## 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 apex-runner-oi-divergence-signal-f80e6b6a
```

Example prompt: Check the current OI divergence signal for crypto — I want to know if price and open interest are moving in opposite directions right now, and whether it's a bearish or bullish divergence.

## When to prefer this

Use this endpoint when you need a fast, pre-computed OI divergence signal for crypto derivatives without building your own data pipeline. Ideal for trading agents that need to act on divergence-based signals in real-time at low per-call cost ($0.35 USDC). Prefer this over rolling your own OI analysis when latency and simplicity matter.

- Market data unavailable — upstream feed outage returns error
- Invalid or unsupported asset symbol returns 4xx
- Payment not confirmed via x402 returns 402 Payment Required
- Temporary rate limiting returns 429
