You: "Discover what's available at $example.com"

Claude: [Uses path402_discover to probe the $address]
        Found 3 nested tokens:
        - $example.com/$blog (500 sats, 0 supply)
        - $example.com/$api (1000 sats, 0 supply)
        - $example.com/$premium (2500 sats, 0 supply)

You: "Evaluate if $example.com/$blog is worth acquiring"

Claude: [Uses path402_evaluate and path402_economics]
        ROI Analysis:
        - Current price: 500 sats
        - Breakeven: 1 serve at current rates
        - Projected ROI: 340% over 30 days
        Recommendation: ACQUIRE (high confidence)

You: "Acquire 10 tokens"

Claude: [Uses path402_acquire]
        Acquired 10 $example.com/$blog tokens
        Total cost: 5,000 sats
        New balance: 10 tokens

$example.com              → Site-level token
$example.com/$api         → API access token
$example.com/$api/$premium → Premium tier token
