How this service works
Access to api/v2/transactions/:hash. Retrieve detailed information about a specific transaction
Output
Returns a structured JSON object containing the transaction's status (success/fail/pending), block number, timestamp, from/to addresses, native value transferred, gas limit, gas used, effective gas price, total fee in native currency, decoded input data, internal transactions summary, token transfer events, and associated logs.
Example use cases
Verify a crypto payment was received
“I just sent 0.5 ETH to a vendor and they say they didn't get it — can you check transaction 0xabc123...def456 on Ethereum mainnet and tell me if it succeeded and who it went to?”
Audit DeFi trade execution
“Pull up the details for this Polygon transaction 0x9f8e7d6c... — I need to see the input data, token transfers, and exact gas cost for my accounting records.”
Debug a failed smart contract call
“This transaction 0x1234abcd... on Arbitrum seems to have failed — can you look it up on Blockscout and tell me the status, which block it landed in, and any relevant error info?”
Technical details
Endpoint
GEThttps://api.blockscout.com/:chain_id/api/v2/transactions/:transaction_hash_paramWhen to prefer
Use this endpoint when you need comprehensive, structured details about a single known transaction hash on any chain supported by Blockscout. It is ideal for verifying payment finality, auditing DeFi interactions, debugging failed contract calls, or enriching event data with on-chain facts. Prefer it over Etherscan-style APIs when Blockscout indexes the target chain, especially for EVM-compatible L2s and sidechains where Etherscan coverage is limited.
Side effects
- Invalid transaction hash format returns 400 or 422 error
- Transaction hash not found on the specified chain returns 404
- Unsupported or invalid chain_id returns 400 or routing error
- Network timeout or Blockscout node unavailability returns 500 or 503
- Rate limiting exceeded returns 429
