Walter AI Launches Unified API Platform for Authenticity and Humanization of Content

Walter AI has launched its unified API platform, designed to detect, humanize, and verify AI-generated content at scale. The platform is built on the company’s existing authenticity engine, which has been trusted by over 2.1 million writers and more than 12,000 educators worldwide.

The API platform brings together Walter’s tools for detecting AI text, images, and voice, as well as humanizing and verifying content. Developers can use a single key, one credit balance, and consistent request and response formats across every endpoint to integrate the platform into their products or workflows.

AI text detection, humanization, and image detection are currently available through the API platform, with voice detection, plagiarism checking, and grammar checking set to be added in the near future. Teams can start by integrating the endpoints they need and add others later without requiring new integration work.

The launch of the API platform marks a significant step forward for Walter AI’s mission to provide authenticity and humanization tools for businesses and individuals alike. As Kevin Moore, Founder of Walter AI, notes: ‘Every piece of content now carries a question: did a person really write this, and can they prove it.’ The company aims to address this challenge with its API platform.

The platform is designed for production workloads and includes features such as scoped API keys, synchronous and asynchronous processing, webhook callbacks, and polling. Usage draws from a single credit balance, with rate limits and job concurrency that scale by plan. This ensures that developers can integrate the platform into their workflows without worrying about scalability or performance issues.

Walter AI has also completed a SOC 2 Type I examination for the Security trust services criterion, conducted by independent auditor Advantage Partners. The resulting report shows an unqualified opinion with no exceptions noted, demonstrating the company’s commitment to security and compliance. Walter’s privacy practices are aligned to GDPR and CCPA, and the platform includes audit logging and scoped access controls.

The API platform is available today for developers to create accounts, generate keys, and make their first calls free of charge without requiring a credit card. Usage is credit-based, starting with a free tier and scaling through high-volume and custom enterprise plans. Documentation and code samples are available at docs.walterwrites.ai.

Walter AI’s Authenticity Platform supports more than 80 languages and is available on the web, iOS, Android, as an MCP server for use inside Claude and ChatGPT, and now through its API platform. The company aims to provide a comprehensive solution for businesses and individuals looking to detect and humanize AI-generated content.

The launch of the API platform marks a significant milestone in Walter AI’s mission to provide authenticity and humanization tools for businesses and individuals alike. With its unified API platform, developers can now integrate the company’s existing engine into their products or workflows with ease.
