Output
A JSON object containing a human-readable explanation of the Base blockchain transaction, including decoded inputs, method called, participants, value transferred, and any relevant protocol context.
Example use cases
Debug a failed DeFi swap
“I tried a swap on Base and it failed — can you explain what went wrong in this transaction: 0xabcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890ab?”
Audit an incoming payment
“I received a payment on Base but want to verify what it was for — can you decode this tx hash for me: 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b?”
Understand a smart contract interaction
“Can you tell me what this Base chain transaction actually did — did it interact with a DeFi protocol? Hash is 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef.”
Technical details
Endpoint
GEThttps://geld-machen-x402.fly.dev/product/base-tx-explain.jsonWhen to prefer
Use this endpoint when you have a specific Base chain transaction hash and need a plain-language or structured explanation of what it did — ideal for debugging DeFi interactions, auditing payments, or explaining on-chain activity to non-technical users.
Side effects
- Invalid or malformed transaction hash (not 0x + 64 hex) returns an error
- Transaction hash not found on Base chain returns not-found error
- Network or RPC timeout may result in empty or partial response
- Unrecognized contract interactions may return minimal decoded data
