# 2s.io DeFi Yield & Lending Rates

> 2s.io DeFi Yield & Lending Rates is a paid API for AI agents from 2s.io, paid per call via x402, $0.0036/call, status unknown (last checked 2026-09-13).

Returns DeFi pool yield and lending rates across protocols, ranked and filtered by APY, TVL, chain, project, and symbol with trend data.

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 2s-io-defi-yield-lending-rates-91ce1e73
```

Example prompt: Show me the top 20 USDC pools on Ethereum sorted by APY, only ones with at least $5 million TVL and a minimum 4% APY — I want to see base vs reward APY and the 7-day trend.

## When to prefer this

Use this endpoint when you need live DeFi yield or lending rate data across multiple protocols and chains — especially when filtering by specific assets (USDC, ETH), projects (Aave, Compound, Lido), or chains, and when APY trend history (1d/7d/30d) matters. Prefer over generic crypto price APIs when the goal is yield optimization or DeFi rate comparison.

## Known failure modes

- Invalid chain or project name returns empty result set or 400 error
- minApy or minTvlUsd filters too restrictive — returns empty array
- Limit exceeds maximum of 100 — validation error
- Upstream DefiLlama data temporarily unavailable — 502 or timeout
- Unknown symbol returns empty results with no error

## How this service works

DeFi yield & lending rates across protocols (via DefiLlama, free/keyless). Returns pools ranked by APY or TVL with base vs reward APY, TVL, 1d/7d/30d APY trend, stablecoin flag, and IL-risk. Filter by chain, project (aave, compound, lido…), symbol (USDC, ETH…), minApy, minTvlUsd. The yield/lending-rate layer beyond crypto.defi's TVL headline.

## Output

A ranked list of DeFi liquidity pools or lending markets, each with pool name, project, chain, token symbol, base APY, reward APY, total APY, TVL in USD, 1-day/7-day/30-day APY trends, stablecoin flag, and impermanent loss risk indicator.
