Check the signed requests (Web Bot Auth)
Exa signs every ExaSearchBot request with HTTP Message Signatures (RFC 9421), so the check holds regardless of IP address. crawler.exa.ai/.well-known/http-message-signatures-directory
Is this really ExaSearchBot?
Signed requestsExa signs each ExaSearchBot request with HTTP Message Signatures (RFC 9421), so its address proves nothing. A genuine request carries Signature, Signature-Input and Signature-Agent headers, and the signature checks out against Exa’s published keys.
Many CDNs, Cloudflare included, check these signatures for you and mark the request as a verified bot. Without a signature, it isn’t ExaSearchBot.

If ExaSearchBot is not named in robots.txt, Exa says it follows your rules for major search engines, then the * group. Robots.txt controls crawling, not indexing: use a noindex meta tag or X-Robots-Tag header to remove a page from Exa’s index.
