## 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 market2000-xyz-sector-momentum-fba00c98
```

Example prompt: Show me which stock market sectors have the strongest ETF momentum right now using a 60-day lookback — rank all 11 GICS sectors hottest first and include the top leaders in each.

## When to prefer this

Use this endpoint when you need a quick, pre-computed cross-sector momentum ranking with named leaders rather than building your own ETF return calculations. Ideal for sector rotation strategies, macro overlay models, or any workflow that needs to know which parts of the market are trending strongest at a glance. Prefer this over individual stock screeners when the goal is top-down sector allocation rather than single-stock selection.

## Known failure modes

- lookback value outside 20–250 range returns validation error
- network timeout if underlying ETF data feed is slow
- stale data if market data pipeline is delayed
- payment failure if USDC balance is insufficient for the $0.05 per call fee
- empty leaders array if ETF constituent data is unavailable for a sector
