How this service works
Internal transactions of an EVM address (native coin moved by contracts, invisible in the normal history): date, type, from, to, value, success and parent transaction.
Output
Returns a list of internal transactions for the queried address, each containing: transaction date, type, from/to address objects (with ENS name, contract flag, and scam flag if available), native value transferred, success/failure status, parent transaction hash, and whether more results exist. Also returns the queried address, network name, and data source.
Example use cases
Debug missing ETH from DeFi protocol
“I deposited ETH into a DeFi protocol but my wallet balance dropped more than expected and there's no clear transaction for it — can you pull the internal transactions for 0xAbCd...1234 on Ethereum so I can see what contract-triggered transfers happened?”
Portfolio reconciliation for hidden transfers
“I'm trying to reconcile my wallet's ETH balance on Base — can you retrieve all internal transactions for 0xDeFi...5678 on Base so I can account for any native coin movements triggered by contracts?”
Audit smart contract fund flows
“I need to audit how this smart contract at 0xCafe...9999 has been moving funds on Polygon — please get its internal transactions so I can see every contract-initiated native coin transfer, who sent it, who received it, and whether each one succeeded.”
Technical details
Endpoint
POSThttps://api.vextorium.com/evm-internas-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to surface native coin transfers that are invisible in the standard transaction history because they were triggered by smart contract execution (internal calls). It is essential for DeFi portfolio reconciliation, smart contract auditing, and debugging unexplained balance changes across Ethereum, Base, Arbitrum, Optimism, Polygon, and zkSync.
Side effects
- Invalid or malformed EVM address returns an error
- Unsupported network name causes validation failure
- No internal transactions found returns an empty list
- Rate limiting or payment failure if x402 payment not completed
- Node provider downtime may cause temporary unavailability
