# DeFi Yield Farming Screener

> DeFi Yield Farming Screener is a paid API for AI agents from www.x402financialdata.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns top DeFi yield-farming pools ranked by APY across ~15,800 tracked pools, with TVL, base/reward APY breakdown, 7-day APY change, impermanent-loss risk, and exposure type — filtered to pools with at least $1M TVL.

## 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 defi-yield-farming-screener-8ed503b4
```

Example prompt: Show me the top 20 stablecoin-only yield farming pools on Ethereum right now — I want APY, TVL, and impermanent-loss risk for each.

## When to prefer this

Use this endpoint when you need a broad, ranked snapshot of the best yield-farming opportunities across DeFi with real liquidity — especially when you need the base/reward APY split, impermanent-loss risk metadata, and 7-day trend all in one call. Prefer it over protocol-specific TVL endpoints (like the sibling DeFi Protocol TVL endpoint) when your goal is yield discovery across many pools rather than deep-diving into one protocol. Best for portfolio allocation research, weekly DeFi yield reports, or stablecoin yield optimization where liquidity quality (TVL floor) matters.

## Known failure modes

- Invalid chain name returns empty results or an error — must match DeFiLlama chain labels (e.g. 'Ethereum', not 'ETH')
- Limit exceeding 25 may be capped or return an error
- DeFiLlama data latency may cause slight staleness during high-volatility periods
- Pools with rapidly changing APY may show stale 7-day change figures if the upstream feed is delayed

## How this service works

Top DeFi yield-farming pools by APY across ~15,800 tracked pools, live from DeFiLlama: TVL, base/reward APY split, 7d APY change, impermanent-loss risk, and exposure type, with a $1M TVL floor to filter out illiquid noise. Optionally filter to one chain or stablecoin-only pools. Not ticker-specific. Supports optional limit (default 10, max 25). $0.01/call.

## Output

A ranked list of up to 25 DeFi yield-farming pools (default 10), each containing pool name, chain, TVL, total APY, base APY, reward APY, 7-day APY change, impermanent-loss risk level, and exposure type — sourced live from DeFiLlama with a $1M TVL floor to exclude illiquid pools.
