## What ExChek API Does

ExChek provides an API for U.S. export control classification (ECCN, BIS, ITAR). You describe your product; the API determines jurisdiction (EAR vs ITAR) and runs an Order of Review using live eCFR data (15 CFR Part 774 and 22 CFR Part 121). A human reviews and refines each step until the classification is approved, then receives an audit-ready report.
