  "description": "EVM Access List Shape Check: EVM Access List Shape Check checks bounded EIP-2930 access-list address and storage-key shapes from bounded caller-supplied values without an external provider. Call EVM Access List Shape Check before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Access List Shape Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Uses caller-supplied values only; it performs no RPC call, signing, broadcasting, balance lookup, custody, trading, or live-chain claim. Advisory output only; the buyer owns authorization, payment policy, and production decisions.",
