The checker is intentionally manual.
Amazon listings and labels vary, so this tool asks for the numbers you can verify. It gives a clear 180cal pass/fail result and then shows catalog examples for comparison.
180cal supports discovery and planning. Amazon controls the live seller, price, delivery promise, checkout, returns, and fulfillment.
