## 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 coil-sector-scores-869bb46e
```

Example prompt: Which S&P 500 sectors are showing green signals right now, and what are their scores? I want to see the full sector rotation picture — XLK, XLF, XLE, XLV, the works.

## When to prefer this

Use this endpoint when you need a top-down view of sector rotation across all S&P 500 sectors at once, without scanning individual stocks. Ideal for identifying which sectors are leading or lagging, determining regime-aligned sector entries, and building macro-aware trading filters. Prefer over single-name endpoints when sector leadership context is needed before drilling into individual stocks.

## Known failure modes

- Market closed or outside hours — data may be stale or unavailable
- Rate limiting if called excessively — 402 or 429 response
- Upstream data feed delay — scores may lag by more than 5 minutes during high-volatility periods
- Malformed response if the scoring engine is restarting

## How this service works

Sector rotation scores — which sectors are strong right now? One read returns every S&P 500 sector ETF (XLK, XLF, XLV, XLE, XLI and the rest) scored 0-100 with percentile, green/yellow/red light and entry state, plus which sectors each book's regime currently calls green. Spot leadership rotation top-down without scanning 500 single names. Refreshed ~5 min in market hours, timestamped. Research, not advice.

## Output

A list of all S&P 500 sector ETFs (XLK, XLF, XLV, XLE, XLI, etc.) each with a numeric score from 0-100, percentile rank, green/yellow/red signal light, entry state, and regime-based green designation. Data is refreshed approximately every 5 minutes during market hours and includes a timestamp.
