## 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 heurist-mesh-defillama-yield-pool-search-a0c981bd -d '<json body>'
```

Example prompt: Search DefiLlama for the best stablecoin yield pools on Ethereum and Arbitrum from Aave and Curve, and show me the APY and TVL trends for each.

## When to prefer this

Use this endpoint when you need to search and filter DeFi yield pools from the DefiLlama dataset by specific projects, chains, or token symbols, especially when you want compact APY and TVL trend summaries. Prefer this over generic DeFi APIs when you need cross-chain yield comparison with structured filtering. Best suited for agents doing yield optimization research, DeFi portfolio analysis, or stablecoin yield discovery.

## Known failure modes

- No pools found matching the specified filter combination
- Invalid project/chain/symbol name returns empty results
- Payment of $0.003 USDC not processed — request rejected
- Overly restrictive AND-combined filters yield zero results
- DefiLlama data temporarily unavailable causing stale or missing results

## How this service works

Search DefiLlama yield pools with optional filters for projects, chains, symbols, and stablecoin flag. Returns compact results with APY and TVL trend metrics. List filters (projects/chains/symbols) use OR matching, while different filter types are combined with AND.

## Output

Returns a compact list of matching yield pools from DefiLlama, each including the pool name, project, chain, symbol, current APY, and TVL trend metrics. Results are filtered by the specified criteria (projects, chains, symbols, stablecoin flag) with list-type filters using OR logic and cross-filter types combined with AND.
