## 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-d2349961
```

Example prompt: Scan all DeFi pools for USDC and show me the top risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data with TVL depth and risk-adjustment signals for a specific asset, especially when comparing across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield queries when an agent needs structured, actionable yield arbitrage data programmatically.

## Known failure modes

- Missing or invalid asset symbol returns a 400 validation error
- Unknown asset ticker with no matching pools returns empty or null results
- DeFiLlama data unavailability causes stale or failed response
- Payment not processed (HTTP 402) blocks access to results
- Rate limiting or quota exhaustion returns 429 error

## How this service works
