xpay scored OnPay as agent-ready: every advertised plan is self-serve with public pricing. OnPay's pricing URL resolves, but plan structure is not surfaced clearly enough for an agent to enumerate without hand-parsing. No per-unit price was found on the page; an agent has no direct way to estimate the cost of a single task. All advertised paths route to a sales conversation rather than a self-serve checkout. Public API documentation is reachable without an auth wall. For the full purchase simulation see the linked Agent-Ready Index scorecard.
