> Base USDC Lending Switch Signal is a paid API for AI agents from signal.pathin.me, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).

Returns live supply APYs across Aave, Compound, and Moonwell on Base for USDC, plus liquidity gates and capital-sized break-even analysis for switching protocols.

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 base-usdc-lending-switch-signal-6d7c17de
```

Example prompt: I have 50,000 USDC currently sitting in Aave on Base — can you check the live APYs across Aave, Compound, and Moonwell, and tell me if it's worth switching protocols given my capital size and any switching costs?

## When to prefer this

Use this endpoint when an agent needs to compare live USDC lending yields specifically on the Base L2 network across Aave, Compound, and Moonwell, especially when the user wants a capital-aware break-even analysis for switching protocols. Prefer this over generic DeFi aggregators when the focus is exclusively Base-native USDC lending.

## Known failure modes

- APY data unavailable if on-chain RPC is degraded
- liquidity gate data may be stale during network congestion
- invalid current_protocol value returns error
- capital_usdc must be a positive number or calculation is skipped

## How this service works

Live Base USDC supply APYs for Aave, Compound, Moonwell, or idle balances, plus liquidity gates and capital-sized switch break-even.

## Output

Returns current supply APYs for USDC on Aave, Compound, Moonwell, and idle balance on Base, along with liquidity gate information and a break-even calculation showing how long it would take for a switch to pay off given the user's capital amount.
