## 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 proxy-suverse-io-8f7b96d3 -d '<json body>'
```

Example prompt: What's the current open interest for BTCUSDT perp on Binance, and has it been building or unwinding over the last 24 hours? I want to see the 5-minute OI history and the change percentage so I can gauge leverage pressure.

## When to prefer this

Use this endpoint when you need real-time open interest data for Binance perpetual contracts specifically, including both the current snapshot and 24-hour granular history at 5-minute resolution. Prefer this over generic market data APIs when your use case involves detecting leverage buildups, identifying potential short/long squeeze setups, or monitoring funding pressure precursors where OI trend matters as much as current level.

## Known failure modes

- Invalid or unsupported contract symbol returns an error
- Symbol not a perpetual contract (e.g. spot or quarterly) may return no data
- Binance API rate limits or downtime cause upstream failures
- Malformed POST body returns a 400 validation error
- Payment not included or insufficient USDC returns a 402 error
