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 serp-extract-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-2f4618d7 -d '<json body>'
```

Example prompt: Scan all the top DeFi pools for USDC and tell me which ones have the best risk-adjusted APY right now — include TVL depth and which chains they're on.

## When to prefer this

Use this endpoint when an agent needs live, cross-chain DeFi yield comparison for a specific asset — particularly when risk-adjusted APY and TVL depth matter, not just raw APY. Prefer this over generic price feeds when the goal is yield optimization or liquidity pool selection across multiple chains simultaneously.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama data temporarily unavailable causing stale or missing APY data
- Pools with very low TVL may be included but flagged as high-risk
- Network timeouts if upstream DeFiLlama API is slow
- Malformed asset string (e.g. empty string) triggers 400 validation error
