Bytes SHA-256 From Base64
SHA-256 of base64-decoded bytes. Call when hashing binary payloads agents already hold as base64. Returns sha256 and nbytes 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.
