit and understand. Everything is written in Markdown — even the code samples are just Markdown code blocks!

"Good usability" is the primary reason why developers consider Clearbit over the competitors, whereas "Easy setup" was stated as the key factor in picking Slate.
