URL status and redirect checker
url_status_checkRead-onlyIdempotent
Check whether links are alive: HTTP status, every redirect hop, final URL and a classification (ok, redirect, broken, restricted, blocked_by_site, disallowed_by_robots_txt, timeout). HEAD first, GET to confirm errors. Free for 1 URL when the free web tool is enabled; up to 10 URLs per call cost $0.003 USDC. Paid calls made without a payment return isError with the x402 v2 PaymentRequired object (amount in USDC atomic units, network, payTo, HTTP endpoint); retry with the signed PaymentPayload in params._meta["x402/payment"]. Invalid input and calls where every item fails are never charged. Fetches follow robots.txt, use the User-Agent AdamHaleTools/1.0 and refuse private or internal addresses.
