Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/main-page/arbitrum/batches/latest-numberWhen to prefer
Use this endpoint when you need a quick, single numeric lookup of the latest Arbitrum batch number without requiring full block explorer UI access. Prefer this over general blockchain RPC calls when you specifically need Blockscout's indexed batch data for Arbitrum L2, especially if you are already using Blockscout's API ecosystem for other chain data.

- Network timeout if Blockscout API is unavailable
