Verify scraped data against the live source page. Signed verdicts, $0.01 via x402.

Check that your AI is being logical. Free tool that mathematically catches contradictions in agent reasoning. No account needed. Also offers paid guardrails that converts natural language to formal verification proofs, that anyone can check succinctly.

MCP tool observatory: do registry servers answer, and are their answers true? No key.

Estimated game fps for any GPU or Apple Silicon chip, with the limiter and tweaks.

Grade MCP servers A to F with the open behavioral litmus. npm: full toolset; hosted: lookups only.

Check if your MCP server is ready to publish on the MCP Registry, Smithery, or npm.

Runs your code against a contract; returns HELD or BROKE at the exact input. Deterministic.
