x402
utility

Sniff PDF magic and approximate size from base64 prefix. Call when rejecting non-PDF uploads before heavy OCR. Returns is_pdf and decoded_prefix_len 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.
