RPKI Route Origin Validation for a (BGP origin AS, prefix) pair — answers whether an AS is legitimately authorized to originate a prefix. Pass asn (e.g. AS15169) and prefix (CIDR, e.g. 8.8.8.0/24). Returns status (valid = a ROA authorizes it; invalid = a ROA exists but does NOT authorize this origin — a possible hijack/route-leak that RPKI-enforcing networks will drop; unknown = no covering ROA), a hijackSignal boolean, the validating ROAs (origin, prefix, maxLength), and a plain-English description. Live RIR/RPKI data via RIPEstat (keyless) — un-derivable by an LLM. The core BGP-security check; complements net.asn.
