## 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 beggar-bot-stable-yields-lookup-base-mainnet-b0e0ca69
```

Example prompt: What are the current stable yield opportunities for USDC on Base mainnet right now? I want to see the best options available.

## When to prefer this

Use this endpoint when you need on-chain stablecoin yield data specifically for Base mainnet or Base Sepolia testnet, and you are equipped to pay micropayments via the x402 protocol in USDC. Prefer this over generic DeFi aggregators when you need programmatic, agent-callable yield lookups with per-call pricing rather than subscription-based access.

## Known failure modes

- Payment not received — x402 payment of $0.02 USDC on Base mainnet required before data is returned
- Invalid network parameter — only 'base' (default) or 'base-sepolia' are accepted
- Upstream DeFi data unavailable — protocol data sources may be temporarily unreachable
- Malformed request parameters — schema expects string properties
- Rate limiting or worker timeout on Cloudflare infrastructure

## How this service works
