RDAP — Registration Data Access Protocol (domains, IPs, ASNs) via IANA bootstrap

Domain registration for AI agents via Stripe or x402 crypto with Cloudflare DNS.

Provides capabilities that let LLM agents perform a range of infrastructure management tasks.

The internet's largest queryable infrastructure graph — 7.39 billion nodes, 39 billion edges, 5.6 million threat-intelligence relationships. Pivot from any IP, domain, or ASN across DNS, BGP, WHOIS, GeoIP, and threat intel in a single Cypher query. Most threat-intel and OSINT APIs are point lookups: you ask about one indicator, you get one record. Investigations don't work that way — you start from one suspicious domain and need to trace its hosting, its sibling domains, its registrar, its email

Scan your home network and local machine for security risks, open ports, weak Wi-Fi, unknown devices. Providing with a trust score and clear explanations.

Gives AI agents a public IPv6 identity, hostname, port forwarding, web fetch, team mesh. Free tier.
