Network info
GET/api/chain/network-info
Batches eth_chainId, eth_blockNumber, eth_gasPrice, and the latest block header into one round-trip, and adds the network's characteristics: layer, stack, block time, native currency, and ENS/mempool/indexed availability. Three fields govern how you read other endpoints: avg_block_time_ms (cadence runs ~12s to ~100ms, so size block ranges from it, not Ethereum priors), stale with head_age_seconds (a frozen node looks like an idle chain otherwise), and gas_price (excludes L1 data cost on L2s).
