How this service works
Paid AI-agent access to Blockchain.com Explorer API
Output
A JSON array of Bitcoin block objects, each containing metadata such as block height, block hash, timestamp, transaction count, and miner details. Results are ordered descending by block height (newest first), capped at up to 50 blocks per call. Includes cursor information for further pagination.
Example use cases
Monitoring latest Bitcoin block production
“What are the 10 most recently mined Bitcoin blocks right now? Grab them from the chain tip on blockchain.info.”
Auditing a specific Bitcoin block range
“I need to review the 50 Bitcoin blocks starting from block height 800000 going backward — can you fetch those from the blockchain.info explorer?”
Building a Bitcoin block history feed
“Fetch me 25 Bitcoin blocks going back from height 850000 so I can display them in a historical block explorer feed.”
Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/btc/blocks?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to enumerate or paginate through Bitcoin blocks by height using a trusted, established block explorer (blockchain.info). Prefer this over generic Bitcoin RPC nodes when you want a REST/JSON interface without running your own node, and when per-call micropayment billing via x402 is acceptable. Best for read-only exploration, auditing, and data aggregation use cases on the Bitcoin chain.
Side effects
- Invalid 'after' cursor (block height out of range) — returns error or empty list
- 'limit' exceeds maximum of 50 — clamped or rejected with validation error
- Payment failure via x402 protocol — 402 Payment Required response
- Network timeout or gateway unavailability — 5xx error
- Requesting a block height beyond the current chain tip — returns empty or error
