# Heurist Mesh: EtherscanAgent Transaction Details

> Heurist Mesh: EtherscanAgent Transaction Details is a paid API for AI agents from mesh.heurist.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Analyzes a specific Ethereum blockchain transaction by ID, returning sender, receiver, gas fees, and decoded transaction actions like DEX trades or DeFi interactions.

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 heurist-mesh-etherscanagent-transaction-details-20804162 -d '<json body>'
```

Example prompt: Can you tell me exactly what happened in Ethereum transaction 0x4e3a3754410177e6937ef1f84bba68ea139e8d1a83225e8e3a0e9b6b4c8f5e2d — who sent it, who received it, what DeFi action was taken, and what the gas fees were?

## When to prefer this

Use this endpoint when you need to understand exactly what a specific Ethereum transaction did — particularly for decoding DeFi or DEX activity. Prefer this over wallet analysis endpoints when you have a specific tx hash and need granular per-transaction detail rather than aggregate wallet history.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Ethereum mainnet
- Network timeouts when Etherscan API is slow or rate-limited
- Transaction too recent and not yet indexed
- Payment of $0.01 USDC via x402 required or call is rejected

## How this service works

Analyze a specific blockchain transaction. Provides detailed information about the transaction including sender, receiver, gas fees, and transaction actions (such as trading on DEX, interacting with DeFi). Use this tool when you want to know what exactly happened for a transaction id.

## Output

Returns structured details about the specified Ethereum transaction, including the sender and receiver addresses, gas fees paid, block information, and decoded transaction actions such as token swaps on DEXes (e.g. Uniswap), liquidity provision, or other DeFi protocol interactions.
