# Blockscout Transaction Raw Trace

> Blockscout Transaction Raw Trace is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-12).

Retrieves the raw execution trace of a specific transaction on a given blockchain network via Blockscout's multichain explorer API

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockscout-transaction-raw-trace-2981113c
```

Example prompt: Can you pull the raw execution trace for transaction 0xabc123...def on Ethereum (chain ID 1) using Blockscout so I can see all the internal calls and gas usage?

## When to prefer this

Use this endpoint when you need the lowest-level raw EVM execution trace for a specific transaction — especially for debugging smart contract failures, auditing internal call sequences, or analyzing gas consumption at the sub-call level. Prefer this over higher-level transaction detail endpoints when you need the full opcode-level trace structure rather than just decoded logs or token transfers.

## Known failure modes

- Invalid or unknown transaction hash returns empty array or 404
- Unsupported chain_id returns an error or empty response
- Transaction not yet indexed by Blockscout returns 404 or empty
- Network latency or Blockscout node unavailability causes timeout
- Transactions on chains that don't support trace APIs may return empty traces

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

Returns an array of raw trace objects for the transaction, each containing: trace type, action details (from/to addresses, gas limit, input data, value transferred, call type or init code), result (output data, gas used), number of subtraces, trace address path, and the originating transaction hash.
