## 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 statepulse-finance-halts-live-trading-halt-lookup-aac99541 -d '<json body>'
```

Example prompt: Can you check if ticker XYZ is currently under a trading halt and tell me the halt time and reason code?

## When to prefer this

Use this endpoint when you need real-time trading halt status and reason codes for individual equities — particularly useful during volatile market sessions or when monitoring for regulatory halts like LUDP, T1, T2. Prefer this over general market data APIs when halt-specific regulatory codes and timing precision are required.

## Known failure modes

- Ticker not found or unsupported: supported field returns false
- Network or worker timeout causing no response
- Invalid ticker format causing a 4xx error
- No active halts found: halts array is empty
- Stale data if live feed is delayed

## How this service works

Parses the Nasdaq Trader RSS feed for active or recent stock trading halts.

## Output

A JSON object containing an array of active halt records for the queried ticker, each with ticker symbol, halt time, and regulatory reason code (e.g. LUDP), plus a 'supported' boolean and a confidence level string (e.g. 'high').
