## 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-token-transfers-lookup-dfc9fbd6 -d '<json body>'
```

Example prompt: Pull all token transfers for wallet 0xAbC123...def456 from block 18000000 to 18500000, sorted ascending, across these contracts: [0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48], and return up to 100 results.

## When to prefer this

Use this endpoint when you need historical token transfer data for a specific wallet address on a supported blockchain network, especially when filtering by contract address or block range. Prefer this over general transaction endpoints when your focus is token movements (ERC-20, ERC-721, etc.) rather than native currency transfers or smart contract calls. The pay-per-call x402 model makes it cost-effective for low-frequency lookups without a subscription.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result set
- Invalid block numbers (fromBlock/toBlock) may return an error or unexpected range
- Expired or invalid pageKey causes pagination failure
- Unsupported contract address formats cause query errors
- Rate limiting or payment failure (x402) blocks the request
- Empty result set returned when no transfers exist for the given parameters

## 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 for the specified owner address, each including sender, recipient, token contract, amount, block number, and transaction hash. Also returns a pagination key (pageKey) when more results are available beyond the requested maxCount.
