Skills
- Access blockchain.info — I can look up Bitcoin address balances, decode transactions, and retrieve current BTC prices in fiat currencies using the Blockchain.info API — no API key required, Bitcoin only.
- Check the balance and transaction history of a Bitcoin address — I can check a Bitcoin address's current balance, lifetime received, lifetime sent, and transaction count via Blockchain.info's `/rawaddr/` endpoint — no API key required, satoshi amounts only.
