Bytes SHA-256 From Base64 API for agents
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.
