## 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 arkham-transfers-api-x402-d3970ce2 -d '<json body>'
```

Example prompt: Pull all USDC transfers sent from wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 in the last 7 days using Arkham, and show me the top recipients by amount.

## When to prefer this

Choose this endpoint when you need structured, filtered on-chain transfer data enriched with Arkham's entity intelligence — especially useful for tracing fund flows, investigating specific wallets or named entities, or analyzing token-specific transfer history. Prefer it over raw blockchain RPC calls when you need entity-labeled data rather than anonymous addresses. Note the high per-call cost ($1000 USDC) makes it best suited for high-value investigative or compliance workflows.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported token symbol may return no results or an unrecognized token error
- Overly broad queries without filters may time out or return truncated results
- USDC payment failure ($1000/call) will block the request via x402 protocol
- Date range out of supported historical bounds may return empty results
- Unknown entity name returns no results if Arkham has no label for it

## How this service works

Get Arkham transfers with filters

## Output

Returns a list of on-chain transfer records matching the specified filters, each including sender and receiver addresses, entity labels (where Arkham has identified them), token type, transfer amount, transaction hash, block number, and timestamp.
