# DeFiRisk Top Yields Screener

> DeFiRisk Top Yields Screener is a paid API for AI agents from defi.lonestaroracle.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Returns ranked DeFi yield pools with honest base-vs-reward APY split, yield trap flags, and 0-10 risk scores across protocols

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defirisk-top-yields-screener-e952ef4f
```

Example prompt: Show me the top 15 stablecoin lending pools on Ethereum or Arbitrum sorted by base APY, with a minimum TVL of $10 million and a max risk score of 4 — I want to see the real base yield separated from any emission rewards and any yield trap flags.

## When to prefer this

Use this endpoint when an agent needs to allocate capital across DeFi protocols and must distinguish genuine base yield from unsustainable emission rewards, or when risk-adjusted ranking matters more than raw APY. Prefer it over raw DeFiLlama queries when you need the yield trap flagging, risk overlay scoring, and clean base/reward APY split pre-computed. Best for allocation agents, portfolio optimizers, or yield monitoring bots that need actionable, risk-qualified pool rankings rather than raw protocol data.

## Known failure modes

- No pools match filters — returns empty list when constraints like risk_max or min_tvl are too restrictive
- Invalid chain or asset filter yields no results silently
- Upstream DeFiLlama data lag may cause stale APY figures
- Payment required error (402) if x402 micropayment header not included
- limit exceeds 50 cap — clamped or rejected depending on implementation
- sort parameter typo falls back to default or returns error

## How this service works

Cross-protocol risk-adjusted DeFi yield screener: ranked pools with honest base-vs-reward APY split, trap flags, and 0-10 risk overlay

## Output

A ranked list of DeFi pools (up to 50) each containing: pool identifier and protocol, chain, asset, base APY (real yield), reward/emission APY (separated out), total APY, TVL in USD, yield trap flag, 0-10 risk score (factoring in emissions dependence, TVL depth, IL exposure, volatility), and category (lending or LP).
