## 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 hyperliquid-perpetuals-snapshot-x402-76aa6e9f
```

Example prompt: What are the current mark price, oracle price, open interest, and funding rate for BTC perpetuals on Hyperliquid right now?

## When to prefer this

Choose this endpoint when you need real-time Hyperliquid perpetuals data (funding rates, open interest, mark/oracle prices) for BTC, ETH, or SOL without setting up API keys — especially suited for autonomous AI trading agents that can pay $0.005 USDC per call via the x402 micropayment protocol on Base. Prefer this over direct Hyperliquid API calls when operating in an agent environment with built-in x402 payment capability and no credential management.

## Known failure modes

- Invalid coin symbol returns an error (only BTC, ETH, SOL accepted)
- Payment failure via x402 if USDC balance on Base is insufficient
- Hyperliquid upstream API downtime causes stale or missing data
- Network timeout on the Workers edge if Hyperliquid source is slow
- Missing coin query param defaults to BTC (not an error, but may surprise callers expecting a different coin)

## How this service works

Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.

## Output

A JSON object containing the perpetuals snapshot for the requested coin, including mark_px (mark price), oracle_px (oracle price), open_interest (in coin units), open_interest_usd, funding_hourly (hourly funding rate), funding_apr_pct (annualized funding rate as a percentage), the venue name ('hyperliquid'), source URLs, and an updated_at timestamp.
