How this service works
Free stable Base block sample. The paid $0.0027 API returns a normalized block header, gas fields, roots, size, and transaction hashes from one bounded read-only RPC call.
Output
Returns a normalized Base block header object containing block number, timestamp, gas limit, gas used, parent hash, state root, transactions root, receipts root, block size in bytes, and an array of transaction hashes for all transactions included in the block.
Example use cases
Monitor Base block gas usage
“Check the latest Base block header and tell me the gas limit, gas used, and how full the block was.”
Verify Base block transaction inclusion
“Fetch the current Base block header and give me the transactions root and the list of transaction hashes so I can confirm a transaction was included.”
Audit Base chain state for reconciliation
“Pull the most recent Base block header with the state root, receipts root, and block size — I need it for a reconciliation check.”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/base-block-sampleWhen to prefer
Choose this endpoint when you need structured, normalized Base blockchain block header data — including gas fields, Merkle roots, and transaction hashes — from a single bounded read-only call. Prefer this over raw RPC calls when you want pre-normalized output without managing Web3 provider connections. Best for agents that need chain-level metadata from the Base L2 network specifically rather than Ethereum mainnet.
Side effects
- Block not found or invalid block selector returns an error response
- RPC node unavailability may cause timeouts or 503 errors
- Malformed query parameters return 400 bad request
- Rate limiting on the free sample tier may return 429 too many requests
