## 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 mcp-security-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-9eb4a5fe
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — sorted by APY and TVL depth?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted rankings rather than raw APY alone. Ideal for agents comparing yield farming or liquidity pool opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over on-chain queries when you need aggregated, pre-ranked pool data without reading multiple protocol contracts directly.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol returns no pool results or an empty list
- DeFiLlama upstream API downtime may cause stale or unavailable data
- Payment failure (x402) results in 402 Payment Required response
- Rate limiting or quota exhaustion may return 429 errors

## 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://mcp-security.agentdiet.dev/v1/pendle-pt-yields)

## Output

Returns a structured list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL (total value locked) depth per pool, chain identifiers (Base, Arbitrum, Solana, Ethereum), and risk-adjusted yield spread rankings to help identify the best yield opportunities.
