ip_triage — Answer "is this IP safe?" for a single address.
ip_triage_bulk — Triage up to 100 addresses in one call and return a table ranked worst-first.
ip_context — Deep detail for one address when ip_triage is not enough: reverse DNS and what the PTR pattern implies, inferred point-of-presence from carrier rDNS, the full covering-prefix routing view, the announcing AS with its registry record, and the network abuse contact.
asn_search — Resolve a free-form query to AS numbers.
asn_lookup — Who operates an AS number: organisation, registry record, announced prefix counts, the curated network kind (hosting / residential / mobile / business / education / transit), and a curated description of what the network actually does where one exists.
asn_reputation — Answer "is this whole network bad?" — Spamhaus ASN-DROP membership, the count of FBI IC3 indicators attributed to the AS, the curated network kind, and how big the network is.
blocking_advice — Answer "I want to block this — at what scope, and what will it break?" Accepts an IP, a CIDR, or an AS number.
threat_intel — Look up FBI IC3 advisory indicators for an IP or an ASN, with the advisory titles, publication dates, and source URLs.
