## 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-coin-blocks-destroyed-metric-633a0c46
```

Example prompt: Pull the latest Coin Blocks Destroyed data for Bitcoin from Glassnode — I want the 24-hour interval figures in native units as JSON so I can see how much economic weight is being moved on-chain.

## When to prefer this

Use this endpoint when you need to analyze Bitcoin's economic activity by weighting coins both by quantity and by time since last spent — particularly useful for assessing dormancy, long-term holder behavior, and on-chain economic weight. Prefer over simple transaction volume or coin days destroyed when you need the raw block-weighted metric rather than supply-adjusted variants.

## Known failure modes

- Missing required asset parameter 'a' returns a 400 validation error
- Unsupported asset symbol (non-BTC) returns an enum validation error
- Payment not processed or expired x402 token returns a 402 Payment Required error
- Invalid format or interval enum value returns a 400 error
- Network timeout or upstream Glassnode data outage returns a 503 or 504 error

## How this service works

Coin Blocks Destroyed — Coin Blocks Destroyed for any given transaction is calculated by taking the number of coins in a transaction and multiplying it by the number of blocks it has been since those coins were last spent. Data by Glassnode.

## Output

Returns a time series array of objects each containing a Unix timestamp (t) and the Coin Blocks Destroyed value (v) for that period, reflecting Bitcoin's economic dormancy and spending weight over the requested interval.
