OOPSpam is a spam and fraud detection API aimed at developers and site owners who need to stop spam submissions without adding CAPTCHAs or collecting user data. Founded in 2017, the product exposes a REST API (also available on the RapidAPI marketplace) that developers can call to check form submissions, comments, and signups for spam and fraud signals, and it offers a companion Domain Reputation Watch feature to monitor domain reputation over time. Rather than requiring end users to solve a CAPTCHA, OOPSpam scores submissions server-side using context-aware detection, which the vendor states delivers 99.9% accuracy. It ships ready-made integrations for WordPress, WooCommerce, Zapier, Make.com, Gravity Forms, Ninja Forms, Contact Form 7, and Elementor Forms, letting non-developers add spam protection to common CMS and form tools. The company positions itself as privacy-first, stating it does not log request data by default and complies with GDPR.
