How this service works
Full Ethereum transaction details by hash via eth_getTransactionByHash - from, to, value, calldata, block
Output
Returns a JSON object with the full transaction details including from address, to address, ETH value transferred, calldata/input data, gas fields, nonce, block number, and transaction index — as returned by eth_getTransactionByHash on the specified EVM network.
Example use cases
Audit suspicious wallet transfer activity
“I just noticed a weird transaction on my wallet — can you look up 0x7f2c9e1a5d8b6f4e3c2a1b9d7e5f8c3a to see who sent it, where it went, how much value transferred, and what the calldata shows?”
Verify smart contract interaction details
“My user is asking about a transaction they made on Base network, hash 0x9a8b7c6d5e4f3a2b1c0d9e8f7a6b5c4d3e2f1a0b — can you pull the full transaction to see what contract they called, the input data, and confirm the recipient address?”
Investigate cross-chain bridge transaction
“We need to audit a transaction on Avalanche that might be part of a bridge deposit — can you fetch 0x1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c and show me the from and to addresses, the amount, the calldata, and which block confirmed it?”
Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/tx/:hashWhen to prefer
Use this endpoint when you need raw, full transaction details (from, to, value, input/calldata, block) for a known tx hash on Ethereum or supported EVM networks (sepolia, Base, Avalanche, MegaETH). Prefer this over a receipt endpoint when you need input data or pre-execution fields rather than post-execution logs and status.
Side effects
- Transaction hash not found on the specified network — returns null or 404
- Invalid hash format (not 0x-prefixed 64-char hex) — returns validation error
- Network not supported or unavailable — returns error
- Transaction exists on a different network than specified — returns null
- RPC node timeout or rate limit — returns 5xx error
