How to use Apollo

How it works

API Calls

Need B2B data for a company or contact from Apollo? Our REST API lets you query for whatever data you are looking to enrich your system with. Whether for people, organizations, opportunities, or more, the Apollo API is available to do almost everything the UI offers. Some additional functionalities not available in the UI are also offered through our API.


Apollo's API is charged based on consumption, and API calls are only counted when a request is made to our server. Varying plans offer different levels of API access. To view how many requests your current plan allows and how many requests you have used, you can reference the headers of a successful response from the API.

Note: Requests are not counted differently depending on number of records that may be returned or updated in a single request.
