How this service works
Inspect a URL: follow its redirect chain hop by hop with SSRF guards, and flag punycode, IP hosts, brand lookalikes, shorteners, http downgrades and phishing patterns.
Output
Returns a JSON object with the canonical input URL, the final resolved URL after all redirects, the number of redirects, an ordered array of redirect hops, a numeric risk score, a risk level label (e.g. low/medium/high), an array of risk/status flags (e.g. punycode, shortener, http-downgrade, brand-lookalike, ip-host, phishing-pattern), the final HTTP status code, a note with caveats, and the data source.
Example use cases
Phishing link triage for security team
“We got a suspicious email with this link: http://paypa1-secure.com/verify — can you follow its redirect chain, score its risk, and flag any punycode, lookalike brand, or HTTP downgrade issues?”
URL shortener transparency check
“Before I share this shortened link with our users — https://t.co/abc123xyz — can you trace where it actually goes hop by hop and tell me the final destination and risk level?”
Automated link safety gate in agent workflow
“I need you to check https://free-invoice-download.xyz before we let it through our pipeline — show me the full redirect chain, risk score, and any phishing or IP-host flags it raises.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/url/risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need hop-by-hop redirect tracing combined with security signal detection (punycode, brand lookalikes, IP hosts, shorteners, HTTP downgrades, phishing patterns) in a single call with SSRF protection built in. Prefer it over generic HTTP-follow libraries when the agent needs a structured risk score and named flags rather than raw response data.
Side effects
- URL is unreachable or times out — returns error or null final_status
- SSRF guard blocks private/internal IP ranges — request rejected with appropriate flag
- Malformed or non-HTTP/HTTPS URL provided — validation error
- Redirect loop detected — may return partial hop chain
- Rate limiting or payment failure for $0.01 USDC per call
