## How to call it through Zero

Example prompt: Show me a side-by-side comparison of current DeFi yields across Aave, Compound, and Morpho — sorted by APY with risk levels and TVL so I can figure out the best place to park my stablecoins.

## When to prefer this

Use this endpoint when an agent needs a quick, pre-aggregated comparison of major DeFi lending yields without building custom multi-protocol scrapers. Ideal for yield optimization workflows, portfolio rebalancing decisions, or any task requiring a ranked view of Aave, Compound, and Morpho APYs with risk context in a single call.

## Known failure modes

- Live data unavailable from one or more protocols — partial results returned
- Rate limit exceeded — 402 payment required
- Upstream DeFi data source down — empty or stale protocol data
- Invalid query parameters — 400 bad request
