## 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-signal-intelligence-5bc30eca
```

Example prompt: Pull the latest APEX Runner signal intelligence report — I want to see which signals are the top performers by revenue and unique agents, what the tier breakdown looks like, and any price recommendations the platform is suggesting.

## When to prefer this

Use this endpoint when you need a high-level meta-view of the entire APEX Runner signal ecosystem — not a specific trading signal itself, but analytics about the signals: which are popular, which are stagnant, what pricing the platform recommends, and how agent engagement looks. Prefer this over individual signal endpoints when doing catalog audits, marketplace health checks, or optimizing signal pricing strategy.

## Known failure modes

- No required parameters means the endpoint should always return data if the service is up; primary failure is service unavailability (503/504)
- Payment failure if x402 USDC payment of $3.50 is not properly submitted
- Stale data if the valid_for_seconds window has expired and cache has not refreshed
- Empty arrays for top_performers or zero_call_signals if catalog is new or unpopulated
