## How to call it through Zero

```sh
zero fetch --capability hyperextend-outcome-context-latest-759fc1f0
```

Example prompt: What's the latest market context for Hyperliquid outcome coin #1000 — give me the current mid price, mark price, circulating supply, and today's trading volume?

## When to prefer this

Use this endpoint when you need the single most recent snapshot of price, volume, and supply data for a specific HIP-4 outcome-side coin on Hyperliquid, rather than a historical window query. Prefer this over the windowed endpoint when you only need the latest state without specifying a time range.

## Known failure modes

- Invalid or malformed coin identifier returns 400 or empty response
- Coin not found / not a valid HIP-4 outcome coin returns 404
- Payment not completed (x402 protocol failure) returns 402
- Rate limiting or quota exceeded returns 429
- Stale data if the market has low activity or no recent trades

## How this service works

## Output

A JSON object containing the outcome coin identifier, mid price, mark price, circulating supply, day notional volume, day base volume, previous day price, and timestamps (minute and sample) for the most recent snapshot of the specified HIP-4 outcome-side market.
