sitedex.devDeveloper Tools

Web Bot Auth key check is a diagnostic utility that examines signing-key directories published at the /.well-known/http-message-signatures-directory path. It is built on RFC 9421 for HTTP Message Signatures and helps verifiers such as Cloudflare authenticate web crawlers or bots from those published keys.

The tool accepts either a domain name or a full directory URL as input. It then inspects each key individually for errors that would prevent successful verification, including wrong key type, incorrect curve, expiring keys, or the presence of a leaked private key. No data is stored during the process. An example directory is provided for immediate testing, and a related fetchcheck utility is mentioned for observing how a site responds to a signed crawler.

It forms part of the Sitedex platform, which serves as an interface between websites and AI agents. The page presents the checker alongside other Sitedex offerings such as payment-readiness insights, documentation, an MCP server, a CLI on npm, and an AI score feature. Access occurs through a web interface at the Sitedex site.
