# YieldProbe DeFi Pool APY Intelligence

> YieldProbe DeFi Pool APY Intelligence is a paid API for AI agents from yieldprobe.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Returns top DeFi liquidity pools ranked by APY, enriched with 30-day mean, volatility (sigma), impermanent loss risk, and APY forecast, filterable by chain, project, stablecoin, and minimum TVL.

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 yieldprobe-defi-pool-apy-intelligence-f46993a3
```

Example prompt: Find me the top 20 DeFi yield pools on Arbitrum with at least $2M TVL — I want to see the 30-day average APY, volatility sigma, and impermanent loss risk so I can pick a stable, high-yield position.

## When to prefer this

Choose this endpoint when you need structured, enriched DeFi yield data with risk metrics (volatility, IL risk, APY forecast) beyond raw APY — especially when filtering by chain, protocol, or stablecoin status. Prefer over raw DefiLlama API calls when you need normalized, agent-ready data with sigma and forecasts included. Use when building yield optimization agents, DeFi portfolio tools, or automated liquidity allocation workflows.

## Known failure modes

- Invalid chain name returns empty results or validation error
- limit out of range (>100) may return error or be clamped
- minTvl or maxSigma provided as non-numeric string causes parse error
- Upstream DefiLlama data unavailability may return stale or partial data
- Payment failure via x402 results in 402 response before data is returned

## How this service works

Pay-per-call DeFi intelligence API for AI agents over x402: yields, APY anomalies, stablecoin pegs, token risk. USDC on Base.

## Output

A ranked list of DeFi liquidity pools, each containing the current APY, 30-day mean APY, APY volatility (sigma), impermanent loss risk score, APY forecast, TVL in USD, pool symbol, chain, and project — all normalized and cryptographically signed from DefiLlama source data.
