## 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 kronos-signals-multi-symbol-signal-scores-ranked-top-k-list-e61b4c2a
```

Example prompt: Pull the latest Kronos signal scores right now and show me the top-ranked symbols across crypto — I want to know which assets are scoring highest so I can decide where to focus.

## When to prefer this

Use this endpoint when you need a broad, ranked overview of signal strength across the entire supported symbol universe rather than a deep dive into a single asset. It is the ideal starting point for portfolio scanning or opportunity filtering before calling /kronos/risk or /kronos/forecast for individual follow-up analysis.

## Known failure modes

- Payment not included or invalid — 402 Payment Required with x402 challenge
- Symbol universe unavailable — partial or empty signals object returned
- Stale data — ts timestamp may lag if upstream data source is delayed
- Rate limit exceeded — 429 Too Many Requests
- Service unavailable — 503 if Kronos backend is down

## How this service works

Returns latest per-symbol signal scores and a ranked top_k list across crypto and supported stock symbols — pair with /kronos/risk and /kronos/forecast for full decision context.

## Output

A JSON object containing a timestamp (ts), a signals map with per-symbol scores, and a top_k array of symbols ranked by signal strength from highest to lowest.
