## 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-soneium-token-transfers-9420240a -d '<json body>'
```

Example prompt: Pull all token transfers for the Soneium wallet 0xAbC123... from block 1000000 to 2000000, sorted in descending order, and show me up to 50 results.

## When to prefer this

Use this endpoint when you need historical token transfer data specifically on the Soneium network, with flexible filtering by owner, block range, and contract address. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access without API key registration and want structured JSON output suitable for agent workflows.

## Known failure modes

- Invalid owner address format returns an error
- Unknown or malformed contract address in contractAddresses array causes rejection
- Invalid block number strings for fromBlock/toBlock result in query errors
- Payment not provided or insufficient USDC causes x402 payment-required rejection
- No transfers found for the given parameters returns an empty result set
- pageKey from a previous query no longer valid if chain state has changed

## 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

A paginated list of token transfer events on the Soneium network, each including sender, recipient, token contract address, amount, block number, and transaction hash. A pageKey is returned when additional results are available.
