# CRA AGENT Arc Transaction Detail

> CRA AGENT Arc Transaction Detail is a paid API for AI agents from api.cra-agent.tech, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Returns status, sender, recipient, fee, and all ERC-20 token transfers for a given Arc transaction hash, with symbols and human-readable amounts.

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 cra-agent-arc-transaction-detail-f3dfc0ef
```

Example prompt: Can you look up the Arc transaction 0x903a75fb579f4f6eb6b7ffb90ff3f7de405f117e9aed78d1f21c23a0f1fa0250 and tell me who sent it, who received it, what tokens were transferred, and what the fee was?

## When to prefer this

Use this endpoint when you need comprehensive details about a specific Arc transaction by hash — particularly when you need token transfer breakdowns with human-readable amounts and USDC fee data. Prefer this over generic EVM explorers when working specifically on the Arc network, or when you need parsed ERC-20 transfer data rather than raw log data.

## Known failure modes

- Missing or invalid 'hash' query parameter returns a 400 error
- Non-existent or unindexed transaction hash returns a 404 or empty result
- Arc node unavailability may cause timeouts or 503 errors
- Payment required (402) if x402 payment header is not provided or USDC balance is insufficient

## How this service works

Status, sender, recipient, fee in USDC and every ERC-20 transfer in an Arc transaction, with symbols and human-readable amounts.

## Output

Returns a structured object containing the transaction status (success/failure), sender and recipient addresses, the fee in USDC, and a list of all ERC-20 token transfers in the transaction — each with token symbol, contract address, from/to addresses, and human-readable amount.
