## 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 foundry-defi-yields-e168f673 -d '<json body>'
```

Example prompt: What are the highest-APY DeFi pools for USDC on Base right now, with at least $1M TVL?

## When to prefer this

Use this endpoint when you need real-time ranked DeFi yield data filtered by chain and token with a minimum TVL threshold of $1M, sourced from DefiLlama. Prefer it over manual DeFi dashboards when an agent needs structured, machine-readable pool data for decision-making or comparison. It is not suitable for portfolio management, trade execution, or historical yield charting.

## Known failure modes

- No pools found matching the given chain/token combination — empty pools array returned
- Unrecognized chain or token name may yield no results or unfiltered results
- DefiLlama upstream data may be stale or temporarily unavailable
- Input string not parseable as chain/token pair — may return unfiltered or error response
- Payment required (HTTP 402) if x402 payment is not properly included

## How this service works

DeFi yields: highest-APY pools with over $1M TVL, filtered by chain and token. Data only. Input: 'usdc base'.

## Output

A JSON array of DeFi liquidity pools matching the chain/token filter, each with APY (%), TVL in USD, pool symbol, project name, chain, and a stablecoin flag. Also includes the applied filters and data source attribution (DefiLlama). A disclaimer note is included that this is data only, not investment advice.
