AI-assisted URL threat detection API for developers
Every scan returns a numeric score plus explanatory reasons, so you can act on a link with confidence rather than trusting an opaque verdict.
Short links and redirect chains are unwrapped and followed, revealing hidden final destinations before they reach your users.
Links are classified across phishing, malware, scam, adult, dating, gambling, crypto and spam, supporting nuanced content policies.
Send batches of URLs in a single request and receive per-link risk scores, which suits high-volume pipelines and link shorteners.
Detect, humanize and verify AI content in one place
Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
