Major ATS Platforms Offer Free Public JSON APIs for Job Listings Few Know About

The four dominant applicant tracking systems — Greenhouse, Lever, Ashby, and SmartRecruiters — each expose public, keyless JSON APIs that return complete job listing data without any authentication or HTML parsing. These endpoints cover job boards for major companies including Stripe, Figma, Airbnb, Ramp, Plaid, and Visa, and can return hundreds of open roles in a single request. Each API uses different field names and structures, so developers must normalize the data into a common schema to make cross-platform comparisons practical. A known challenge is that company board tokens do not always match brand names, requiring slug variations to be tested across all four providers. Once normalized and run on a daily schedule, the data can power personal job alerts, niche job boards, or hiring trackers that flag new openings within hours of posting.
