How this service works
URL -> safety verdict. Checks the redirect chain, detects homograph/punycode hostname tricks, and cross-references the destination host against the URLhaus threat feed. Use to vet a single URL before fetching, sharing, or acting on it. For a full domain configuration grade use /sitegrade; for ownership/registration facts use /domain-intel.
Output
A safety verdict for the submitted URL, including the full redirect chain analysis, detection of homograph or punycode hostname obfuscation techniques, and a cross-reference result against the URLhaus malicious URL threat feed indicating whether the destination host is flagged.
Example use cases
Phishing link triage in email
“Someone forwarded me a link that looks like it's from my bank: https://secure-bankofamerica.login-verify.com/auth — can you check if this URL is safe or if it's using any lookalike domain tricks before I open it?”
Pre-fetch safety gate for AI agent
“Before you scrape data from https://bit.ly/3xK9pQr, run a safety check on that URL — I want to know where it redirects and whether the final destination is flagged as malicious.”
Vetting a shared link before publishing
“I'm about to include https://freesoftware-download.net/tool.exe in our newsletter — can you verify if that URL is safe, check its redirect chain, and confirm it's not listed in any threat databases?”
Technical details
Endpoint
GEThttps://tariffmonkee.com/paid/linkcheckWhen to prefer
Choose this endpoint when you need a fast, single-URL safety verdict before fetching, sharing, or acting on a link — especially when homograph/punycode domain spoofing or redirect-chain obfuscation are concerns, and you want URLhaus threat feed cross-referencing. Use /sitegrade for a full domain security configuration grade, and /domain-intel for WHOIS/registration facts. Use the /bundle endpoint if you want all three checks at once.
Side effects
- Invalid or malformed URL returns an error
- URL is unreachable or times out during redirect chain analysis
- URLhaus feed lookup may have temporary availability issues
- Highly obfuscated URLs may partially evade redirect chain resolution
- Payment not settled causes 402 response before check is performed
