## 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-x402-address-volume-by-exchange-9da2bfaa -d '<json body>'
```

Example prompt: Pull the exchange volume history for wallet address 0xAbC123... from Arkham — I want to see how much it has deposited and withdrawn on each exchange over time.

## When to prefer this

Use this endpoint when you need granular, time-series exchange flow data (deposits and withdrawals in USD) for a specific blockchain wallet address, broken down by individual exchange. Prefer it over generic blockchain explorers when you need Arkham's entity-tagged exchange intelligence rather than raw transaction data, and when pay-per-request pricing via x402 is acceptable over a subscription model.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unknown address with no exchange activity returns empty volumes array
- Payment failure (insufficient USDC balance) results in 402 response and no data
- Rate limiting or authentication errors if x402 payment header is missing or invalid
- Address on an unsupported chain may return no data

## How this service works

Get Arkham transfer volume for an address. $0.20 per call.

## Output

A JSON object keyed by wallet address, containing an array of time-stamped entries. Each entry includes a timestamp and an array of volume records per exchange, with fields for exchangeID, exchangeName, depositedUSD, and withdrawnUSD.
