IOCs (URLs, domains, IPs, hashes) shared by the infosec community on X/Twitter. No auth, CC0.

Pre-signature x402 payment-risk oracle.

Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.

Scans text for personally identifiable information — emails, phone numbers, SSNs, credit card numbers, physical addresses, names — and returns a redacted version. Built for agents sanitizing user content, support tickets, logs, or documents before storage, sharing, or feeding into another LLM call. Pay-per-call via x402 (USDC on Base): $0.01/call, no account or API key. tools/list and /openapi.json are free for discovery.
