## 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 glassnode-total-transfer-volume-on-chain-fa231d63
```

Example prompt: Pull the total on-chain transfer volume for BTC denominated in USD at a 24h resolution from Glassnode — I want to see how much Bitcoin is moving on-chain each day.

## When to prefer this

Use this endpoint when you need authoritative, Glassnode-sourced on-chain transfer volume data for major crypto assets (BTC, ETH, SOL, etc.) across multiple networks and time resolutions, especially when you need the data in both native and USD denominations with flexible interval granularity.

## Known failure modes

- Missing required asset symbol 'a' parameter returns validation error
- Invalid asset symbol returns empty or error response
- Unsupported network/asset combination returns error
- Payment not processed results in 402 Payment Required
- Invalid interval or currency enum value returns 400 Bad Request
