## 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-supply-last-active-2y-3y-metric-a1aad76b
```

Example prompt: Pull the Glassnode 'supply last active 2y-3y' metric for BTC in native units as JSON so I can see how much circulating supply hasn't moved for 2 to 3 years.

## When to prefer this

Use this endpoint when you need granular on-chain coin age band data specifically for the 2-to-3-year dormancy window, sourced from Glassnode's institutional-grade blockchain analytics. Prefer this over generic market data APIs when analyzing long-term holder conviction, HODL waves, or supply maturation trends for BTC, ETH, or other supported assets.

## Known failure modes

- Missing required 'a' (asset) query parameter returns a 400 error
- Invalid asset symbol (e.g. unsupported ticker) returns an error or empty dataset
- Invalid enum value for 'c', 'f', 'i', or 'network' returns a 400 validation error
- Payment not included or insufficient USDC results in 402 Payment Required
- Network not supported for the selected metric returns an empty or error response
- Rate limiting may produce 429 errors for excessive requests
