Example prompt: Can you get me a relay quote from Beggar Bot for a Base mainnet transaction so I know what the relay fee will be before I proceed?

## When to prefer this

Use this endpoint when you need a relay quote specifically for Base mainnet (or base-sepolia testnet) transactions processed via the x402 protocol through Beggar Bot. Prefer this over generic fee estimators when you need Beggar Bot's specific relay pricing before committing to a paid /v1/verify, /v1/risk, or /v1/receipt call.
