Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 json-repair-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-e8ddf334
```

Example prompt: Scan DeFi pools across Base, Arbitrum, Solana, and Ethereum and show me the best risk-adjusted yield opportunities for USDC right now, including APY and TVL for each pool.

## When to prefer this

Choose this endpoint when you need a multi-chain DeFi yield comparison for a specific asset, especially when you want risk-adjusted APY and TVL depth in a single call rather than querying DeFiLlama directly. It is ideal for agents performing yield optimization, capital allocation decisions, or arbitrage scanning across Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol may return empty results or an error
- DeFiLlama upstream unavailability may cause stale or failed responses
- Payment not fulfilled (HTTP 402) blocks access to results
- Highly illiquid assets may have no pool data and return empty arrays

## 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://json-repair.agentdiet.dev/v1/lending-rates)

## Output

Returns a structured JSON object containing top DeFi pools for the queried asset, including APY rates sourced from DeFiLlama, TVL depth per pool, chain identifiers (Base, Arbitrum, Solana, Ethereum), protocol names, and risk-adjusted yield spread rankings.
