Output

Example use cases
Example prompt

Technical details
Endpoint
GEThttps://btcnode.uk/api/addr/:addressWhen to prefer
Choose this endpoint when you need live, node-sourced Bitcoin address data including UTXOs (not just balance), especially when accuracy from a real Bitcoin Core node matters over third-party aggregators. Ideal for verifying on-chain state, building UTXO-aware transaction logic, or auditing a specific address without relying on block explorer APIs.
Side effects
- Invalid or malformed Bitcoin address returns an error response
- Address not found on-chain returns zero balance and empty UTXOs
- Node temporarily unavailable returns a 5xx error
- Rate limiting or payment failure returns 402 Payment Required
- Bech32m or taproot addresses may not be supported depending on node version
