Questions about Meta-ExternalTest
How do you detect Meta-ExternalTest?
Meta-ExternalTest signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from Meta; a copied user agent without the signature does not.
What is Meta-ExternalTest?
Meta-ExternalTest is an AI agent from Meta that works in a browser and signs its requests.
Does Meta-ExternalTest identify itself?
Yes. Meta-ExternalTest signs its requests cryptographically, which is the strongest way an agent can identify itself.
Can a bot pretend to be Meta-ExternalTest?
Not convincingly. A bot can copy Meta-ExternalTest's user agent, but without Meta signing keys its requests fail verification and it is not labeled Meta-ExternalTest.
How common is Meta-ExternalTest?
Very uncommon. Rare, brand new, or not seen on Verisoul traffic yet.
What does the Verisoul API return for Meta-ExternalTest?
Every session Verisoul identifies as Meta-ExternalTest carries an agent block with id "meta_externaltest", name, provider, type "ai_agent", detection_method "signed" and the detection_signals used (cryptographic, behavioral). Build rules on the id, type and detection method.
