Bot verification now supports Web Bot Auth protocol
Vercel's Bot Protection system now supports Web Bot Auth, an IETF protocol that uses public-key cryptography to verify legitimate bot traffic from dynamic sources. This enables bots like SEO crawlers and AI services to authenticate via signed headers while blocking spoofed traffic.
We collaborated with industry partners to advance the IETF proposal for and supports the new protocol. Now, can use to verify traffic automation from dynamic and distributed sources.Web Bot AuthVercel's bot verification systemBot ProtectionHTTP Message Signatures
Vercel maintains a comprehensive and actively curated that are verified by IP, reverse DNS, and now Web Bot Auth, which verifies bots via public-key cryptography in signed headers. This ensures that legitimate automation, like SEO crawlers, performance monitoring tools, and platform-integrated AI bots, can reliably access your site, while spoofed bots are blocked.directory of known bots
Web Bot Auth's asymmetric signature proves the authenticity of the traffic regardless of its network origin, making it ideal for bots running in dynamic or serverless environments.
Verified Bots using Web Bot Auth include signed headers to authenticate each request, allowing them to be recognized and allowed through Bot Protection and Challenge Mode. For example, using Web Bot Auth, so is now allowed.ChatGPT operator signs its requests
