node or ABI decoder locally. It is particularly useful for AI agents performing safety checks before signing transactions, wallets rendering human-readable transfer previews, or audit pipelines flagging suspicious transfers. At $0.01 USDC per call via x402, it is cost-effective for on-demand single-transfer decoding on the Base network.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-13T13:07:14.038Z","isFirstParty":false}
