Extend Launches 'Verify' API to Combat AI-Generated Document Fraud at Money20/20

Extend has launched Extend Verify at Money20/20 USA, a document fraud detection API designed to help developers and AI agents validate document integrity. For fintech professionals, this addresses the growing risk of AI-generated forgeries in lending, insurance, and payments, where imperceptible alterations to bank statements or invoices can lead to significant financial losses.

What was announced

Extend Verify is a specialized API that assesses the integrity of documents before they are used to inform business decisions. The tool is designed to be integrated into automated pipelines, allowing AI agents to flag suspicious inputs autonomously. It targets several high-risk areas, including bank statements used for lending, invoices for payment authorization, and receipts for insurance claims.

The system utilizes a combination of specialized models, forensic checks, and agentic analysis to identify four specific types of fraud. These include entirely AI-generated documents, localized AI-tampering where specific fields or characters are edited, conventional digital alterations made with PDF software, and changes made to documents after they have been digitally signed. When a document is processed, Verify returns risk assessments, scores, and traceable evidence, providing a clear explanation for why a file might be considered suspicious.

In terms of performance, Extend reported that Verify detected 96.3% of fraudulent documents in a benchmark evaluation, maintaining a 4.0% false-positive rate. This balance is intended to mitigate the burden on human review teams by ensuring that legitimate documents are not frequently flagged. The API is available immediately and can be used as a standalone product or as part of Extend’s existing document processing platform, which handles parsing and data extraction.

The companies involved

Extend is a fintech infrastructure provider that focuses on document processing and AI-driven automation. The company, which operates via paywithextend.com, provides an all-in-one platform that allows businesses to parse, split, and extract data from various financial documents. By positioning itself at the intersection of document integrity and data extraction, Extend serves financial institutions and developers who are building autonomous workflows.

Led by CEO Kushal Byatnal, the firm has established a presence in the market by bridging the gap between raw data and actionable business intelligence. Its tools are frequently used to streamline back-office operations, particularly for small-to-medium business (SMB) clients and their banking partners. As the industry shifts toward agentic AI—where software agents make decisions with minimal human intervention—Extend has focused on providing the underlying trust layer necessary for these agents to operate securely. The company’s move into fraud detection via API indicates a strategic focus on the security requirements of the modern automated financial ecosystem.

What FF News has reported before

FF News has previously covered Extend’s efforts to bring AI-driven automation to the banking sector. In October 2026, the publication reported that Extend Launches AI Receipt Agent to Automate SMB Expense Management for Bank Partners. That initiative was designed to help bank partners offer their small business customers a way to automate the tedious process of expense management using specialized AI agents. The introduction of Extend Verify builds on this foundation by adding a security layer to the data extraction capabilities previously reported, ensuring that the documents being processed by such agents are authentic.

What this means

The launch of Extend Verify highlights a critical hurdle in the adoption of autonomous AI: the trust gap. As financial institutions move away from human-in-the-loop systems, they become more vulnerable to sophisticated, AI-generated forgeries that are invisible to the human eye. This announcement places significant pressure on traditional OCR and document processing providers that lack native forensic capabilities. The industry is reaching a point where the ability to verify the authenticity of a digital document is just as valuable as the ability to read its contents. For the sector at large, the success of these verification tools will likely dictate the pace at which regulators allow fully autonomous lending and claims processing to scale.
