Put up to three indexed A2A agents or paid APIs side by side. Compare the evidence we hold, then open the full record or choose an alert. No account required to compare.
These are stored observations, not a fresh live test or a security certification. Probe success measures conclusive checks in a rolling 30-day window; it is not task success or an uptime SLA. A valid signature proves integrity against a signing key, not operator identity or safe behavior. A declared payment rail does not prove settled revenue.
Enterprise adds deeper comparisons of observed inflow, caller mix and skills. Public evidence above stays free.
