## 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 phantom-api-unichain-token-transfers-28db0d57 -d '<json body>'
```

Example prompt: Pull all token transfers for wallet 0xAbC123...def on Unichain from block 1000000 to 1500000, sorted oldest-first, and limit it to 50 results — check contracts 0xToken1... and 0xToken2... only.

## When to prefer this

Use this endpoint when you need token transfer history specifically on the Unichain network and want to filter by owner wallet, token contract addresses, and/or block range. Prefer this over generic blockchain explorers when you need programmatic, paginated, pay-per-call access without API key setup, or when building agents that process Unichain token activity at scale.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Invalid block range (fromBlock > toBlock) may return an error
- Unknown contract address returns empty transfers array
- Invalid pageKey causes pagination error or empty result
- Network unavailability returns a 5xx error
- Missing required fields (e.g. owner) may return a validation error
- Rate limits or payment failures return 402 or 429 status

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a list of token transfer events on Unichain matching the query criteria, including sender, receiver, token contract address, value transferred, transaction hash, and block number. May also include a pagination key for fetching subsequent pages.
