## 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-3fdc35ce
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum right now — I want to see the best APYs and TVL depth so I can decide where to deploy capital.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset and want risk-adjusted rankings rather than raw APY alone. It is especially useful when scanning Morpho vaults and DeFiLlama-tracked pools across Base, Arbitrum, Solana, and Ethereum simultaneously, saving the need to aggregate multiple protocol dashboards manually.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unsupported or misspelled asset symbol may return empty results or an error
- DeFiLlama data unavailability could cause stale or missing APY data
- Payment failure via x402 may block the response
- Highly illiquid assets may return few or no matching pools

## 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/morpho-vault-apy)

## Output

Returns a structured list of DeFi liquidity pools for the requested asset, ranked by risk-adjusted yield. Data includes live APY rates sourced from DeFiLlama, TVL depth per pool, chain identifiers (Base, Arbitrum, Solana, Ethereum), and yield spread comparisons to help identify the most attractive deposit opportunities.
