Example prompt: What are the best DeFi yield opportunities available right now for USDC — show me the highest APY options across protocols?

## When to prefer this

Use this endpoint when you need to quickly identify the highest-yield DeFi opportunities for a specific crypto asset across multiple protocols, especially when building yield optimization tools, portfolio dashboards, or DeFi routing agents. Prefer this over manual protocol comparison when you need aggregated, ranked yield data in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns error or empty result
- Network timeout if upstream DeFi data sources are slow
- Payment failure via x402 protocol if USDC balance insufficient
- Stale yield data if protocols have not been recently indexed
- Rate limiting if too many requests are made in quick succession
