₿ Mempool.space Bitcoin Scraper

🚀 Pull live Bitcoin chain data in seconds. One run returns the latest 15 blocks with mining pool, reward, fees, and transaction counts, plus on-demand fee, mempool, difficulty, address, and transaction lookups.

🕒 Last updated: 2026-06-04 · 📊 22 fields per block record · keyless public API · full Bitcoin mainnet coverage

Track the Bitcoin network without running a node or registering for an API key. This Actor reads directly from the public mempool.space REST API and returns clean, flat records for recent blocks, recommended fees, mempool congestion, the next difficulty adjustment, and lookups for any address or transaction.

Coverage spans the entire Bitcoin mainnet. Block data includes the mining pool, coinbase address, block reward, total fees, median and average fee rates, plus input and output totals straight from the chain.

🎯 Target Audience	💡 Primary Use Cases
Crypto analysts and traders	Fee timing and mempool congestion monitoring
Bitcoin researchers and educators	Block, pool, and reward analysis
Wallet and dashboard builders	Address balance and transaction lookups
Quant and data teams	Feeding chain metrics into models and reports

📋 What the Mempool.space Bitcoin Scraper does

Auto-detects what you want from your input and queries the matching mempool.space endpoint:

• Recent blocks (default) returns the latest blocks with height, hash, pool, reward, fees, and size.
• Recommended fees returns the five fee tiers in sat/vB.
• Mempool summary returns pending transaction count, virtual size, total fees, and current fee tiers.
• Difficulty adjustment returns progress, estimated change, remaining blocks, and the next retarget.
• Address lookup returns balance and confirmed and pending transaction stats for any Bitcoin address.
• Transaction lookup returns size, weight, fee, input and output counts, and confirmation status for any txid.

⚙️ Input

Field	Type	Description
mode	select	blocks (default), fees, mempool, or difficulty.
address	string	Optional Bitcoin address. When set, overrides mode and returns an address summary.
txid	string	Optional transaction ID. When set, overrides mode and returns a transaction.
maxItems	integer	Free users limited to 10. Paid users up to 1,000,000. Only blocks returns multiple rows.

Example 1 — latest blocks:

{ "mode": "blocks", "maxItems": 15 }

Example 2 — look up an address:

{ "address": "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa" }

⚠️ Good to Know: Only the blocks mode returns multiple rows (up to 15 most recent blocks). The fees, mempool, difficulty, address, and txid modes each return a single summary record. All values come straight from mempool.space and reflect the chain state at the moment of the run.
