That sounds like a finance problem, but it is really a builder workflow problem. If an agent can browse, call APIs, compose requests, retry failures, and chain tools together, then payment becomes part of the execution graph. The payment step needs the same things builders already expect from code review and production automation: scoped permissions, predictable limits, clear ownership, and logs that make sense after the fact. That is the lens I used for this FluxA field note.…
