FAQ

Questions BlockCypher owners ask.

  • 01

    Can I check the balance of a specific address without fetching all its transaction history?

    Yes! Use the get_address_balance capability. It provides a lightweight response containing only the balance and basic metadata for the specified coin and chain.

  • 02

    How do I find the current block height and fee estimates for Bitcoin?

    Simply use the get_blockchain capability with 'btc' as the coin and 'main' as the chain. It will return the latest block height, hash, and current network fee tiers.

  • 03

    Is it possible to generate a new wallet address for testing purposes?

    Yes. The generate_address capability allows you to create a new public/private keypair and address for any supported chain (e.g., 'btc' on 'test3' or 'bcy' on 'test').
