## 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-node-funding-payments-911c87e2
```

Example prompt: What's the current hourly funding rate and total open interest for BTC perps on Hyperliquid right now — and what does that annualize to in APR?

## When to prefer this

Use this endpoint when you need low-latency, pay-per-call Hyperliquid funding rate and open interest data without managing API keys or subscriptions. Ideal for AI trading agents making infrequent spot checks on funding costs across BTC, ETH, or SOL perps. Prefer this over broader multi-venue funding endpoints when you only need Hyperliquid node-level data at minimal cost per call.

## Known failure modes

- Invalid or unsupported coin symbol returns validation error
- Payment failure (insufficient USDC or x402 protocol issue) blocks the call
- Hyperliquid API upstream outage causes stale or missing data
- Network timeout from the Cloudflare Worker proxy
- Only BTC, ETH, SOL are supported — requests for other coins will fail

## 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

Returns a JSON object with the coin's mark price, oracle price, open interest (in contracts and USD), hourly funding rate, annualized funding APR percentage, venue name (hyperliquid), data sources, and an updated_at timestamp.
