## 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 raptor-base-yields-usdc-lending-apy-advisor-40ff8568
```

Example prompt: Check my Base wallet 0xAbc123... and tell me whether I should park my USDC in Aave V3 or Morpho Gauntlet on Base — show me the current APYs, how much I'd earn per year in USD, and whether it's even worth it after gas.

## When to prefer this

Use this endpoint when an agent needs a wallet-specific, size-aware yield recommendation on Base comparing exactly Aave V3 and Morpho Gauntlet USDC Prime — it accounts for gas economics and returns a concrete annual USD figure rather than just raw APY percentages. Prefer it over generic DeFi data APIs when the decision context is a specific wallet's balance on Base and the question is whether to act at all given transaction costs.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Wallet with zero USDC balance may return a skip recommendation with no meaningful yield data
- On-chain RPC congestion may cause timeouts or stale rate data
- Protocol smart contract unavailability on Base may result in incomplete APY data
- Very small USDC balances will likely trigger a gas-eats-yield skip signal

## How this service works

Base USDC lending APY. Should you park this wallet's USDC on Base? Snapshot of native USDC + ETH, then the same size-aware Aave V3 vs Morpho Gauntlet USDC Prime yield pick (USD per year, days to break even, skip if gas eats it). Not a deposit instruction.

## Output

Returns the wallet's current USDC and ETH balances on Base, the live lending APYs for Aave V3 USDC and Morpho Gauntlet USDC Prime, a size-aware recommended protocol, projected USD earnings per year, and the number of days required to break even on gas costs. Includes a skip recommendation if gas costs outweigh yield gains.
