Lookup BSV Address
Look up BSV address information using WhatsOnChain API.
Status
Complete - All tests passing
When to Use
- Check address balance
- View transaction history
- List unspent outputs (UTXOs)
- Verify address activity
Usage
# Balance, UTXOs, and history (default granularity: all)
bun run /path/to/skills/lookup-bsv-address/scripts/lookup.ts <address>
# Balance only
bun run /path/to/skills/lookup-bsv-address/scripts/lookup.ts <address> balance
# Transaction history (tx_hash + height)
bun run /path/to/skills/lookup-bsv-address/scripts/lookup.ts <address> history
# Unspent outputs (outpoint + value + block height)
bun run /path/to/skills/lookup-bsv-address/scripts/lookup.ts <address> utxos
# JSON output (for scripting / reconciliation)
bun run /path/to/skills/lookup-bsv-address/scripts/lookup.ts <address> all --json
The positional granularity selects which sections to fetch: balance, history,
utxos, or all (default). Only the requested endpoints are called.
API Endpoints
WhatsOnChain Address API:
- Balance:
GET /v1/bsv/main/address/{address}/balance - History:
GET /v1/bsv/main/address/{address}/history - UTXOs:
GET /v1/bsv/main/address/{address}/unspent
Response
balance: confirmed + unconfirmed satoshis, plustotalBsv.utxos: each unspent output as{ outpoint, satoshis, height }, withutxoCountandutxoTotal(the UTXO total reconciles against the balance).history: each transaction as{ txid, height }, withhistoryCount.
Example
$ bun run lookup.ts 19Ao4zVRF6yzRaxiSHD34LCw7fBFn9nrDP utxos
Address: 19Ao4zVRF6yzRaxiSHD34LCw7fBFn9nrDP
UTXOs: 1 (216919 satoshis)
