Hex to Integer
Parse 0x-hex strings into decimal integer strings for agents. Call when decoding calldata, logs, or block fields without a full ABI stack. Returns decimal integer string from hex 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.
