Mercurio's x402 provider offers a focused static security scanner for AI agent skills. Its single endpoint (/x402/services/skill-scan) detects 90+ malicious patterns — including code execution, shell injection, data exfiltration, credential theft, persistence mechanisms, prompt injection, and obfuscation — and returns a structured threat report with severity levels and line-by-line findings. Priced at $0.0200 per scan (network: base), it’s designed for CI/CD integration, pre-deployment vetting, and automated security gating of agent skills.
