## 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-1h-svl-1h-6593f2be
```

Example prompt: Can you pull the Glassnode spent volume lifespan under 1 hour metric for BTC in USD at daily resolution and give me the latest data points in JSON?

## When to prefer this

Use this endpoint when you need time-series data specifically about Bitcoin coins that were spent within one hour of being received, which is a key on-chain indicator of short-term speculative activity or hot wallet behavior. Prefer this over general volume metrics when distinguishing freshly moved coins from older held coins matters for your analysis. Ideal for on-chain analysts building dashboards, trading signals, or market research workflows requiring Glassnode's SVL_1H indicator.

## Known failure modes

- Missing required 'a' (asset) parameter returns a 400 or 422 validation error
- Invalid asset symbol (not 'BTC') returns an error as only BTC is currently supported
- Invalid currency or format enum value returns a validation error
- Payment not provided or insufficient USDC balance results in 402 Payment Required
- Rate limiting or quota exceeded returns a 429 Too Many Requests
- Glassnode data unavailable for the requested interval returns empty or partial data
