URL Threat Detection API
An API that investigates URLs in real time — no blacklists, no stale databases. Built for developers and security teams who need additional real-time security signals.
400 free requests on signup. No credit card required.
How it works
Not a lookup. An actual investigation.
Live Browser Rendering
We spin up a headless browser and fully load the target URL — executing JavaScript, following redirects, and capturing the real rendered page.
Multi-Modal AI Analysis
Our AI reads the page the way a human analyst would — examining the visible content, DOM structure, and visual layout simultaneously to determine intent.
Clean JSON Response
You get back a structured risk score, threat classification, and the evidence behind the decision — ready to act on in your application.
About this service
A developer-grade layer on top of URLert.
Built on the URLert platform
This API is the programmatic interface to the same engine powering urlert.com — a consumer threat analysis tool used to investigate suspicious links. The developer API exposes that capability directly for integration into your own products.
