nbx4.dev/v1/report

Analyze a Base Mainnet token contract: block-pinned owner(), ERC-1967 proxy slots, ERC-20 metadata, code hash, best-effort source match and prior-snapshot comparison when available. Free POST /v1/prepare returns report_id; paid GET /v1/report reads it for 0.01 USDC via x402. Not a security audit.
