Clearbit offers solutions for developers to construct business intelligence APIs. Using the Clearbit Company API, users can lookup company information by URLs to retrieve public data on company name, amount of funding acquired, the company's market sector, and the number of employees. All calls and responses with the Clearbit REST API are done in JSON formats over a secure SSL connection. Clearbit also offers other services such as email lookup, OFAC verification, and geolocation. The API is able to take up to 600 calls per minute. Webhooks are offered for calls that require processing time. Clearbit also offers Ruby & Node.js bindings for the API.
