## 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-607f5a57 -d '<json body>'
```

Example prompt: What are the current yield rates for USDC across major DeFi protocols — I want to see APY comparisons so I can decide where to park my stablecoins?

## When to prefer this

Use this endpoint when you need current stablecoin yield and APY data from DeFi protocols, particularly when building yield comparison tools, portfolio optimization agents, or DeFi monitoring dashboards. Prefer this when you need on-demand per-request pricing via USDC micropayments rather than a subscription-based data provider.

## Known failure modes

- Invalid or unsupported stablecoin symbol returns an error
- Protocol data unavailable returns empty or null result
- Payment failure due to insufficient USDC balance
- Rate limiting or upstream data source outage returns 503
- Malformed request body returns 400 error
