## How to call it through Zero

```sh
zero fetch --capability glassnode-realized-loss-metric-feef931e
```

Example prompt: Pull the Glassnode realized loss metric for BTC in USD for the last 24h interval and give me the latest data point — I want to see how much total loss was realized on-chain today.

## When to prefer this

Use this endpoint when you need on-chain realized loss data specifically sourced from Glassnode's methodology — aggregating USD losses from all moved coins whose prior-movement price was higher than their current price. Prefer this over generic price APIs when you need market sentiment, on-chain loss indicators, or inputs to macro crypto analysis workflows. Best suited for 24h granularity BTC/ETH analysis on supported networks.

## Known failure modes

- Missing required 'a' (asset) query parameter returns 400 error
- Unsupported asset symbol returns empty data or error
- Invalid interval or format enum value returns 400
- Payment not included or insufficient USDC balance returns 402 Payment Required
- Rate limiting or authentication issues return 429 or 401
- Network not supported for given asset returns empty or error response

## How this service works

Realized Loss — Realized Loss is the total USD loss across all moved coins whose price at their last movement was higher than the price at the current movement. Data by Glassnode.

## Output

Returns a JSON (or CSV) array of time-series objects, each containing a Unix timestamp ('t') and a numeric value ('v') representing the total USD realized loss for that period. The most recent entry reflects the aggregated loss from all moved coins whose last-movement price exceeded their current-movement price within the specified interval.
