SCRIPT MASTER LABS · AGENT COMMERCE INFRASTRUCTURE
"I did not build the rail. I built a booth."
A public leaderboard ranking AI agent tools on one question: can an agent actually pay it — and trust it? Every score carries a receipt. No puff, no sponsored ranks.
Each axis is 0 or 1 (● = yes, ○ = no, ● half = partial). Total scaled to /5. Unverified = 0. We do not score claimed volume — a viral post once claimed $2.59B in agent payments; we checked the receipts and 88% was one bridge contract. Receipts or it didn't happen.

Why the spread looks like this: the rubric measures agent-payability — no human checkout, onchain receipts — not feature quality. Subscription APIs lose on PAY/WALL/RCPT by design. That's the point of the board.
