Example use cases
Wallet internal transfer audit
“Show me the internal transactions for Ethereum address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe on ETH — get the first 20 and then the next page so I can audit all the internal ETH moves.”
Smart contract internal call tracing
“I need to trace internal transactions for the Uniswap V2 router contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on the ETH network — fetch up to 50 results starting from page 0.”
Suspicious wallet activity investigation
“Can you look up internal transactions for Ethereum address 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD on ETH? I want to see the second page of 20 results to check for unusual internal transfers.”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/eth/address/internal-transactions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need internal (message call) transactions for an Ethereum address — transfers triggered by smart contract execution rather than direct EOA transactions. Prefer this over generic transaction endpoints when investigating DeFi interactions, contract-to-contract calls, or tracing value flows inside complex protocols. The blockchain.com explorer gateway is a reliable choice when you need paginated, structured access to Ethereum internal transaction data with per-call micropayment pricing.
Side effects
- Invalid Ethereum address format returns an error or empty result
- Unsupported network value causes a bad request response
- Page or size out of allowed range (size > 50 or page < 0) returns validation error
- Address with no internal transactions returns an empty list
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting or gateway timeout for high-traffic addresses
