How this service works
URL intelligence for AI agents
Output
Returns a JSON object containing the full redirect chain as an ordered array of intermediate URLs, the final resolved URL, and the total number of redirects followed. Each entry in the chain represents one hop in the redirect sequence.
Example use cases
Phishing link investigation
“I got a suspicious link in my email — can you follow all the redirects for https://tinyurl.com/susp1c10us and show me every hop it takes before the final destination so I can see if it's hiding something malicious?”
Short URL expansion for brand safety
“Before we approve this influencer post, can you unshorten this link https://ow.ly/brand123 and trace every redirect so we know exactly where our audience will end up?”
SEO redirect audit
“Can you check how many redirect hops this URL goes through — https://oldsite.com/legacy-page — and show me the full chain so I can see if there are unnecessary redirects hurting our SEO?”

Choose this endpoint when you need to resolve the complete redirect chain of a URL rather than just the final destination — particularly useful for security analysis, phishing detection, link auditing, or SEO diagnostics. It is a paid API ($0.01 USDC per call via x402) suited for agent workflows that need programmatic redirect tracing without relying on browser-based tools.
