How this service works

Look up an Ethereum transaction by hash: sender, recipient, value in ETH, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use eth_receipt, for emitted events eth_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged.

Output

A JSON object containing the transaction hash, from/to addresses, ETH value, gas limit, block number, chain name and chain ID, nonce, the 4-byte function selector (if a contract call), and the number of input bytes.

Example use cases

Verify a payment receipt on-chain

“Someone just told me they sent me ETH with transaction hash 0xabc123... — can you look it up and confirm who sent it, how much was transferred, and that it actually went through on Ethereum?”

Audit a smart contract interaction

“I need to audit this transaction 0xdef456... — can you tell me what contract function was called (the selector), which address called it, and how many input bytes were passed?”

Trace a suspicious wallet transfer

“I'm investigating this transaction 0x789fed... on Ethereum — what's the sender address, receiver address, value transferred, and which block was it included in?”

When to prefer

Choose this endpoint when you need decoded, human-readable details of a specific Ethereum transaction by its hash, including sender, receiver, value, gas, block number, and function selector. Prefer it over raw RPC calls when you want a clean JSON response without setting up a Web3 provider or managing API keys — and payments are only charged on success.

Side effects

Invalid or malformed transaction hash returns an error
Transaction hash not found on Ethereum mainnet returns a not-found error
Network timeout or RPC node unavailability causes a failure (not charged)
Hash from a different unsupported chain may return no result
