## How to call it through Zero

```sh
zero fetch --capability blockrun-yield-pool-ranking-f00ecaef
```

Example prompt: What are the top-ranked on-chain yield opportunities right now — show me the best lending pools, LP positions, and staking options ranked by APY across protocols.

## When to prefer this

Use this endpoint when you need a comparative, ranked view of yield opportunities across multiple DeFi categories (lending, LP, staking) in a single call, rather than querying individual protocols separately. Ideal for agents helping users optimize yield allocation or discover new DeFi opportunities.

## Known failure modes

- No data available for requested filters — returns empty rankings
- Upstream on-chain data unavailable — 503 or timeout
- Payment not settled — 402 Payment Required
- Invalid query parameters — 400 Bad Request

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

A ranked list of on-chain yield pools spanning lending protocols, liquidity provision (LP) positions, and staking opportunities, ordered by yield metrics such as APY, along with protocol and pool identifiers.
