## 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-historical-price-funding-open-interest-snapshots-api-39a1f3cd
```

Example prompt: Pull the historical price, funding rate, and open interest snapshots for BTC on Hyperliquid — I need this time-series data for backtesting since Hyperliquid doesn't serve it retroactively.

## When to prefer this

Use this endpoint when you need retroactive historical time-series data (price, funding rate, open interest) for a specific Hyperliquid perpetuals market that the exchange itself does not expose via its own API. Ideal for backtesting quantitative strategies, analyzing past funding regimes, or reconstructing open interest trends over time for a single symbol.

## Known failure modes

- Symbol not found or unsupported — returns error if the market symbol doesn't exist on Hyperliquid
- No historical data available for a very new or recently listed market
- Rate limiting or payment failure if the x402 payment of $0.05 USDC is not processed correctly
- Malformed symbol parameter causes a bad request response

## How this service works

Backtesting raw material for one market: price, funding and open-interest snapshots we recorded over time, as a series the exchange does not serve retroactively

## Output

A time-series array of snapshots for the requested symbol, each containing a recorded timestamp alongside mark price, funding rate, and open interest values — historical data recorded by whaletape.xyz that is not available retroactively from the Hyperliquid exchange directly.
