Example prompt: What are the current DeFi savings rates for USDC on Base mainnet right now?

## When to prefer this

Use this endpoint when you need current DeFi savings/yield rates specifically on Base mainnet (or base-sepolia for testing) and are already operating within the x402 micropayment ecosystem. Prefer this over generic DeFi aggregators when you need programmatic, agent-callable rate data paid per-query in USDC. Best suited for agents making autonomous financial decisions about where to allocate stablecoin holdings on Base.

## Known failure modes

- Payment not received — returns HTTP 402 requiring $0.02 USDC payment via x402 protocol
- Invalid network parameter — unsupported network value may return an error
- Upstream on-chain data unavailable — may return 503 or empty rates if Base RPC is unreachable
- Rate data stale or missing — protocol may return null or empty rate fields if data refresh fails

## 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.
