ExaSearchBot

Fully verifiable

Exa's search crawler, which discovers and indexes pages on the public web so that people and applications can find, retrieve and cite them through Exa. Every request is signed with HTTP Message Signatures (RFC 9421) under the Web Bot Auth scheme, so a request can be verified cryptographically regardless of its source IP address.
