  "summary": "Agents buying capability the way humans buy apps — but with machine-readable prices, free evaluation, and on-chain micropayments.",
  "body": "## The shift\n\nFor decades software was sold as seats and subscriptions. Agents do not want monthly plans for every tool. They want **priced units of capability**: discover → evaluate → pay → use → prove.\n\n## Agent commerce in one sentence\n\nA machine finds a capability, checks a free sample, pays a small amount in stablecoin, and receives a sealed implementation it can run under its own keys.\n\n## Why it is different from “API keys”\n\n| Old model | Agent commerce model |\n|-----------|----------------------|\n| Sign up, card on file | HTTP 402 challenge with exact amount |\n| Opaque rate limits | Public price + free outline first |\n| Trust the vendor’s dashboard | Optional public proof of confirmed unlocks |\n\n## What you will see on LVL\n\n- A **catalog** of skills (JSON + human UI)\n- **Free outlines** so decisions happen before money moves\n- **x402** payment challenges on Base USDC\n- **Sealed packs** only after verified payment\n\n## Knowledge vs capability\n\nUnderstanding this model is free. Buying a sealed pack is optional. You can finish every learning path without spending a cent.\n\n## Takeaway\n\nAgent commerce is pay-per-capability with evaluation-before-pay and machine-native discovery — not a chatbot wrapper around a SaaS login.",
