## 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 scrapling-x402-defi-yield-lookup-19843837
```

Example prompt: What's the current APY for USDC on Base across DeFi protocols, and what's the risk-adjusted yield?

## When to prefer this

Use this endpoint when you need current DeFi yield (APY) data for a specific token on a specific blockchain, especially when risk-adjusted returns are important. Prefer this over general web search when you need structured, machine-readable yield data with risk scores attached.

## Known failure modes

- Unsupported chain or token returns empty results array
- Missing required query parameters returns validation error
- Payment not settled results in HTTP 402 response requiring x402 payment
- Rate limiting or service downtime returns 5xx error

## How this service works

Best USDC (or any token) yield on Base or any chain: top 10 pools ranked by risk-adjusted APY, each with APY, TVL and a 0-100 risk score. Example: chain=Base&token=USDC, token=ETH, chain=Arbitrum. Refreshed about every 30 min

## Output

Returns a list of DeFi yield results for the queried chain and token, each containing: chain name, token symbol, APY percentage, project name (e.g. aave-v3), risk score (0-100), and risk-adjusted APY percentage.
