Zero Address Detector
Detect the zero EVM address used as empty/burn/default sentinel. Call when validating recipients or detecting unset address fields safely. Returns boolean is_zero plus normalized address as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
