# Xerxes Ethereum Transaction by Hash

> Xerxes Ethereum Transaction by Hash is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-02).

Fetches full transaction details for a given Ethereum transaction hash via JSON-RPC eth_getTransactionByHash.

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 xerxes-ethereum-transaction-by-hash-2f93f27b
```

Example prompt: Can you pull up the full details for Ethereum transaction 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060 — I want to see who sent it, who received it, the value, and the gas price?

## When to prefer this

Use this endpoint when you need the raw, complete transaction record for a specific Ethereum mainnet tx hash — including sender, recipient, value, input calldata, gas parameters, and block placement. Prefer this over block-level or receipt endpoints when you need pre-execution transaction fields (not gas used or logs, which require eth_getTransactionReceipt).

## Known failure modes

- Transaction hash not found (unconfirmed or invalid hash) — returns ok: false with an error message
- Malformed hash (not 0x + 64 hex chars) — rejected by input schema validation
- Transaction is pending and not yet mined — result may be null
- Network or RPC node error — ok: false with provider error details
- Payment failure via x402 — request blocked before reaching the RPC

## How this service works

Returns the transaction details for a given transaction hash on Ethereum. Includes fields like from, to, gas, gasPrice, value, input, blockNumber, transactionIndex, etc. Query: hash (transaction hash, 0x + 64 hex).

## Output

A JSON object containing the full Ethereum transaction record as returned by eth_getTransactionByHash: from, to, value (in wei), gas, gasPrice, input, blockNumber, blockHash, transactionIndex, nonce, hash, and v/r/s signature components. Returns ok: true with a result object on success, or ok: false with an error string on failure.
