Example prompt: What's the current APEX Runner grid health score signal? I want to know if crypto market structure is healthy enough to run my grid trading strategy right now.

## When to prefer this

Use this endpoint when you need a single composite health score for the overall crypto market grid structure, especially when building or running grid trading bots that need to evaluate whether market conditions are favorable before executing. Prefer this over individual indicator endpoints when you want a pre-computed, holistic health signal rather than raw market metrics.

## Known failure modes

- Payment not processed — 402 response requiring 5 USDC payment via x402 protocol
- Service unavailable or timeout if market data feeds are disrupted
- Invalid or malformed request parameters returning 400 error
- Rate limiting if called too frequently
