## 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-network-price-history-b9f95fd1 -d '<json body>'
```

Example prompt: Pull the historical price and market cap data for Ethereum from Arkham — I want to see how the USD price and 24-hour volume have changed over time.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-request access to historical price, market cap, and volume data for a blockchain network's native asset — particularly when you want Arkham's wallet-intelligence-grade data provenance and are willing to pay per call via x402 USDC micropayments rather than maintain a subscription.

## Known failure modes

- Invalid or unsupported network identifier returns an error or empty array
- Insufficient USDC balance for x402 payment results in a 402 Payment Required error
- Malformed request body returns a 400 Bad Request
- Time range with no available data returns an empty array
- Rate limiting or service unavailability returns a 5xx error

## How this service works

Get Arkham historical data for a blockchain network. $0.20 per call.

## Output

A JSON array of historical data points, each containing a USD price, ISO 8601 timestamp, market cap in USD, and 24-hour trading volume in USD for the specified blockchain network.
