How This Compares to Other H-1B Data Sources

Sites like h1bdata.info, myvisajobs.com, and levels.fyi provide H-1B salary data through browser-only interfaces. You can look up individual records, but you can't integrate the data into your applications. The H-1B Salary Data API is a programmable REST API designed for developers and data teams. Integrate H-1B salary data directly into your compensation tools, recruiting dashboards, immigration case research, or AI agents without scraping.
