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-a6d7c05b
```

Example prompt: Scan DeFiLlama for the top risk-adjusted USDC yield pools right now across Base, Arbitrum, Solana, and Ethereum — show me APY, TVL, and which chains have the best spreads.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset with risk-adjusted scoring and TVL depth — especially when comparing multiple protocols across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield tools when an agent needs structured, scannable yield data in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causes stale or missing pool data
- Payment failure via x402 prevents response
- Rate limiting if too many calls in short succession
- Very new or illiquid assets may return no matching pools

## 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/yield-scanner)

## Output

Returns a structured object containing top DeFi liquidity pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth, chain names (Base, Arbitrum, Solana, Ethereum), protocol names, and risk-adjusted yield spread rankings to help identify optimal yield opportunities.
