How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with a 'success' boolean and a 'result' object containing structured details explaining what the given EVM transaction did — including transfer amounts, involved addresses, contract calls, and other decoded on-chain activity.
Example use cases
Decode a suspicious wallet transaction
“I just received a transaction on Base with hash 0xabc123...def456 and I'm not sure what it actually did — can you explain it in plain English?”
Audit a USDC payment on Arbitrum
“Can you look up transaction 0x99d8...1122 on Arbitrum and tell me what happened — specifically whether it was a USDC transfer and for how much?”
Verify a smart contract interaction on Polygon
“I need to understand what this Polygon transaction did — the hash is 0xdeadbeef...cafe0001 — was it a contract call and if so what function was invoked?”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/tx/explain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a human-readable or structured explanation of a specific EVM transaction identified by its hash, especially across a wide range of supported networks (Base, Ethereum, Arbitrum, Optimism, Polygon, BNB, Avalanche, Gnosis, Linea, Scroll, Celo, Mantle). Prefer this over block explorer scraping when you need programmatic JSON output rather than an HTML page.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on specified network
- Unsupported network name causes validation failure
- Missing required 'hash' query parameter returns error
- Network congestion or RPC timeout causes delayed or failed response
