## 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 crypto-microdata-global-crypto-market-losers-x402-3232855e
```

Example prompt: Which crypto assets are down the most in the last 24 hours on Hyperliquid? Show me the top 10 losers with at least $1M in volume, including their funding rates and open interest.

## When to prefer this

Choose this endpoint when you need a ranked list of the worst-performing crypto assets by 24h price change from Hyperliquid perpetuals, with built-in liquidity filtering and market breadth context. Prefer it over generic market data APIs when you need funding rates, open interest, and leverage data alongside price performance in a single pay-per-call micro-payment call with no API key setup. Ideal for trading agents scanning for short opportunities or monitoring market-wide sentiment.

## Known failure modes

- Payment not received or x402 handshake fails — returns 402 Payment Required
- Hyperliquid upstream API unavailable — stale or empty data returned
- Invalid query parameter types (e.g. limit > 25 or non-integer) — 400 Bad Request
- min_volume_usd set too high — top_losers array may be empty if no coins meet liquidity filter
- Network timeout from upstream data source — partial or no response
