## 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 synthora-defi-yield-scout-3de066ab -d '<json body>'
```

Example prompt: Find me the top 5 DeFi pools with the best APY for USDC on Arbitrum with at least $500K TVL — I want to see which protocols are offering the highest yields right now.

## When to prefer this

Use this endpoint when you need real-time DeFi yield comparisons across a broad universe of EVM-compatible chains and protocols. Prefer it over on-chain queries when breadth of coverage (6000+ pools) and cross-protocol comparison via DefiLlama aggregation is more valuable than raw on-chain precision.

## Known failure modes

- No pools found matching the specified asset or chain filter — returns empty result set
- Invalid or unrecognized asset name returns no matches
- DefiLlama data source unavailable or stale — may return outdated APY figures
- Overly restrictive TVL minimum filters out all matching pools
- Ambiguous query keyword matches unintended protocols or assets

## How this service works

Find the best APY across 6000+ DeFi pools on all EVM chains via DefiLlama. Filter by asset, chain, minimum TVL, and protocol. Returns top pools sorted by APY with TVL and protocol metadata.

## Output

Returns a ranked list of DeFi pools sorted by APY, each with TVL, protocol name, chain, pool identifier, and yield metadata sourced from DefiLlama across 6000+ pools.
