How this service works
Primary-source verifiable x402 API oracle on Base Mainnet USDC.
Output
A JSON object containing: blockNumber (current Base Mainnet block height as integer), blockHash (0x-prefixed hash string), timestamp (Unix epoch of the block), txCount (transaction count in the block), chainId (8453), network ('base-mainnet'), and source ('base-mainnet-rpc').
Example use cases
Real-time blockchain height check
“Can you tell me the current block number on Base Mainnet and when that block was mined?”
On-chain state verification for dApp
“I need to verify the latest Base Mainnet block number, its hash, and how many transactions it contained — pull that directly from the chain.”
Monitoring Base chain liveness
“Is Base Mainnet still producing blocks? Fetch the latest block number and timestamp so I can confirm the chain is live and moving.”
Technical details
Endpoint
GEThttps://penger-oracle.run402.com/api/block-number?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiably sourced, payment-gated current block number from Base Mainnet (chainId 8453) with accompanying metadata (hash, timestamp, tx count) rather than relying on a free or unauthenticated RPC. Ideal for agents needing cryptographically auditable on-chain state snapshots with provenance guarantees via x402.
Side effects
- RPC node unavailability may return a 503 or timeout
- Payment verification failure (x402 payment not confirmed) returns 402
- Malformed or missing USDC payment header causes rejection
- Transient Base RPC latency may cause delayed or stale responses
