## 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 whale-momentum-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-1c1dda09
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC right now — I want to see the best APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum so I can find the best place to park my stablecoins.

## 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. It is especially useful for comparing yield opportunities across multiple chains (Base, Arbitrum, Solana, Ethereum) simultaneously and for identifying Pendle PT yield arbitrage. Prefer this over manual DeFiLlama browsing when an agent needs structured, programmatic yield data for decision-making.

## Known failure modes

- Missing or empty asset parameter returns validation error
- Unknown or unsupported asset symbol may return empty results or error
- DeFiLlama upstream outage may cause stale or unavailable data
- Payment failure (HTTP 402) if $0.01 USDC micropayment not completed
- Rate limiting if too many requests in a short window

## 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://whale-momentum.agentdiet.dev/v1/pendle-pt-yields)

## Output

Returns a structured object containing live APY rates, TVL depth figures, and risk-adjusted yield spreads for the queried asset across DeFi pools on Base, Arbitrum, Solana, and Ethereum, ranked so the agent can identify top yield opportunities.
