## 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-yield-history-base-mainnet-7f3565da
```

Example prompt: Can you pull the historical yield data for USDC on Base mainnet so I can see how rates have changed over time?

## When to prefer this

Use this endpoint when you need historical yield data specifically for assets on Base mainnet (or Base Sepolia testnet), particularly USDC, and are operating in a micropayment-capable x402 environment. Prefer this over generic DeFi analytics APIs when you need on-chain Base network yield history with pay-per-call pricing and no subscription required.

## Known failure modes

- Payment not provided or insufficient — returns HTTP 402 requiring $0.02 USDC payment via x402 protocol
- Invalid network parameter — unsupported network values beyond 'base' and 'base-sepolia' may return errors
- Malformed query properties input — poorly structured properties parameter may yield unexpected results or errors
- Service unavailable — Cloudflare Workers outage could cause 5xx errors
- No historical data available — if the asset or time range has no yield data, response may be empty or null

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.
