Lightning doesn't just move money faster. For agents, it changes the category.

HTTP APIs get called millions of times for free. That works when humans are running software. Agents billing per tool call, routing based on cost: that needs a payment layer with no minimums, no friction.

Credit cards have a $0.30 floor. ACH settles in days. Lightning has neither.

What's actually blocking you from adding per-call Lightning billing to a tool you maintain?
