Adzuna API vs Coresignal for AI agents

Adzuna API is a REST API from the Adzuna job search engine for searching its job ads plus salary and labour-market data. Coresignal is a B2B jobs data API and dataset of deduplicated job postings merged from many sources into one format.

The short answer

  • Adzuna API: Building a job board or labour-market tool with an aggregated, multi-country job feed plus salary data.
  • Coresignal: Large-scale, historical job-postings data for analytics, research and data products.
