What you get
Receive-only Base mainnet wallet balance API. Returns official USDC balance in raw and exact decimal units plus native ETH balance, all pinned to one observed block. Submit JSON {"address":"0x..."}. No signer, API key, account access, or private data is used.
Coherent Base-mainnet wallet balances at one block; x402 price is derived from the endpoint's verified 402 challenge.

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.
