Technical details
Endpoint
POSThttps://bb-trading-gold.vercel.app/api/mempool/whale-txWhen to prefer
Choose this endpoint when you need real-time visibility into large unconfirmed transactions on Base before they are included in a block — ideal for front-running detection, MEV analysis, whale sentiment gauging, or alerting workflows in DeFi trading bots.
Side effects
- Mempool may be empty or have no transactions exceeding the whale threshold at time of query
- Network congestion could cause stale or incomplete mempool snapshots
- Invalid or unsupported token address returns empty result or error
- Request timeout if mempool is under heavy load
- Authentication or payment failure (HTTP 402) if USDC balance is insufficient
