## What is Coresignal?

-   Company data
-   Employee data

Up to this date, all of Coresignal's data comes from LinkedIn. Even though t Coresignal's interface is API only and there is no way to explore the data visually. Coresignal has a free plan, but in small plans the costs per credit are very high, up to $0.2 per job. They are sales-led and their pricing is heavily weighted towards customers buying expensive plans, needed to support their sales team. To fetch jobs with Coresignal, you need to use 2 API endpoints: `search` to get the [job data](/en/docs/data/job) and `collect` to get the job data.
