How this service works
Read the latest Base mainnet block and a bounded EIP-1559 fee history in one RPC batch, including gas utilization and priority-fee percentile samples.
Output
Returns the latest Base mainnet block details (block number, timestamp, gas used, gas limit, base fee per gas) along with a bounded EIP-1559 fee history array containing base fees and priority-fee percentile samples (e.g. 10th, 50th, 90th percentiles) across recent blocks, plus computed gas utilization ratios.
Example use cases
Pre-transaction gas fee check
“Before I submit this transaction on Base, can you check the current network conditions — specifically the latest block, the base fee, and what priority fees look like across the 25th, 50th, and 75th percentiles?”
Base network congestion monitoring
“I want to monitor Base mainnet gas utilization over the last 10 blocks — pull the EIP-1559 fee history and tell me if the network is congested or has capacity right now.”
DeFi bot fee calibration
“My trading bot needs to know the current Base mainnet baseFee and recent priority fee distribution so it can set an appropriate maxFeePerGas — can you grab the latest block and fee history?”
Technical details
Endpoint
POSThttps://apiacre.com/v1/crypto/base-network-statusWhen to prefer
Use this endpoint when you need a combined snapshot of current Base mainnet block state AND fee history in a single call, rather than making two separate RPC calls. Ideal for agents that need to calibrate gas pricing, monitor network congestion, or make real-time transaction submission decisions on Base L2 specifically. Prefer this over raw Ethereum RPC if you want a structured, pre-parsed response with percentile fee samples already computed.
Side effects
- Base RPC node temporarily unavailable — returns 5xx or timeout
- Invalid percentile values outside 0-100 range — returns 400 validation error
- Block history range too large — returns 400 with bounds error
- Network reorg or stale block during high congestion — may return slightly outdated block data
