# SiteCheck DeFi Yields

> SiteCheck DeFi Yields is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Returns top DeFi yield pools filtered by chain, protocol, token symbol, and minimum TVL, sourced from DefiLlama

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 sitecheck-defi-yields-1c0ce19c
```

Example prompt: Can you find me the top 10 DeFi yield pools on Base with at least $2M TVL — I'm especially interested in USDC pools and want to see the base APY and reward APY separately?

## When to prefer this

Use this endpoint when you need a filtered, ranked view of DeFi yield pools with structured APY breakdowns (base vs reward) sourced from DefiLlama. Prefer this over raw DefiLlama API calls when operating in a pay-per-call agent context and you need quick access to pre-filtered, cached pool data without managing API keys. Best for agents comparing yield opportunities, recommending liquidity positions, or monitoring DeFi rates across chains.

## Known failure modes

- Invalid chain name returns empty results or error
- Limit out of range (outside 1-50) may be ignored or cause error
- Very restrictive filter combinations (symbol + chain + project) may return zero pools
- Cached data may be up to 30 minutes stale
- Pools below $1M TVL are always excluded regardless of minTvlUsd parameter

## How this service works

DeFi yield pools from DefiLlama with at least $1M TVL, sorted by APY and filtered by chain, project or symbol (max 50). APY is DefiLlama's estimate, split into base and reward; reward APYs are often temporary. Attribution: Data: DefiLlama. Information only, not financial advice.

## Output

Returns a JSON object containing a list of yield pools each with pool ID, chain, symbol, project/protocol name, total APY, base APY, reward APY, TVL in USD, and stablecoin flag. Also includes metadata: total count, data source attribution (DefiLlama), cache timestamp, applied TVL floor, and a disclaimer that this is informational only.
