$0.01

USDC · per call · x402 on Base

What you get

Live Base-mainnet reads via MCP: erc20_balance (balanceOf for any token/holder, decimals-aware) and base_address_report (ETH balance, USDC balance, nonce). Answers from a real Base RPC at call time - perishable state, not a cache.

What it returns

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
