Hosted, OAuth-gated endpoint for quantakrypto's post-quantum crypto tools: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and get NIST ML-KEM/ML-DSA/SLH-DSA migration guidance over authenticated HTTP — nothing to install. Sign-in required (Google/GitHub/email). Same tools as the open-source @quantakrypto/mcp server; source at github.com/quantakrypto/pqc-tools.

AI reasoning checks any document against known international standards before your agent acts on it.

Trust scoring for x402 endpoints — "should my agent pay this?" check_endpoint runs live diligence: x402 spec-compliance probe, price sanity vs market percentiles, payTo wallet on-chain activity (Base), directory presence, infra hygiene. Returns 0-100 score with per-check evidence. compare_price positions any price vs category market data. Pay-per-call via x402: $0.02/call USDC on Base, no account or API key. tools/list free.

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.
