## 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 api-carbon-cashmere-de-c6274715
```

Example prompt: Show me the top 10 DeFi pools with at least 5% APY on Ethereum right now — I want to see both the APY and TVL for each pool so I can decide where to allocate yield.

## When to prefer this

Use this endpoint when you need real-time DeFi yield data across a broad set of protocols and chains in a single call. Ideal for yield farming optimization, portfolio allocation decisions, or comparing APY/TVL across Aave, Compound, Uniswap, Curve, Lido, Pendle on Ethereum, Arbitrum, Base, and Polygon. Prefer over manual protocol-by-protocol queries when breadth (200 pools, 85 protocols) matters.

## Known failure modes

- Invalid chain name returns empty results or 400 error
- min_apy filter too high returns empty pool list
- Rate limiting or payment failure returns 402 or 429
- Protocol name typo causes no matching results
- Stale data if upstream protocol APIs are delayed
