How this service works
Free Base latest-block-height sample. The paid $0.0009 service returns the canonical decimal Base block number, timestamp, head age, and source provenance from a bounded read-only RPC batch.
Output
A JSON object containing the canonical decimal Base block number, the block timestamp, the age of the chain head (how long since last block), and source provenance metadata indicating which RPC endpoint provided the data.
Example use cases
Real-time Base chain monitoring
“Check the latest Base block height and tell me how old the chain head is — I want to make sure the network is keeping up.”
Timestamping a Base transaction
“What's the current Base block number and its timestamp? I need to anchor an event to the current chain state.”
Verifying Base node sync status
“Can you grab the latest Base block number and head age so I can confirm my node is in sync with the canonical chain tip?”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/base-block-height-sampleWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.0009) read-only lookup of the current Base chain tip with provenance metadata. Prefer it over Ethereum mainnet block height endpoints when your workflow is Base-specific. Useful for timestamping, sync verification, or chain monitoring without requiring a full RPC node setup.
Side effects
- RPC provider unavailable — returns an error or timeout if Base RPC nodes are unreachable
- Stale head age — during network congestion, head age may appear elevated but the response still succeeds
- Cloudflare tunnel disruption — the trycloudflare.com proxy may be temporarily unavailable, returning a 5xx error
- Rate limiting — excessive requests may be throttled by the underlying RPC batch endpoint
