Atomara checks whether a PDF was edited after the issuer wrote it. Lenders and platforms send a bank statement, payslip, invoice, or similar file over a REST API and get back JSON with a verdict, a 0 to 100 authenticity score, and every forensic signal the engine found, including the page and area where it appears. The engine reads the file itself: generator and editor fingerprints, incremental save history, font and layout consistency, digital signatures, and whether statement figures add up line by line. It is issuer-agnostic by design, so there is no bank-template list to wait for, and when the method cannot tell it returns inconclusive rather than guessing. The same result is available in the Atomara dashboard for the person reviewing a flagged application. Digital PDFs carry the full check; scans and photos of paper documents are accepted but do not receive a structural authenticity score.
