## 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-1w-1m-svl-7c8de5c2
```

Example prompt: Pull me the Glassnode spent volume lifespan 1w-1m metric for Bitcoin in USD — I want to see how much BTC that was last active between one week and one month ago has been moved recently.

## When to prefer this

Use this endpoint when you specifically need the spent volume segmented by coin lifespan in the 1-week to 1-month age band — a key indicator for distinguishing short-term holder behavior from longer-term coin movement. Prefer this over generic transaction volume metrics when analyzing whether recently-accumulated coins are being spent or held.

## Known failure modes

- Missing required 'a' parameter (asset) returns a 400 error
- Unsupported asset symbol causes validation failure
- Invalid currency or format enum values rejected by schema
- Payment not included or insufficient USDC triggers 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Glassnode data unavailable for requested date range returns empty array or 503
