Chain ID → Network Name
Map common EVM chain_id integers to short network names. Call when labeling multi-chain configs without embedding a full chainlist fetch. Returns short name and known flag for the chain_id 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.
