## 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-mean-transfer-volume-9b97cfaf
```

Example prompt: Pull the Glassnode mean transfer volume for BTC in USD over the last 24 hours and show me the latest data points.

## When to prefer this

Use this endpoint when you need the average (mean) value per individual on-chain transfer for a specific crypto asset. Prefer this over total transfer volume endpoints when you want per-transfer averages rather than aggregate sums, and over median endpoints when mean is the required statistic. Best for trend analysis of typical transfer sizes over time.

## Known failure modes

- Missing required 'a' (asset) query parameter returns an error
- Unsupported asset symbol returns a 4xx error
- Invalid interval or currency enum value returns a validation error
- Payment not fulfilled results in HTTP 402 response requiring USDC payment
- Rate limiting or quota exceeded may return 429
- Network not supported for a given metric returns an error
