Each step names a tool and its args; later steps can reference earlier outputs via {\"$ref\": \"step_N.field\"} or {\"$prev\": \"field\"}. Saves agents the round-trip + per-call gas of N separate x402 settles when they know the chain in advance — e.g. validate email → check domain DNS → solve captcha → submit form, all atomic. Stops on first step error and returns partial results. Cheaper than the unit-call sum because it bundles.","when_to_use":null,"vs_alternatives":null,"example_request":null,"example_response":null,"settle_to":"0x3fD9ee1373562f894D322B37DFFAd7a5D2b2d78f","network":"base","facilitator":"https://facilitator.xpay.sh","payment_required":true,"free_introspection":true,"note":"GET this URL = free introspection card.
