WhisperGraph

WhisperGraph maps the entire internet into a single Cypher-queryable graph: every domain, IP, ASN, prefix, organization, and threat-intel listing connected as nodes and edges (46B+ total, real-time). Built for AI agents from day one — sign up programmatically with two HTTP calls, no browser, no CAPTCHA, no waiting list. Free trial for everyone; paid tiers for higher quotas. Works with Claude, Cursor, ChatGPT, VS Code, LangChain, and any MCP-compatible agent.
