x402 APIPassing, checked 1 h ago
Follow a short link's redirect chain (bit.ly, t.co, youtu.be, tracking links, …) without downloading any page body: returns the final URL, the final HTTP status, and every hop with its status code and Location target. Capped at 5 redirects; every hop is SSRF-re-validated, so chains that dive into private networks are blocked. Lets agents pre-flight links before fetching or citing them.
