x402
EVM Internal Transaction Tracer is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Lists the internal transactions (nested contract calls, value transfers, and call types) of a given EVM transaction hash via Blockscout

How this service works
List the internal transactions of an EVM transaction: the nested contract calls and their value transfers and call types, via Blockscout. Reveals the value flow and call tree that a plain receipt hides. Rate-limited upstream degrades gracefully rather than erroring.
Output
A structured list of internal transactions within the given EVM transaction, including each nested contract call, its type (call, delegatecall, etc.), the from/to addresses, value transferred, and the hierarchical call tree showing how execution flowed between contracts.
Example use cases
Example prompt
“Can you show me all the internal transactions and nested contract calls for Ethereum transaction 0x4e3a3754410177e6937ef1f84bba68ea139e8d1f1f7f8af234b6fde7a9f6a86? I want to understand the full call tree and value transfers hidden inside it.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/evm/internal-txWhen to prefer
Use this endpoint when you need to understand what actually happened inside a complex EVM transaction beyond what the top-level receipt exposes — particularly for DeFi swaps, multi-hop calls, proxy contracts, or debugging unexpected ETH movements. Prefer this over a basic transaction lookup when the call tree and internal value flow are needed.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified network
- Rate limiting from upstream Blockscout degrades gracefully rather than returning an error
- Unsupported network name returns validation error
- Transaction has no internal calls, returning an empty list
