## 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-median-transfer-volume-907c4352
```

Example prompt: Pull the Glassnode median transfer volume for BTC in USD at daily (24h) resolution — I want to see what a typical on-chain Bitcoin transfer looks like right now.

## When to prefer this

Use this endpoint when you need the median (not mean or total) value of on-chain transfers for a specific cryptocurrency, which filters out outlier whale transactions and gives a clearer picture of typical user behavior. Prefer this over total transfer volume endpoints when you want to understand the 'typical' transaction size rather than aggregate flow.

## Known failure modes

- Missing required asset symbol 'a' parameter returns validation error
- Unsupported asset symbol returns error or empty data
- Invalid interval or currency enum value returns 400
- Network parameter incompatible with selected asset returns error
- Payment of $0.05 USDC not fulfilled triggers 402 response
- Rate limiting or quota exceeded returns 429

## How this service works

Median Transfer Volume — The median value of a transfer. Data by Glassnode.

## Output

An array of timestamped data points where each object contains a Unix timestamp (t) and the median transfer volume value (v) in the requested currency and resolution for the specified asset and network.
