# x402 DeFi Signals — Yield Opportunities

> x402 DeFi Signals — Yield Opportunities is a paid API for AI agents from x402-defi-signals.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns top DeFi yield opportunities per chain from DefiLlama, filtered by TVL and cleaned of unsustainable outlier APYs, sorted by APY

## Facts

- Endpoint: GET https://x402-defi-signals.onrender.com/defi/yields
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 x402-defi-signals-yield-opportunities-d10b5cd9
```

Example prompt: Show me the top DeFi yield opportunities on Arbitrum right now — only pools with at least $5 million TVL and cap outliers at 200% APY so I can see realistic, sustainable yields.

## When to prefer this

Use this endpoint when an AI agent needs clean, actionable DeFi yield data without having to manually scrape or filter DefiLlama. Prefer it over raw DefiLlama API calls when you need outlier-cleaned APY data (meme/unsustainable pools removed) already sorted and ready for yield-hunting decisions. Ideal for agents comparing yield opportunities across chains or recommending DeFi allocations.

## Known failure modes

- Unknown or misspelled chain name returns empty results or error
- DefiLlama upstream data unavailable causes 502/503
- Very high min_tvl_usd filter returns empty list
- max_apy_pct set too low filters out all pools
- Payment not processed results in 402 response

## How this service works

Top DeFi yield opportunities per chain from DefiLlama — TVL-filtered, outlier-cleaned (unsustainable meme-pool APYs removed), sorted by APY. Fields: project, symbol, apy_pct, apy_base_pct, tvl_usd, stable. Ideal for yield-hunting agents.

## Output

A ranked list of DeFi liquidity pools for the requested chain, each entry containing the project name, pool symbol, current APY percentage, base APY percentage, TVL in USD, and a flag indicating whether the pool is stablecoin-based. Outlier pools with unsustainably high APYs are pre-filtered out. Results are sorted descending by APY.
