## 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-404b5bfa -d '<json body>'
```

Example prompt: Can you scan all the live DeFi pools for USDC and tell me which ones have the best risk-adjusted APY right now across Base, Arbitrum, Solana, and Ethereum?

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data aggregated from DeFiLlama with risk-adjusted scoring — particularly when comparing yield opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing when you need machine-readable, ranked output for agent-driven capital allocation decisions. Best suited for yield arbitrage scanning, treasury management automation, and DeFi portfolio optimization tasks.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result set
- DeFiLlama data unavailability may result in stale or incomplete pool data
- Very low-liquidity or newly launched pools may not appear in results
- Payment failure via x402 returns HTTP 402 and blocks execution
- Malformed request body (missing required 'asset' field) returns a 400 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/defi-yield)

## Output

Returns a ranked list of DeFi liquidity pools for the specified asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, chain of deployment (Base, Arbitrum, Solana, or Ethereum), and risk-adjusted yield spreads to facilitate arbitrage decisions.
