How we confirm identity

Signed
The agent signs its requests, so its identity is verified cryptographically.
Self-declared
The agent names itself in its user agent, and Verisoul confirms it with network, device or behavioral data. A user agent alone is never enough.
Inferred
Fingerprinted from clear, repeatable patterns. No single signal proves it, but together they point to one agent.

The four signals
