Introducing APIs
Welcome to the index page of our API documentation. Coresignal offers three main data categories:
- Company data – comprehensive global company profiles for sales tech, industry research, investment, or lead enrichment
- Employee data – up-to-date and full profiles for recruitment, HR tech, investment, and trend research.
- Job posting data – freshly collected jobs for competitive intelligence and market research.
Each of these categories contains data that is processed differently:
- Multi-source data – cleaned and enriched data that combines information from multiple sources.
- Clean data – parsed, structured, and normalized data with removed duplicates and standardized formats.
- Base data – raw data that we structured and normalized to ensure ease of use.
Below is a quick overview of all our top data categories.
