How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a paginated list of internal transactions for the given address on the specified EVM network. Each entry includes the transaction hash, date/time, from and to addresses (with ENS name, contract flag, scam flag), call type (call/staticcall/delegatecall), native ETH value transferred, success status, and any error. Also returns the data source (Blockscout explorer URL) and a has_more flag for pagination.
Example use cases
DeFi contract audit on Arbitrum
“Pull the internal transactions for the contract 0xUniswapV3Pool... on Arbitrum so I can see which sub-calls it's making, whether they're succeeding, and what ETH is being moved internally.”
Wallet sub-call tracing on Ethereum
“Get me the last 20 internal transactions for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum mainnet — I want to know what contracts it's interacting with under the hood and whether there were any errors.”
Scam detection via internal call analysis
“Fetch internal transactions for the address 0xAbC123... on Polygon and flag any that came from addresses marked as scams — show me the full list with contract names and call types.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/evm-internal-txs?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need sub-call (internal) transaction history for an EVM address — not just top-level transactions — across Ethereum, Base, Arbitrum, Optimism, Polygon, or zkSync. It is backed by Blockscout and enriches each call with ENS names, contract flags, and scam signals, making it ideal for DeFi auditing, contract tracing, and security analysis. Prefer it over raw RPC calls when you need structured, enriched, paginated internal tx data without running your own node.
Side effects
- Invalid or malformed EVM address returns an error
- Unsupported network value returns a validation error
- Address with no internal transactions returns an empty internal array
- Rate limiting or payment failure may return a 402 or 429 error
- Network congestion or Blockscout indexer lag may return stale or incomplete data
