Discover AI products and tools, and check how clearly your website publishes information for software.

AI Product Index

Search 51 listed products, get a free website score, or register your own product.

• Check a website — an A–F score with the results of 20 published checks.
• Find an MCP server — 16,526 catalogued remote endpoints.
• Explore x402 APIs — 15,392 catalogued endpoints with published payment terms.
• Understand the checks — what each check measures and how to address a finding.

Registration, search, catalogs and website scores are free. Catalog health comes from rotating samples and is not a live availability guarantee.

For developers

Connect through MCP or use the HTTP API. One optional paid endpoint, POST /api/audit, returns the full report with ranked fixes and snippets for $0.05 USDC per call. Payment instructions and examples are in the developer documentation.
