How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
Returns a JSON object containing detailed Ethereum block data, likely including the block hash, block number, timestamp, miner/validator address, gas limit, gas used, transaction count and/or transaction hashes, block reward, parent hash, and other standard Ethereum block header fields.
Example use cases
Verify transaction inclusion in block
“I need to check whether a transaction appeared in Ethereum block 19000000 — can you fetch the full block details from blockchain.com's explorer so I can inspect its transaction list?”
Audit historical block metadata
“Pull up the details for Ethereum block hash 0xd4e56740f876aef8c010b86a40d5f56745a118d0906a34e69aec8c0db1cb8fa3 from blockchain.com's explorer gateway — I need the miner, timestamp, and gas used.”
Monitor specific block for DeFi analysis
“Fetch the data for Ethereum block 18500000 on the ETH network from blockchain.com's explorer — I'm analyzing gas prices and miner rewards around that block for a DeFi report.”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/eth/block?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to look up a single Ethereum block by its exact hash or block number and want data from a reputable, blockchain.com-hosted explorer gateway. It is ideal for agents that need block-level metadata (miner, gas, timestamp, transactions) on Ethereum mainnet. Prefer it over raw RPC calls when you want a REST/JSON interface without managing your own Ethereum node or API key — and are comfortable with a per-call micropayment via x402.
Side effects
- Neither hash nor blockId provided — request rejected with validation error
- Block not found for given hash or block number — 404 or empty response
- Invalid hash format (not a valid hex string) — 400 bad request
- Block number out of range or negative — validation error
- Network field missing or set to unsupported chain — error response
- Payment not included or insufficient — 402 Payment Required
- Rate limiting or upstream node unavailability — 503 or timeout
