## 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-output-lifespan-6m-12m-sol-6m-12m-2cfde51b
```

Example prompt: Pull the Glassnode spent output lifespan data for BTC showing how many outputs aged between 6 and 12 months were spent, in JSON format with 24h resolution.

## When to prefer this

Use this endpoint when you need to analyze Bitcoin UTXO age cohort behavior specifically for the 6-to-12-month holding band, which is often used to gauge medium-term holder conviction and distinguish between short-term speculation and longer-term holding patterns. Prefer this over generic transaction volume metrics when the age distribution of spent coins matters for market cycle analysis.

## Known failure modes

- Missing required 'a' parameter (asset) returns 400 error
- Unsupported asset symbol returns validation error
- Payment not included or invalid USDC payment returns 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Service unavailable returns 503
