## 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-spent-volume-lifespan-10y-svl-more-10y-8b12f5da
```

Example prompt: Pull the Glassnode on-chain metric for Bitcoin spent volume lifespan greater than 10 years — give me the data in JSON format denominated in native BTC units.

## When to prefer this

Use this endpoint when you need to specifically track the movement of ancient Bitcoin (dormant >10 years), which is a strong signal for long-term holder behavior, potential market impact from old wallets waking up, or historical analysis of coin lifespan metrics. Prefer this over general transaction volume endpoints when the age-stratified spent volume dimension is critical to analysis.

## Known failure modes

- Missing required 'a' (asset) query parameter returns 400 error
- Unsupported asset symbol (non-BTC) returns validation error
- Payment not provided or insufficient USDC returns 402 Payment Required
- Invalid format or interval enum value returns 400
- Glassnode data unavailable for requested date range returns empty array or 404
