# AmanChain Transaction Lookup

> AmanChain Transaction Lookup is a paid API for AI agents from preview-chat-701ec510-82d7-4ee3-ae9d-8fdb8c4f421b.space-z.ai, paid per call via x402, $0.031104/call, status unknown (last checked 2026-09-15).

Looks up on-chain transaction details by hash or ID against live consensus state, paid per call via x402 in USDC on Base.

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 amanchain-transaction-lookup-86e7c7f9 -d '<json body>'
```

Example prompt: Can you look up the details for transaction hash 0xabc123...def on the blockchain — I want to know its status, the sender and receiver, the value transferred, and how many confirmations it has?

## When to prefer this

Choose this endpoint when you need deterministic, node-executed transaction lookups against live blockchain consensus state without requiring an API key or account setup. It is ideal for agents that need pay-per-use on-chain transaction verification settled in USDC via x402, especially in scenarios where traditional block explorer APIs are unavailable or require registration.

## Known failure modes

- Transaction hash not found on chain — returns error or empty result
- Invalid or malformed transaction hash format
- Network congestion causing delayed response from node
- Transaction exists on a different chain than queried
- Insufficient x402 payment resulting in 402 response
- Node temporarily unavailable or out of sync with consensus

## How this service works

Transaction Lookup: node-operated on-chain service Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-tx-lookup","request":"<input>"}. No account, no API key.

## Output

Returns structured on-chain transaction details including transaction status (confirmed/pending/failed), block number, sender and recipient addresses, value transferred, gas used, transaction fees, number of confirmations, and timestamp — sourced from live blockchain consensus state.
