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, baseFeePerGas, etc.) and an array of transaction hashes included in that block for the specified network.
Example use cases
Audit transaction activity in latest block
“Check the most recent Ethereum block and tell me what transactions were included — I need to verify some recent on-chain activity.”
Monitor gas usage across network blocks
“Pull the block header for the last finalized block on Ethereum and show me the gas used versus the limit — I'm tracking network congestion trends.”
Verify miner and block timing data
“Fetch block details for block 19500000 on mainnet and give me the miner address, timestamp, and all the transaction hashes so I can analyze block production timing.”
Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/block/:numberWhen to prefer
Use this endpoint when you need on-chain block metadata or the list of transaction hashes in a specific block on Ethereum, Base, Avalanche, Sepolia, or MegaETH. Prefer over raw RPC calls when you want a simple REST interface with predictable pricing. Best for agents that need to inspect block timestamps, gas usage, miner info, or enumerate transactions in a block without running a full node.
Side effects
- Block number not yet mined returns null or 404
- Invalid hex format for block number returns 400 validation error
- Unsupported network value returns 400 or 422
- 'pending' tag may return null on non-Ethereum networks
- Network RPC unavailable returns 500 or timeout
- Payment failure (x402) returns 402 Payment Required
