Broken input?
Spot missing JSON fields, inconsistent CSV rows and unexpected schema changes before an agent acts on them.
Run JSON GuardCatch data and integration errors before they reach production.
Small, deterministic checks for developers and AI agents. Inspect JSON, CSV, invoices, API contracts, MCP metadata and schema drift. Use REST or a public Streamable HTTP MCP server.
Uncertain API integration?
Inspect supplied OpenAPI metadata and MCP registration documents without executing third-party code.
Check an API contractWrong calculated totals?
Recalculate sample invoice line totals with decimal arithmetic; no claim of legal or tax certification.

Transparent by design
All nine validators work on supplied data in memory. Only CVE Verify queries the official NIST NVD database. The public experiment has usage limits and no billing. The tools are advisory and cannot certify security, regulatory compliance or factual truth.
Use synthetic or public examples. Never submit credentials, personal information, private invoices or production records. The demo does not need registration.
