EVM Hex Data Normalize API for agents
EVM Hex Data Normalize: normalizes even-length EVM hex data while preserving byte boundaries using only bounded caller-supplied values. Call when you need a bounded evm hex data normalize result 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 Hex Data Normalize as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. 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.
