## 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-change-adjusted-e6c388fa
```

Example prompt: Pull the Glassnode change-adjusted mean Bitcoin transfer volume at daily resolution, denominated in USD, and give me the results as JSON.

## When to prefer this

Use this endpoint when you need Bitcoin on-chain transfer volume data that strips out change outputs to more accurately represent economic transfer activity, rather than raw transfer volume which inflates figures due to UTXO change. Prefer this over raw transfer volume metrics when analyzing true economic throughput on the Bitcoin network.

## Known failure modes

- Missing required 'a' (asset) query parameter returns a 400 error
- Unsupported asset symbol (non-BTC) returns validation error since only BTC is accepted
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Invalid interval or currency enum value returns a 400 bad request
- Network or upstream Glassnode data unavailability returns a 5xx error

## How this service works

Mean Transfer Volume (Change-Adjusted) — The mean value of a transfer, adjusted by change volume. Data by Glassnode.

## Output

An array of time-series data points, each containing a Unix timestamp (t) and the mean change-adjusted transfer volume value (v) for the specified asset, interval, and currency denomination.
