Inspects a historical Base mainnet block by number or resolves a canonical tag (latest, safe, finalized), returning transaction count, gas, fee, root hashes, and head distance.

How this service works
Get and inspect one historical Base mainnet block by exact number or a latest, safe, or finalized tag, returning its header timestamp, transaction count, gas use, base and blob fees, state and receipt roots, confirmations, and head-distance evidence.
Output
Returns a structured JSON object containing block number, hash, timestamp, transaction count, gas used, gas limit, base fee per gas, state root, receipts root, transactions root, and the distance (in blocks) from the current chain head. Also indicates whether the block is canonical, safe, or finalized.
Example use cases
Audit historical Base block activity
“Pull the details for Base mainnet block 17000000 — I need the transaction count, gas used, and the state root hash for an audit.”
Resolve current finalized block
“What's the latest finalized block on Base mainnet right now? Give me its number, timestamp, and how many transactions it contains.”
Monitor block distance from chain head
“Check Base block 18999999 and tell me how far back it is from the current head, along with its gas limit and fee data.”
Technical details
Endpoint
POSThttps://apiacre.com/v1/crypto/base-block-inspectWhen to prefer
Choose this endpoint when you need detailed metadata about a specific Base mainnet block — including gas, fees, roots, and head distance — without running your own RPC node. It is ideal for agents auditing on-chain activity, verifying block finality, or monitoring chain progression on Base L2 specifically (not Ethereum mainnet or other EVM chains).
Side effects
- Block number not found or not yet mined returns a 404-style error
- Invalid block tag (not latest/safe/finalized) returns a validation error
- Block number exceeds current chain head returns an out-of-range error
- Network or RPC timeout causes a 503 or timeout response
- Malformed request body returns a 400 bad request error
