## 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 sitecheck-evm-token-transfer-history-f8bd4e8f
```

Example prompt: Show me the last 500 blocks of USDC transfers (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) for the wallet 0xb2cc224c1c9feE385f8ad6a55b4d94E92359DC59 on Base — I want to see who sent funds in and out.

## When to prefer this

Use this endpoint when you need to fetch ERC-20 token transfer history for a specific EVM wallet on Base, Ethereum, Arbitrum, Optimism, or Polygon without running your own node. It is ideal for on-chain auditing, wallet activity monitoring, and DeFi analytics use cases where you need structured transfer data including direction, counterparty, and decoded token amounts quickly via a pay-per-call API.

## Known failure modes

- Invalid EVM address format returns an error response
- Unsupported chain name returns an error
- Block range exceeding 10000 blocks is rejected
- Invalid or non-ERC-20 token contract address returns empty or error
- RPC node unavailability may cause timeout or partial results
- Address with no transfers in the specified window returns an empty transfers array

## How this service works

ERC-20 transfers into and out of an address in a window of recent blocks (default 2,000, max 10,000), from Transfer logs, newest first, max 100 rows with token symbols. token limits the search to one contract. A busy address can be truncated: narrow the window to see the rest.

## Output

Returns a JSON object containing the queried chain, wallet address, optional token contract, block window searched, total transfer count, and an array of transfer records. Each transfer includes sender, recipient, amount (human-readable and raw), token symbol, contract address, transaction hash, block number, direction (in/out), and counterparty address. Results may be truncated if the count exceeds limits.
