    "description": "Describe a goal and a budget; get back a concrete plan of real x402 calls that would accomplish it — exact URLs, HTTP methods, request shapes, per-step prices from the merchants' own 402 challenges where we have verified them, alternates for every step, and a total you can check before committing. Only services that publish a callable request shape are planned; a step with no invokable candidate is returned as an explicit gap rather than a URL and a shrug. IT DOES NOT SPEND: this compiles the plan and stops, so you execute it with your own wallet on your own terms. It also does not claim the pipeline type-checks — roughly 5% of the x402 economy publishes schemas, so most step-to-step handoffs cannot be verified, and every edge says which it is.",
