Example prompt: What's the current total supply of Bitcoin in loss right now — give me the Glassnode metric in native BTC units as JSON.

## When to prefer this

Use this endpoint when you need on-chain supply-in-loss data specifically for Bitcoin or Ethereum from Glassnode, particularly for market sentiment analysis, identifying capitulation events, or assessing the proportion of circulating supply held at unrealized losses. Prefer this over price-based metrics when you need holder-level cost-basis intelligence.

## Known failure modes

- Missing required asset symbol 'a' parameter returns a 400 error
- Unsupported asset symbol returns an error or empty dataset
- Payment not fulfilled triggers a 402 Payment Required response
- Invalid currency or format enum value returns a 400 validation error
- Rate limiting or quota exceeded returns a 429 error

## How this service works

Total Supply in Loss — The circulating supply in loss, i.e. the amount of coins whose price at the time they last moved was higher than the current price. Data by Glassnode.

## Output

Returns a time-series array of objects, each with a Unix timestamp (t) and the circulating supply currently held at a loss (v), expressed in either native coin units or USD depending on the 'c' parameter selected.
