How this service works

A Bitcoin mainnet address: confirmed and unconfirmed balance in BTC and USD, transaction count, funded and spent totals, and its last 10 transactions with the net change for the address. Mainnet bech32 and legacy addresses only. Source: mempool.space. Information only, not financial advice.

Output

Returns a JSON object with the queried Bitcoin address, its confirmed and unconfirmed balances in BTC, USD, and satoshis, total BTC received and sent, total transaction count, the current BTC/USD spot price, a timestamp, and an array of recent transactions each with txid, net BTC change, timestamp, and confirmation status.

Example use cases

Verify incoming Bitcoin payment

“I'm expecting a payment to my Bitcoin address bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq — can you check if any transactions have come in recently and confirm the current balance?”

Monitor whale wallet holdings

“Check the Bitcoin balance and total transaction history for the address 1P5ZEDWTKTFGxQjZphgWPQUpe554WKDfHQ — I want to know how much BTC they're holding and what they've sent and received in total.”

Audit Bitcoin address for compliance

“Pull up the full balance details and transaction count for Bitcoin address 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy — I need the confirmed balance in BTC and USD and how many transactions it has made.”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/btc/address?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need on-chain Bitcoin address data including balance in both BTC and USD, historical send/receive totals, and recent transaction details — all in one call. It is backed by mempool.space and also returns the live BTC/USD price, making it more convenient than raw block explorer APIs. Prefer it over Solana or EVM wallet endpoints for Bitcoin-specific lookups.

Side effects

Invalid or malformed Bitcoin address returns an error
Address not found on mainnet returns empty data
Rate limiting or payment failure returns 402
mempool.space upstream outage may cause timeout or partial data
Unconfirmed transactions may have 0 balance if mempool is not synced
