## 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 kiteendpoints-ai-stablecoin-yield-api-b29b6c13 -d '<json body>'
```

Example prompt: What are the best current stablecoin yield rates available across DeFi protocols — I want to compare APYs for USDC, USDT, and DAI to find the highest safe return?

## When to prefer this

Use this endpoint when an agent needs current stablecoin yield rates across DeFi protocols and wants a consolidated lookup rather than querying individual protocol APIs. Best for financial planning, yield comparison, or portfolio optimization involving stablecoins. Prefer over manual on-chain queries when speed and aggregation matter.

## Known failure modes

- Payment not received — 402 response requiring USDC payment on Base chain
- Invalid input schema — malformed request body returns 400
- Data provider unavailable — upstream DeFi data source down, returns 503
- Rate limit exceeded — too many requests in short window
- Stale data — yield rates may lag real-time on-chain activity

## How this service works
