Coresignal

Coresignal provides regularly refreshed public web data through APIs, datasets, and self-service search tools. Its main data products cover companies, employees, job postings, and company or employee posts, with records designed for enrichment, research, recruiting, investment analysis, and AI applications. The documentation describes 4.5 billion-plus records with timestamps tied to collection cycles. Teams can choose a workflow that fits their stack: query company, employee, and jobs APIs; work with downloadable datasets in JSON or CSV; or search and enrich records through no-code dashboard tools. APIs include base, clean, and multi-source variants, Elasticsearch DSL, bulk collection, search previews, contact enrichment, and webhooks. The Agentic Search API accepts natural-language prompts through Fast and Reasoning endpoints, while the MCP server connects Coresignal data to compatible AI tools and agent workflows. Coresignal is aimed at sales and marketing teams enriching leads, recruiters and HR technology companies sourcing talent, investors evaluating companies, researchers studying markets, and developers building AI-ready data products. Pricing varies by access type and usage: database API plans are credit-based, while full datasets are priced by agreement factors such as contract duration, processing level, and record count.
