## 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-90d-age-adjusted-coin-days-destroyed-cdd-90-5c1e5a6d
```

Example prompt: Can you pull the latest 90-day age-adjusted Coin Days Destroyed (CDD-90) data for BTC from Glassnode in JSON format at daily resolution?

## When to prefer this

Use this endpoint when you need age-adjusted, long-term normalized Bitcoin spending behavior analysis rather than raw CDD. Prefer CDD-90 over raw CDD when comparing activity across different time periods in Bitcoin's history, since the normalization corrects for the naturally growing coin-age baseline. Ideal for on-chain analysts tracking macro holder behavior shifts.

## Known failure modes

- Missing required 'a' query parameter returns a 400 error
- Unsupported asset symbol returns an error (only BTC currently supported)
- Payment not completed or invalid x402 payment header returns 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Glassnode data unavailable or server error returns 500

## How this service works

90D Coin Days Destroyed (CDD-90) — 90D Coin Days Destroyed (CDD-90) is the 90-day rolling sum of Coin Days Destroyed (CDD), age-adjusted by normalizing for time to account for the increasing destructible-coin-age baseline as the network ages. Data by Glassnode.

## Output

Returns a JSON array of time-series data points, each containing a Unix timestamp (t) and the corresponding age-adjusted 90-day CDD value (v), representing normalized coin-age destruction activity over rolling 90-day windows.
