Example use cases
Verify Bitcoin block confirmation
“Can you check Bitcoin block hash 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f and confirm it exists on the blockchain with its details?”
Audit block at specific height
“Pull up the Bitcoin block at height 840000 and tell me when it was mined, how many transactions it contains, and who mined it.”

Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/btc/block?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured Bitcoin block data (by hash or height) from a production-grade explorer API with pay-per-call pricing. Prefer it over running a full Bitcoin node or scraping block explorer websites when you need reliable, programmatic access to BTC block metadata without infrastructure overhead.
Side effects
- Invalid or malformed block hash (not 64 hex characters) returns a 4xx error
- Block height not yet mined or negative value returns not-found error
- Providing both hash and height simultaneously may return an error or ambiguous result
- Network or gateway timeout for very recent blocks not yet indexed
- Rate limit or payment failure returns 402 Payment Required
