Ethereum Latest Block Height
x402
Ethereum Latest Block Height is a paid API for AI agents from appearing-clinics-show-wrote.trycloudflare.com, paid per call via x402, price unknown, status down (last checked 2026-09-15).
Returns the current Ethereum mainnet canonical block height, timestamp, head age, and provenance from a verified batch.

How this service works
Free live Ethereum mainnet chain-tip sample. The paid $0.0008 API returns canonical block height, timestamp, head age, and provenance from one bounded verified batch.
Output
Returns the canonical Ethereum mainnet block height (block number), the block timestamp, the age of the chain head (how long ago the latest block was produced), and provenance metadata from a verified batch indicating the data source and integrity.
Example use cases
Real-time DApp sync check
“Can you check the current Ethereum block height and tell me how old the chain head is, so I can verify my DApp is in sync with mainnet?”
Blockchain monitoring dashboard
“Pull the latest Ethereum mainnet block number and timestamp for my monitoring dashboard — I need to know the chain tip is live and up to date.”
Smart contract deployment timing
“What's the current Ethereum block height and timestamp? I want to time my smart contract deployment relative to the current chain tip.”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/ethereum-block-height-sampleWhen to prefer
Choose this endpoint when you need a quick, lightweight lookup of the current Ethereum mainnet block height and chain tip age without constructing a full RPC call. It is ideal for monitoring, dashboards, or DApp sync checks where only the canonical block number and recency metadata are needed, and when cost-sensitivity matters (free sample, $0.0008 paid). Prefer a full Ethereum node RPC for deeper block data or custom queries.
Side effects
- Network or Cloudflare tunnel unavailability returns a 5xx error with no block data
- Chain data lag if the underlying node is behind mainnet — head age may be stale
- Free sample endpoint may return cached or bounded data rather than true real-time chain tip
- No input parameters accepted — any query parameters are ignored
