How this service works
Paid AI-agent access to Blockchain.com Explorer API
Output
Returns a JSON object containing a paginated list of internal (trace-level) transactions associated with the specified Ethereum address, including details such as sender, recipient, value transferred, transaction hash, block number, and call type for each internal transaction entry.
Example use cases
Audit smart contract internal calls
“Show me all internal transactions for the Ethereum contract at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on ETH — give me the first page of 20 results.”
Wallet internal transfer history
“I need to check the internal transaction history for Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on the ETH network, starting from page 0 with 50 results per page.”
DeFi protocol trace analysis
“Fetch the internal transactions for Ethereum address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on ETH so I can analyze how value flows through this Uniswap router contract.”
Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/eth/address/internal-transactions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need internal (trace-level) transaction data for an Ethereum address specifically — i.e., value transfers triggered by smart contract execution rather than top-level user-initiated transactions. Prefer this over generic ETH RPC calls when you want paginated, pre-processed internal tx lists without running your own archive node. It is especially useful for auditing DeFi interactions, contract fund flows, or wallet activity that doesn't appear in standard transaction lists.
Side effects
- Invalid or malformed Ethereum address returns an error or empty result
- Unsupported network value results in an error response
- Page index out of range returns empty results
- Rate limiting or payment failure (x402 payment not processed) returns a 402 status
- Network timeouts or upstream node issues may cause 5xx errors
- Size parameter exceeding maximum of 50 is rejected
