## 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 alpha-stream-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-038667bb -d '<json body>'
```

Example prompt: Scan DeFiLlama and find me the top risk-adjusted yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — I want to know which pool has the best APY and TVL depth.

## When to prefer this

Choose this endpoint when you need real-time, multi-chain DeFi yield comparison for a specific asset — especially when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield queries when an agent needs to programmatically rank pools for yield optimization or arbitrage detection.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty pool list
- DeFiLlama data unavailable or stale due to upstream API downtime
- Asset has no qualifying liquidity pools across scanned chains
- Payment failure via x402 returns HTTP 402 and no data
- Malformed request body missing required 'asset' field returns validation error

## 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://alpha-stream.agentdiet.dev/v1/pendle-pt-yields)

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including live APYs from DeFiLlama, TVL depth per pool, chain attribution (Base, Arbitrum, Solana, Ethereum), and risk-adjusted yield spread comparisons to help identify optimal yield opportunities.
