How this service works
Bitcoin address lookup for agents: confirmed and pending balance in BTC and USD, total received and sent, transaction count and the latest transactions with net amount, confirmations and fee. Works for bc1 (SegWit, Taproot), 1 and 3 addresses on Bitcoin mainnet. Use to check a payment, a treasury or a counterparty wallet.
Output
Returns confirmed and pending balance in both BTC and USD, total BTC received and sent over the address's lifetime, overall transaction count, and a list of recent transactions (up to 25) each with net amount, number of confirmations, and fee paid.
Example use cases
Verify incoming customer payment
“I need to confirm that the payment from our customer landed — can you check if Bitcoin address bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq has received any new transactions in the last 10 blocks and what the confirmed balance is right now?”
Monitor treasury wallet balance
“Check our company treasury wallet at 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy and tell me the total confirmed BTC balance, the USD equivalent, and how many transactions it has received in total.”
Audit counterparty wallet before deal
“Before I finalize this deal, can you look up Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na and show me its full transaction history — I want to see total sent, total received, and the last 25 transactions with fees and confirmations.”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/btc-address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain Bitcoin balance and transaction data for a specific address, particularly when you need both BTC and USD values together with per-transaction details like fees and confirmations in a single call. Prefer it over raw blockchain explorers when you need structured, agent-ready JSON output. Suitable for bc1 (SegWit/Taproot), legacy (1xxx), and P2SH (3xxx) mainnet addresses.
Side effects
- Invalid Bitcoin address format returns an error (non-bc1/1/3 addresses, testnet addresses)
- Address with no transactions may return zero balances
- Rate limiting or upstream blockchain data provider downtime
- Limit parameter out of range (above 25 or below 0) may return an error
- Mainnet-only — submitting a testnet address will fail or return incorrect data
