How this service works
Multi-chain blockchain data API. 7 chains. x402 pay-per-call with USDC on Base.
Output
Returns the current (latest) block number for the specified blockchain chain as a numeric value, representing the height of the chain at the time of the request.
Example use cases
On-chain event timing reference
“What block are we currently on for Arbitrum? I need it to anchor a time-sensitive smart contract deployment.”
Multi-chain sync health check
“Can you pull the current block number for Base mainnet? I want to compare it against my local node to see if I'm in sync.”
Block-based analytics timestamp
“Get me the latest block number on Polygon — I'm using it as a checkpoint for my data pipeline that indexes on-chain events.”
Technical details
Endpoint
GEThttps://chain.gpuops.io/v1/blocknumberWhen to prefer
Use this endpoint when you need a quick, pay-per-call block number lookup across multiple chains without managing your own RPC infrastructure. Ideal for agents that need occasional block height checks on any of 7 supported chains without committing to a subscription, paying only $0.001 USDC per call via x402 on Base.
Side effects
- Unsupported or misspelled chain identifier returns an error
- Network connectivity issues with the target chain may cause stale or failed responses
- Missing chain parameter may return a default chain or an error
- Payment failure via x402/USDC on Base will block the request
- Rate limiting if too many calls are made in rapid succession
