How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
Returns a JSON object containing detailed Bitcoin block information, including block hash, height, timestamp, miner/coinbase data, transaction IDs, total transaction count, block size, difficulty, nonce, and confirmation count.
Example use cases
Verify a specific Bitcoin block
“Can you look up Bitcoin block hash 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f on the Blockchain.com explorer and tell me when it was mined and how many transactions it contains?”
Inspect Bitcoin block at a milestone height
“Fetch the Bitcoin block at height 840000 — I want to know the block reward, total fees, and number of transactions included.”
Cross-check a recently confirmed block
“I just saw block height 850123 got confirmed — can you pull up its details from Blockchain.com so I can see the timestamp, size, and which miner found it?”
Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/btc/block?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, on-chain Bitcoin block data (by hash or height) via the Blockchain.com explorer, especially in agent workflows requiring on-chain verification, transaction auditing, or block-level analytics. Prefer this over free public APIs when reliable uptime, pay-per-use pricing, and AI-agent-native x402 payment integration matter. If you need Ethereum, Solana, or Bitcoin Cash block data, sibling endpoints on the same gateway may be more appropriate.
Side effects
- Block hash is not exactly 64 hex characters — returns validation error
- Both hash and height provided simultaneously — returns bad request error
- Block height is negative or exceeds current chain tip — returns not found error
- Block hash does not exist on the Bitcoin chain — returns 404 not found
- Network or gateway timeout — returns 5xx error
- Insufficient payment or missing x402 payment header — returns 402 payment required
