## 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

Example prompt: Pull the latest derivatives analytics for SOL — I want to know the open interest regime, current funding rate and its 30-day z-score, and whether the market is showing a long or short bias right now.

## When to prefer this

Use this endpoint when you need structured, pre-computed derivatives signals for SOL specifically — open interest regime classification, funding z-scores, and basis analytics — rather than raw price feeds or spot data. Ideal for agents building trading dashboards, risk monitors, or regime-aware strategies that need derivatives context beyond simple price.
