Output
A human-readable explanation of the specified Base blockchain transaction, including details about what type of activity occurred (e.g. swap, transfer, mint, contract interaction), amounts, addresses involved, and outcome.
Example use cases
Decode DeFi swap transaction
“I just made a swap on Base and want to understand what actually happened — can you explain this transaction hash for me: 0xabc123def456789012345678901234567890abcdef1234567890abcdef123456?”
Audit wallet activity
“My wallet sent a transaction on Base yesterday and I need to know exactly what it did — please explain hash 0xdeadbeef1234567890abcdef1234567890abcdef1234567890abcdef12345678.”
Verify NFT mint transaction
“Can you look up this Base tx hash and tell me whether it was a successful NFT mint and what the details were: 0x9f8e7d6c5b4a3210fedcba9876543210fedcba9876543210fedcba9876543210?”
Technical details
Endpoint
GEThttps://geld-machen-x402.fly.dev/product/base-tx-explain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a specific Base network transaction hash and need a plain-English explanation of what occurred on-chain. Prefer this over a generic block explorer when you need structured, agent-consumable output rather than a UI. Best suited for Base (Coinbase L2) transactions specifically, not Ethereum mainnet or other chains.
Side effects
- Invalid or malformed transaction hash (missing 0x prefix or wrong length) returns an error
- Transaction hash not found on Base network returns not-found error
- Network or RPC timeout causes delayed or failed response
- Response schema is empty so exact error format is undocumented
