# DDG Ethereum Transaction Trace

> DDG Ethereum Transaction Trace is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-14).

Traces an Ethereum transaction by hash, returning detailed execution trace data for the specified tx

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/ethereum/trace/tx
- Price: $0.004/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ddg-ethereum-transaction-trace-96283eaf
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_jdL2Ttd88ygWIW5qG2exj

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 ddg-ethereum-transaction-trace-96283eaf -d '<json body>'
```

Example prompt: Can you trace this Ethereum transaction for me and show me the full execution call stack — tx hash 0xabc123def456... — I want to see all the internal calls and what happened step by step.

## When to prefer this

Use this endpoint when you need detailed execution trace data for a specific Ethereum transaction, particularly to debug smart contract interactions, inspect internal calls, or audit on-chain behavior. Prefer this over block explorers when you need machine-readable structured trace output payable per-call via USDC with no account setup.

## Known failure modes

- Invalid or malformed transaction hash returns an error response
- Transaction not found on Ethereum mainnet returns empty or error result
- Network or RPC timeout causes delayed or failed response
- Malformed request body (missing required fields) returns 400-level error
- Payment failure via x402 results in 402 response before trace is executed

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a JSON object with ok:true and detailed trace data for the specified Ethereum transaction, including internal call stack, execution steps, gas consumption, and sub-call outcomes for the given tx hash.
