How this service works
Return the latest Base mainnet block number from a bounded public RPC fallback set.
Output
Returns the current (latest) block number on Base mainnet as an integer, sourced from a bounded fallback set of public Base RPC endpoints.
Example use cases
Monitor Base chain liveness
“Check the current block number on Base mainnet and alert me if it hasn't advanced in the last 5 minutes.”
Sync confirmation for dApp
“Before submitting this transaction, can you grab the current Base mainnet block number so I can use it as a reference point?”
Blockchain data freshness check
“I need to know what block Base is currently at — fetch the latest block number from the mainnet RPC.”
Technical details
Endpoint
POSThttps://payne-machine-revenue-mcp.apayne1987.workers.dev/v1/base-block-numberWhen to prefer
Use this endpoint when you need a quick, low-cost lookup of the current Base mainnet block height without managing your own RPC node or API key. Ideal for agents needing a lightweight chain-tip reference for confirmation windows, freshness checks, or sequencing logic on Base L2.
Side effects
- All RPC fallback endpoints unavailable — service returns error
- Network timeout from upstream Base RPC nodes
- Stale block number if fallback nodes are lagging
- Invalid or missing input body causing 400-level error
- Payment not accepted — 402 if USDC payment header is missing or malformed
