How this service works
Live block summary by number, hex, or tag (latest/earliest/pending/safe/finalized; default latest): number, hash, parent, timestamp (unix + ISO), transaction count, gas used/limit, base fee and miner. Reads live on-chain data with automatic endpoint fallback.
Output
Returns a structured block summary including: block number (decimal and hex), block hash, parent hash, unix timestamp and ISO 8601 timestamp, transaction count, gas used, gas limit, base fee in wei, and miner address. Data is read live from the specified EVM chain with automatic endpoint fallback.
Example use cases
Monitor latest Ethereum block activity
“What is the latest Ethereum block? I need the block number, timestamp, transaction count, and base fee.”
Inspect specific block on Base
“Pull up details for block 15000000 on Base — I want the hash, miner, gas used, gas limit, and how many transactions were in it.”
Track finalized block for reconciliation
“Get me the finalized block on Arbitrum — I need the block number, timestamp, and transaction count for my reconciliation report.”
Technical details
Endpoint
POSThttps://chain.openverbs.com/v1/blockWhen to prefer
Use this endpoint when you need a comprehensive block-level snapshot from a live EVM chain — including gas, miner, timestamps, and transaction count — without constructing raw RPC calls. Prefer it over raw JSON-RPC when you want automatic endpoint fallback across Ethereum, Base, Arbitrum, Optimism, or Polygon, and need clean parsed output including both unix and ISO timestamps.
Side effects
- Invalid block number or tag returns an error indicating the block was not found
- Unsupported chain name returns a validation error listing accepted chains
- Pending block tag may return null fields if the chain does not support it
- Network or RPC outages may cause delayed responses even with automatic fallback
- Hex block numbers must be properly formatted (0x prefix) or a parsing error is returned
