EVM Transaction Explainer

blockchain

Serving

Explains an EVM transaction in plain language: decoded intent, asset movements, approvals, and risk flags. POST /v1/tool with {tx_hash, chain_id}, or GET /v1/explain with query params, and get one JSON object with a summary, moved assets, gas, parties, and risk flags. Deterministic for identical input. Pay per request in USDC; no account, no API key.

Request schema

{
  "type": "object",
  "description": "A transaction to explain. On the MCP relay route POST /v1/tool these fields are wrapped under an `arguments` object; the direct route takes them at the top level. GET /v1/explain takes the same fields as query parameters.",
  "properties": {
    "tx_hash": {
      "type": "string",
      "description": "The transaction hash, 0x-prefixed."
    },
    "chain_id": {
      "type": "integer",
      "description": "EVM chain id (default 1)."

Response schema

{
  "type": "object",
  "description": "For POST /v1/tool (and GET /v1/explain), a JSON object with a plain-language summary, moved assets, gas, parties, risk flags, and the chain_id as received. The exact shape is the service's own and is not pinned here; errors return a JSON object with an `error` field, and the GET routes return their own small JSON documents."
