How this service works
Arbitrum One rollup batch postings to Ethereum L1 and the L1 gas they incurred: the latest SequencerBatchDelivered events on the SequencerInbox with batch number, L1 block and time, data location (blob or calldata), poster, execution gas, blob gas, gas prices and fees in ETH, plus totals. Read from Ethereum mainnet via Etherscan API V2.
Output
Returns a JSON object with the chain name, number of batches, source URL, per-batch details (batch number, tx hash, L1 block, poster, timestamp, data location, blob gas used, execution gas used, blob fee in ETH, execution fee in ETH, total L1 fee in ETH, gas price in Gwei, blob gas price in Gwei, delayed messages read), aggregated totals (blob fee, execution fee, total L1 fee in ETH), sequencer inbox address, L1 tip block, and the time the data was checked.
Example use cases
L2 cost analysis for DeFi protocol
“Show me the last 10 Arbitrum rollup batches with their total L1 fees and blob gas usage so I can analyze how much the sequencer is spending on Ethereum.”
Monitoring Arbitrum batch sequencer activity
“Check the most recent Arbitrum batch submissions to L1 and tell me the batch numbers, timestamps, and who the poster address is.”
Comparing blob vs execution fees over recent batches
“Fetch the latest 7 Arbitrum L2 rollup batches and break down the blob fee versus execution fee in ETH for each one.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/arbiscan-l2-rollup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Arbitrum One rollup batch submission data from Ethereum L1, including granular cost breakdowns (blob fees vs execution fees) sourced from Etherscan/Arbiscan. It is ideal for cost monitoring, sequencer analytics, and L2 infrastructure research without requiring an API key or signup. Prefer this over generic Ethereum RPC calls when you specifically need parsed, aggregated Arbitrum rollup batch metadata.
Side effects
- Invalid batches parameter (outside 1–10 range) may return an error or default
- Upstream Etherscan API unavailability causes data fetch failure
- Stale or delayed data if Etherscan indexing lags behind chain tip
- Payment failure results in no charge and no data returned
