## 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 vextorium-evm-transaction-transfers-lookup-76e565f6 -d '<json body>'
```

Example prompt: Can you look up the transaction 0x9de0044cbae3b8df09402ca5a6ac348c307e68918216a0b2d35133811bef03b8 on Base and tell me what tokens were transferred, the gas fee paid, and whether it succeeded?

## When to prefer this

Use this endpoint when you need complete transfer-level details for a single EVM transaction across Base, Ethereum, Arbitrum, Optimism, or Polygon — including token transfers, NFTs, gas fees, and status — paid per-call in USDC without a subscription. Prefer it over block explorer UIs when you need structured, machine-readable output for agent workflows, payment verification, or on-chain audit tasks.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction not found on the specified network
- Network not specified or defaults may not match the actual chain the tx is on
- Hash belongs to a different chain than the one specified
- API returns null fields if the transaction is still pending or unconfirmed
