Tools (paid, pay-per-call)

Tool	Price	Description
`fetch_url`	$0.01	Fetch any public URL as clean markdown or JSON
`token_price`	$0.01	Real-time USDC spot price for any EVM token
`wallet_balance`	$0.02	Native and USDC balance for any EVM wallet

Payments are handled automatically by the @x402/mcp client — the wallet simply signs the x402 settlement. No subscriptions, no keys, no API tokens.

REST fallback

The same tools are available as plain HTTP endpoints with x402 payment-required flow:

GET /fetch?url=<encoded-url> — $0.01
GET /price?address=&chain= — $0.01
GET /balance?address=&chain= — $0.02
