How this service works
Get the current Base mainnet block number (latest chain height) for an autonomous agent.
Output
Returns a JSON object with the network identifier (e.g. 'eip155:8453' for Base mainnet) and the current block number as an integer (e.g. 36000000).
Example use cases
Confirm transaction finality on Base
“I just submitted a transaction on Base — can you check what the current block number is so I can figure out how many confirmations it has?”
Monitor Base chain progress in real time
“Keep an eye on the Base block number every minute and let me know once we've passed block 37000000.”
Sync smart contract logic to chain height
“What block is Base on right now? I need the current block height to calculate the deadline for my on-chain auction.”

Endpoint
GEThttps://api.mach.gallery/api/base/block-number?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-subscription, pay-per-call way to fetch the current Base block number without setting up API keys. Ideal for autonomous agents that need occasional on-chain timing data from Base (eip155:8453) and want to pay frictionlessly with USDC via x402.
Side effects
- Payment failure via x402 if USDC balance is insufficient — returns 402 Payment Required
- Network or RPC node outage causing unavailability — returns 5xx error
- Stale block number if underlying Base RPC node is behind — no explicit error, just slightly outdated value
