## 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 httpay-defi-yields-api-116a3caa -d '<json body>'
```

Example prompt: What are the top DeFi yield opportunities on Base right now — show me the best APY rates across all protocols so I can decide where to put my USDC?

## When to prefer this

Choose this endpoint when you need live DeFi yield data specifically for the Base blockchain without setting up API keys or subscriptions. Ideal for agents that need on-demand, pay-per-call access to yield intelligence using USDC micropayments via x402. Prefer this over DeFiLlama's direct API when you want a pre-integrated, x402-compatible interface or when building autonomous agents that manage their own API payments.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required
- DeFiLlama upstream data unavailable — 502 or 503 error
- Rate limiting or network congestion on Base — delayed or failed payment
- No yields data available for the requested filter — empty result set
- Invalid request parameters — 400 Bad Request
