Text SHA-256 API for agents
SHA-256 hex digest of UTF-8 text. Call when content addressing or dupe keys for text. Returns sha256 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.
