Kanpu Data API · for professionals
If you locate people or money for a living — private investigators, skip tracers, heir finders, asset-recovery services — Kanpu gives you aggregated US state unclaimed-property search through a single API, for one flat annual price.
API access is our Enterprise tier. We schedule a short call first to understand your use case and confirm it complies with state regulations, then set you up with a key. Email api@kanpufund.com to start.
Just sourcing deals? The Pro tier ($49.99/mo) gives PIs and small businesses 50 searches/day plus a multi-person research tool — no API needed.
There is no single place to buy every state's bulk unclaimed-property data. Most states don't sell bulk data at all — they only offer a manual web search. The handful that do sell it charge separately, and the totals add up fast:
| Source | What it costs | Coverage |
|---|---|---|
| Wyoming bulk file | $1,000 / yr | 1 state |
| Michigan (registration to access) | $1,200 | 1 state |
| Oregon Finder's List | $150 | 1 state |
| North Dakota list | $150 | 1 state |
| Nevada + Louisiana lists | $25 + $50 | 2 states |
| ~40 other states | not sold in bulk | 0 |
| Kanpu Data API | $500 / yr | aggregated |
Assembling the paid feeds alone runs past $2,500/yr and still leaves ~40 states you can't buy at all. Kanpu aggregates the free and paid sources, plus states that offer no bulk feed, behind one key.
Add asset and unclaimed-property checks to skip traces and background work without a stack of state subscriptions.
Screen decedents and heirs across states in one call.
Cross-reference names against public unclaimed-property records at volume.
Offer “find money owed to you” features on top of one integration.
POST a name (and optional state filter) and get back structured matches. Example:
POST https://api.kanpufund.com/v1/search
Authorization: Bearer <your-api-key>
Content-Type: application/json
{ "name": "Jane A. Doe", "priorNames": ["Jane Smith"], "states": ["CA","TX"] }
→ { "matchCount": 3,
"results": [
{ "owner": "DOE JANE A", "holder": "BANK OF AMERICA", "state": "CA",
"propertyType": "checking account", "amount": 4820.55 }
] }
Endpoint and schema shown for reference; provisioned per key. The free public lookup at kanpufund.com is rate-limited to a few searches per day — the API tier removes that limit for licensed, paying users.
Email api@kanpufund.com with your business name and use case. We'll issue a key and an invoice for $500/year.
