Example prompt: What's the current Chainlink oracle price for ETH/USD on Base right now?

## When to prefer this

Use this endpoint when you need a verified, tamper-resistant on-chain oracle price from Chainlink for a specific asset pair, especially for DeFi applications, smart contract logic, or any use case requiring blockchain-native price data rather than centralized exchange prices. Prefer this over CEX-based price APIs when on-chain verifiability matters.

## Known failure modes

- Unknown or unsupported trading pair name returns an error or empty result
- Invalid feed address returns a lookup failure
- Unsupported chain name causes a rejection or defaults unexpectedly to Base
- Network or RPC issues on the target chain can cause latency or timeouts
- Stale feed data may be returned if the Chainlink oracle has not updated recently
- Payment failure (402) if USDC balance is insufficient
