Example prompt: Can you look up the category fees on Base mainnet from Beggar Bot so I can see the full breakdown of fee tiers for USDC transactions?

## When to prefer this

Use this endpoint when you need a structured fee breakdown by category for Base mainnet USDC activity and are already integrated with the x402 micropayment protocol. Prefer this over manual on-chain fee lookups when you need a pre-categorized, queryable fee schedule without parsing raw blockchain data.
