How this service works
Call when an agent needs status, block, gas used, effective gas price, from, to, and truncated logs for one Ethereum transaction hash. Status is success, reverted, or pending. An unknown hash errors. Read-only. No spend. Send JSON {"hash":"0xabababababababababababababababababababababababababababababababab"}. Exact $0.003 USDC on Base. Try unpaid POST /v1/sandbox/eth-tx-receipt first.
Output
Returns transaction status (success, reverted, or pending), block number, gas used, effective gas price, from address, to address, and a truncated list of event logs emitted by the transaction. An unknown or malformed hash returns an error.
Example use cases
Confirm DeFi swap settlement
“I just submitted a swap on Uniswap with tx hash 0xabababababababababababababababababababababababababababababababab — can you tell me if it succeeded, how much gas it used, and what the effective gas price was?”
Debug a failed smart contract call
“My contract interaction with hash 0xabababababababababababababababababababababababababababababababab seems to have failed — can you check its status, show me the from and to addresses, and pull any logs so I can figure out what went wrong?”
Verify an incoming payment on-chain
“Someone claims they sent me ETH in transaction 0xabababababababababababababababababababababababababababababababab — can you confirm it went through, who the sender is, and which block it landed in?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/eth-tx-receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, structured receipt for a single Ethereum mainnet transaction hash — especially status (success/reverted/pending), gas metrics, and addresses — without needing a full archival node or complex RPC setup. A free sandbox endpoint (/v1/sandbox/eth-tx-receipt) is available for testing before committing to the $0.003 USDC paid call.
Side effects
- Unknown transaction hash returns an error response
- Malformed hash (not matching 0x[64 hex chars] pattern) is rejected at input validation
- Pending transactions return 'pending' status with limited fields
- Network or upstream Ethereum node unavailability may cause transient errors
- Payment not provided or incorrect amount results in 402 rejection
