A deterministic Base wallet card for any address: EOA or contract, ETH balance, first seen and last activity, transaction and token-transfer counts, up to 20 ERC-20 holdings by value, and rule-based flags (fresh wallet under 7 days, dormant over 180 days, no ETH, single token, contract address), from Blockscout and the Base RPC. No labels, no scoring, no LLM. Facts an agent can act on; informational only. Price $0.05 per call, paid with USDC over x402.
