Api Endpoint

IP blocklist check

Use when an agent must decide whether an IP is already known for abuse: it checks one IPv4 address against nine public DNS blocklists at once — SpamCop, UCEPROTECT, PSBL, Barracuda, DroneBL and four more — and returns each list's raw code and the reason text it publishes, not a score. Every list is re-checked on each call with its RFC 5782 test entry, so a dead list comes back as unavailable instead of reading as clean. Includes the delisting URL for each hit.
