SYNOPSIS

Content-Type: application/json
X-PAYMENT: <signed-transferWithAuthorization>
{ ... }↳ first call →
402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.DESCRIPTION
Decodes an EVM transaction and explains it in plain English, in one call. Composite: one call runs tx-receipt-decode + crypto-tx-explainer in parallel and merges decoded event logs (ERC-20/ERC-721 transfers, approvals, verified-ABI events) with an LLM-written plain-English summary of what the transaction did. Includes status, gas, from/to/value, and per-component telemetry. The explainer is optional and degrades on timeout without failing the call. Data-only aggregation; no advice. Use it as an EVM tx data pack, tx debug bundle, or Basescan + Etherscan tx reader.
