## 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-current-funding-rate-x402-7f6a70cc
```

Example prompt: What's the current funding rate and open interest for BTC perpetuals on Hyperliquid — give me the hourly rate, annualized APR, and mark vs oracle price?

## When to prefer this

Use this endpoint when you need real-time Hyperliquid-specific perpetual funding rate data (hourly rate, APR, open interest, mark/oracle prices) for BTC, ETH, or SOL without managing API keys. Ideal for AI trading agents that need pay-per-call microdata via x402 USDC payments on Base. Prefer this over general market data APIs when Hyperliquid funding rates specifically are needed for arbitrage analysis, cash-and-carry setups, or perp bot state refreshes.

## Known failure modes

- Unsupported coin symbol returns an error or empty result (only BTC, ETH, SOL are valid enum values)
- Payment failure via x402 if USDC balance on Base is insufficient
- Stale data if Hyperliquid API is temporarily unavailable (updated_at timestamp will be old)
- Network timeout from the Cloudflare Worker if upstream Hyperliquid API is slow
- Missing coin parameter defaults to BTC — may return unexpected asset if caller forgets to specify

## 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, for the requested coin: mark price, oracle price, open interest (in contracts and USD), hourly funding rate, annualized funding rate (APR %), the venue name ('hyperliquid'), upstream source URLs, and an ISO 8601 timestamp of when the data was last updated.
