How this service works
Fetch an Ethereum block header and transaction hashes by number, tag, or hex via eth_getBlockByNumber
Output
Returns the block header fields (number, hash, parentHash, timestamp, miner, gasUsed, gasLimit, difficulty, etc.) and a list of transaction hashes included in the specified block, sourced via eth_getBlockByNumber from a live Ethereum RPC.
Example use cases
Analyze miner activity patterns
“Can you check the last 10 Ethereum blocks and tell me which miners produced them and how many transactions were in each one?”
Track transaction finality across networks
“I need you to fetch the latest finalized block on Sepolia testnet and show me all the transaction hashes included in it.”
Monitor gas usage by block
“Pull the block header info for the most recent Base network block and let me know the gas used versus the gas limit.”
Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/block/22000000When to prefer
Use this endpoint when you need on-chain block-level data — headers, timestamps, miner info, or transaction hashes — for a specific block by integer, hex, or tag (latest/finalized/etc.) across Ethereum mainnet, Base, Avalanche, MegaETH, or Sepolia. Prefer this over general blockchain explorers when you need programmatic, structured block data without web scraping.
Side effects
- Block number does not exist yet (future block) — returns error or empty
- Invalid hex format for block number — 400 bad request
- Unsupported network value — validation error
- Network RPC timeout or node unavailability — 5xx error
- Block tag 'pending' may return null if no pending block exists
