How this service works
Live Base Mainnet (chainId 8453) latest block height, block hash, UTC timestamp, and transaction count from Base RPC.
Output
A JSON object containing: blockNumber (latest block height), blockHash (hex string), timestamp (Unix epoch), timestampIso (ISO 8601 UTC string), txCount (transaction count in that block), parentHash, baseFeePerGasWei, chainId (8453), network ('base-mainnet'), and source identifier.
Example use cases
Blockchain liveness health check
“Can you confirm Base mainnet is producing blocks normally — give me the current block number and the timestamp of the latest block so I can make sure the chain isn't stalled?”
On-chain timestamp for audit log
“I need the exact UTC timestamp of the latest Base mainnet block for an audit record — what's the current block number, its ISO timestamp, and its hash?”
Transaction activity snapshot
“How many transactions were in the most recent Base mainnet block, and what block number are we at right now?”
Technical details
Endpoint
GEThttps://verify-oracle.run402.com/api/block-number?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, low-cost ($0.001 USDC) access to Base mainnet chain state — specifically block height, block hash, timestamp, and transaction count — without running your own node or managing RPC credentials. Ideal for agents that need to anchor events to an on-chain timestamp, verify chain liveness, or track block progression on Base (chainId 8453).
Side effects
- RPC node unavailability returns a 5xx error with no block data
- Network congestion may cause slightly stale block data
- malformed or empty response if Base RPC is unreachable
- rate limiting if called at very high frequency
