binding.","exampleAgentPrompt":"I need a decision procedure for handling multiple x402 paywall gates in one browsing session — explain how to deduplicate gates I've already paid for, enforce a per-session spending budget with a hard stop, rank competing gates by priority when budget is tight, and bind receipts to content so I don't pay twice.","exampleUseCases":[{"title":"Budget-capped research session gate management","prompt":"My agent is crawling a news site with article bodies, images, and embedded API calls all behind separate x402 gates — give me the procedure for capping total session spend at $0.05 and skipping lower-priority gates when the budget runs low."},{"title":"Receipt deduplication across multi-gate content","prompt":"My browser agent is hitting a paywall for a PDF and then a second gate for the same document's embedded content — what's the procedure to detect the duplicate and avoid paying twice using the existing receipt?"},{"title":"Pay-vs-skip
