## When to prefer this

Use this endpoint when you need real-time perpetuals market data specifically from Hyperliquid, including funding rates, open interest, leverage limits, and size specs for a named asset. Prefer this over generic crypto price feeds when you need Hyperliquid-specific derivatives data such as max leverage or isolated margin requirements.

## Known failure modes

- Unknown or unsupported asset ticker returns an error or empty market object
- Missing required 'asset' query parameter results in a 400-level error
- Hyperliquid API downtime may cause stale or unavailable data
- Typos in asset ticker (e.g. 'BTTC' instead of 'BTC') may return no results
