How this service works
Base tx receipt + decoded calldata (?tx=0x...)

Example prompt
“Can you decode the transaction receipt for tx hash 0xabc123... on Base (chain eip155:8453) and tell me what function was called, the parameters, and whether it succeeded?”
Technical details
Endpoint
GEThttps://lionx402.com/api/x402/tx-receipt-decoded-jsonWhen to prefer
Use this endpoint when an AI agent needs to programmatically decode and verify what a specific blockchain transaction did — especially on Base or Ethereum — without holding an API key. Ideal for post-payment verification workflows, auditing USDC transfers, or confirming smart contract interactions in agent pipelines that pay per call via x402.
Side effects
- Invalid or malformed transaction hash returns error
- Transaction not found on specified network returns empty or error response
- Unsupported network/chain ID returns error
- Payment not confirmed via x402 results in 402 response blocking the call
- Calldata decoding may fail for unknown or unverified contract ABIs, lowering confidence score
