## 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-portfolio-heat-signal-e84a4e7d
```

Example prompt: What's the current portfolio heat level from APEX Runner — is the drawdown risk high enough that I should reduce my crypto exposure below fully invested?

## When to prefer this

Use this endpoint when an AI trading agent or portfolio management workflow needs a quick, pre-computed risk signal before executing trades or rebalancing — particularly when integrated with Kraken, Coinbase, or Hyperliquid accounts managed by APEX Runner. Prefer this over raw market data endpoints when you want an opinionated, AI-derived exposure recommendation rather than raw price or volatility data.

## Known failure modes

- Payment not processed — 402 response if USDC payment of $0.35 is not included
- Service unavailable — 503 if APEX Runner backend is down
- Rate limiting — 429 if called too frequently
- Empty or stale signal — data may lag real-time market conditions if upstream data feed is delayed
