Ethereum Internal Transactions Lookup
x402
Ethereum Internal Transactions Lookup is a paid API for AI agents from x402-stock-indicators.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Returns internal (trace-level) transactions for a given Ethereum address, including contract creations, calls, and value transfers, paid per-call via x402/USDC.

How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
Returns a JSON object containing the queried address, the chain identifier, a total count of internal transactions, and an array of transaction objects each with: hash, from, to, type (e.g. 'create', 'call'), value in wei, gas used, error status, error code, block number, and ISO 8601 timestamp.
Example use cases
Audit smart contract deployment history
“Look up all internal transactions for Ethereum address 0x20d42f2e99a421147acf198d775395cac2e8b03d and tell me which ones were contract creations, when they happened, and how much gas was used.”
Trace internal ETH transfers for a wallet
“I need to see all internal value transfers into and out of the Ethereum address 0x2c1ba59d6f58433fb1eaee7d20b26ed83bda51a3 — show me the amounts in wei, the counterparties, and whether any of them errored.”
DeFi protocol interaction forensics
“Pull the internal transaction trace for Ethereum address 0xABC123... so I can see every sub-call it made, including which blocks they landed in and whether any reverted.”
Technical details
Endpoint
GEThttps://x402-stock-indicators.vercel.app/internal-transactions/%7Baddress%7DWhen to prefer
Choose this endpoint when you need trace-level (internal) transaction data for an Ethereum address — especially contract creations, internal calls, and sub-transfers that don't appear in standard ETH transfer lists. It is ideal for DeFi audits, wallet forensics, and smart contract origin tracing. Prefer it over standard transaction APIs when you need to see value flows and contract deployments that occur inside transactions, not just top-level sends. The pay-per-call x402 model makes it cost-effective for sporadic queries without requiring API key setup.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Address with no internal transactions returns an empty transactions array
- Payment failure via x402 protocol (insufficient USDC balance) blocks the call
- Network or upstream node unavailability may cause timeouts
- Non-Ethereum addresses (e.g. Solana) may not be supported on this endpoint
