Blockchair Multichain Stats Scraper

Blockchair Multichain Stats Scraper

Scrape blockchain stats for Bitcoin, Ethereum, and 17 more chains from Blockchair. Get market data, mempool size, difficulty, and node counts in one flat row per chain. No API key. Export to CSV, JSON, Excel, or XML.

Blockchair's API limits free requests and needs a key for anything serious. This Actor reads the public stats pages directly, so you can pull current blockchain metrics for up to 20 chains in a single run. Each chain returns one row with its market data, mempool, difficulty, and node counts.

Who uses it	What they scrape Blockchair for
Crypto analysts	Compare on-chain activity across multiple blockchains in one dataset
Traders	Monitor mempool size and transaction fees before placing orders
Researchers	Track network difficulty and hash rate over time for academic work
DApp developers	Check node counts and block times to choose the best chain for deployment

What it does

This Actor collects blockchain statistics from Blockchair for the chains you select and returns each chain as one flat row.

• ⛓️ 20 supported chains: Bitcoin, Ethereum, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash, Monero, Cardano, Ripple, Stellar, Tezos, EOS, Tron, Polkadot, and more.
• 📊 One row per chain: market cap, price, 24h volume, mempool size, difficulty, hash rate, node count, and block time.
• 🔢 Batch or single chain: select one chain or up to 20 in a single run, with a maxItems limit for free users.
• 📁 Flat export: every chain becomes one row in CSV, JSON, Excel, or XML, ready for spreadsheets or databases.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

Then prompt it in plain language to run the scraper and read back the results.

Troubleshooting

Why am I getting no results?

Check that you selected at least one chain in the input. Also ensure maxItems is set to at least 1. If the problem persists, Blockchair may be temporarily unavailable.

Why did I get an error about maxItems?

Free users are limited to 10 chain stats per run. If you need more, upgrade your Apify plan or reduce the number of chains.

Why is the data different from Blockchair's website?

The Actor scrapes the public stats pages, which may update every few minutes. The data should match closely, but there may be a small delay.

Can I scrape a chain that is not in the list?

No, the Actor only supports the 20 chains listed in the input schema. If you need another chain, contact the developer.
