Google Safe Browsing

Web & SEO Tools

Operated by Sourcelane✓ verified

A URL screening connector that checks lists of URLs against Google's Safe Browsing threat database to produce per-URL safety verdicts and matching threat details. It performs high-throughput, bulk URL lookups via the Safe Browsing Lookup API, automatically chunks inputs into API-sized batches, preserves original input order while de-duplicating, and is error-tolerant at the batch level. For each URL it returns a boolean safety verdict plus a list of matching threats and associated threat metadata such as threat type (MALWARE, SOCIAL_ENGINEERING, UNWANTED_SOFTWARE, POTENTIALLY_HARMFUL_APPLICATION), platform type, and Google’s recommended cache duration. Designed for large-scale screening, triage, and auditing workflows and includes a provably-flagged test URL for end-to-end verification.
