## 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 hl-tape-244dcf6d
```

Example prompt: Pull the live Hyperliquid tape right now and tell me whether BTC or ETH looks better to trade based on the current market decision.

## When to prefer this

Choose this endpoint when you need a single, already-computed BTC-vs-ETH trading decision rather than raw price or funding data you'd have to interpret yourself. It is ideal for agents that need a quick actionable signal without doing their own cross-asset analysis. If you need raw mark prices, open interest, or funding rates individually, use the sibling HL Mark, HL Open Interest, or HL Funding endpoints instead.

## Known failure modes

- Hyperliquid API unreachable — upstream data unavailable, may return 502 or empty response
- Worker timeout if Hyperliquid data fetch is slow
- Stale or null decision if underlying market feed has a gap
- x402 payment failure if USDC payment header is missing or insufficient

## How this service works

Live Hyperliquid BTC-ETH decision. Recomputed every request. No parameters.

## Output

A freshly computed decision object indicating whether BTC or ETH is currently preferred based on Hyperliquid market conditions, likely including a recommended action, the basis for the decision, and supporting market metrics recomputed at request time.
