## 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 polymarket-odds-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-bf422ad1
```

Example prompt: Scan DeFi pools for USDC and show me the top risk-adjusted yield opportunities right now, including APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum.

## When to prefer this

Use this endpoint when you need a real-time, multi-chain comparison of DeFi yield opportunities for a specific asset, especially when optimizing for risk-adjusted returns rather than raw APY. Prefer this over single-protocol dashboards when you need cross-chain aggregation across Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty results
- DeFiLlama data unavailable or stale due to upstream outage
- Pools with very low TVL may appear but carry high impermanent loss risk not fully captured
- Payment not processed (HTTP 402) if x402 micropayment fails

## How this service works

Scans live DeFiLlama APYs, TVL depth, and risk-adjusted yield spreads across Base, Arbitrum, Solana, and Ethereum pools. (Live x402 v2, IETF MPP & MCP endpoint at https://polymarket-odds.agentdiet.dev/v1/yield-aggregator)

## Output

Returns a structured list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth, risk-adjusted yield spreads, and rankings across Base, Arbitrum, Solana, and Ethereum pools.
