Example prompt: Can you pull the top 20 tokens ranked by market cap right now, including their price, trading volume, and supply metrics — and give me the AI analysis summary on each?

## When to prefer this

Choose this endpoint when you need a ranked market cap view of top tokens with both raw metrics (price, volume, supply) and AI-generated interpretation in a single call. Prefer it over raw Bitquery queries when you want actionable AI analysis layered on top of market cap data, or when building dashboards that need both quantitative rankings and qualitative insights simultaneously.

## Known failure modes

- Invalid or missing request parameters returns 400 error
- Payment not received or insufficient USDC returns 402 payment required
- Upstream Bitquery API unavailable returns 503 or timeout
- Rate limiting if too many requests in a short window
- Empty result set if no tokens match filter criteria
