How this service works
Watch a Bitcoin address in a loop and get only new transactions since your last call, with direction, net BTC, confirmations and time, plus the balance. First call returns recent transactions and a cursor; pass it back next time. For deposit detection and treasury or whale watching.
Output
Returns a list of new transactions since the provided cursor (or recent transactions on first call), each with direction (in/out), net BTC amount, confirmation count, and timestamp. Also includes the current wallet balance and a new cursor to pass on the next call to retrieve only subsequent transactions.
Example use cases
Deposit detection for crypto payment gateway
“Watch Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf for new incoming deposits — show me any transactions that arrived since cursor abc123, the direction, how much BTC, and confirmation count.”
Treasury wallet balance and activity tracking
“Poll our company treasury BTC address bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq for new transactions. We last checked with cursor xyz789 — just show me what's new since then, the net BTC, and the current balance.”
Whale wallet surveillance
“Monitor the known whale address 3FZbgi29cpjq2GjdwV8eyHuJJnkLtktZc5 and fetch the last 20 transactions — I want to see inflows and outflows, confirmation counts, timestamps, and current holdings.”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/btc-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need incremental, deduplicated Bitcoin transaction polling for a specific address — especially for deposit detection in payment flows, treasury monitoring, or whale watching. The cursor mechanism makes it ideal for agents that run on a schedule and need only new activity since the last check, avoiding re-processing of already-seen transactions. Prefer it over full blockchain explorers when you want a lightweight, pay-per-call approach without managing your own node or API keys.
Side effects
- Invalid or malformed Bitcoin address returns an error response
- Stale or tampered cursor may return unexpected results or an error
- Address with no transaction history returns an empty transaction list
- Network or upstream blockchain data source unavailability causes a service error
- Limit value out of acceptable range may be rejected or silently capped
