## 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 vealth-regen-class-momentum-scorer-6e4bf7bc -d '<json body>'
```

Example prompt: What's the current momentum score for carbon credit class C01 — is it trending up, and how does the retirement velocity and liquidity look right now?

## When to prefer this

Use this endpoint when you need a composite, pre-scored momentum signal for a specific regenerative carbon credit class that combines both liquidity depth and retirement velocity into a single labeled score. Prefer it over raw market data feeds when you want an opinionated, weighted signal ready for trading or portfolio decisions without building your own scorer.

## Known failure modes

- Unknown or invalid class_id returns an error or empty result
- Class with no recent trading activity may return null or zero liquidity values
- Network timeout if upstream carbon market data feed is unavailable
- Stale data if retirements registry is delayed — fetched_at timestamp will indicate freshness

## Output

A JSON object containing the class ID, a momentum label (e.g. 'strong_up') and numeric score, liquidity details (active order count, total quantity, floor price in USD), retirement statistics for the last 24 hours (count and total tonnes), a retirement velocity z-score, the prior 6-day daily average, component weights used in scoring, and metadata including fetch timestamp and spec/scorer versions.
