## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-northeastdealintel-com-dd9439ba
```

Example prompt: Who owns 245 Park Avenue in New York, and how long have they held the deed? I want the ownership aging signal too.

## When to prefer this

Use this endpoint when you need to quickly identify who owns a specific Northeast US commercial property, how long they have held it, and whether ownership tenure signals a potential selling opportunity. Prefer this over general public records searches when you need structured, machine-readable output with an aging signal baked in, especially as part of a deal prospecting or lead scoring workflow.

## Known failure modes

- Address not found in deed records — returns empty or null owner data
- State not recognized or outside Northeast US coverage — returns error or no data
- Ambiguous address string that cannot be matched — may return wrong or no record
- Rate limiting or payment failure via x402 — returns 402 Payment Required
- Malformed query parameters — returns 400 Bad Request

## How this service works

## Output

Returns the current owner name, the number of years they have held the property, and an aging signal derived from 100K+ deed records — useful for assessing deal momentum, distress indicators, or seller motivation.
