## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

## Nassau County NY Liens: Tax, Mechanics, Judgment & UCC

Search **Nassau County, New York** recorded liens by debtor, lender or document number. Get federal and state tax liens, mechanics liens, judgments, lis pendens and UCC filings with debtor and creditor names, amounts, addresses, property data, dates and document numbers as flat rows.

Nassau County is the largest Long Island jurisdiction and is **not** part of NYC ACRIS. This actor covers the Nassau County Clerk recorded-document index directly, including the county UCC department, the judgment and lien department, and lis pendens. It does not use the New York State Department of State UCC system or the NYC ACRIS borough feed.

Here is one real record from this actor.

### Comparison with other Apify actors

No dedicated actor for this source on the Apify Store as of November 2026. We searched the public Store on 2026-11-06 with queries including "Nassau County New York lien", "Nassau County recorder" and "Nassau County ucc", and we reviewed the listings for this source and data type. Broader actors exist: `shelvick/property-deed-records` searches deed and lien records from county recorder indexes. Their listings do not name this source, so we could not confirm that they cover it. Store listings change, so run the same search before you rely on this.

### FAQ

**Is Nassau County part of NYC ACRIS?**

No. Nassau is a separate county and its Clerk maintains a separate recorded-document index. NYC ACRIS covers Bronx, Kings, New York, Queens and Richmond only.

**Does this use the New York State UCC system?**

No. Data comes from the Nassau County Clerk index, including county-recorded UCC filings, judgments and liens. The New York State Department of State UCC system is a different source.

**Can I search by lender or secured party?**

Yes. Use `securedPartyNames`. The actor filters results to the secured-party, plaintiff, grantee or mortgagee side.

**Can I get only new liens without releases?**

Yes. Set `includeReleases: false`. Release, satisfaction, discharge, termination, withdrawal and cancellation records are then skipped.

**Can I look up one document number?**

Yes. Use `searchMode: "document"` and `documentNumbers`. Prefix matches are rejected; only the exact number is returned.

**Does the actor return document images?**

No. It returns the public index detail, parties, amounts and property data. Images and certified copies are not downloaded or sold.

**Is this an FCRA consumer report?**

No. This is public-record research for business, lending, KYB and due-diligence workflows.

## CLI example

```bash
echo '{
  "securedPartyNames": [
    "COMMISSIONER OF TAXATION"

  "lienTypes": [

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,lienintel/nassau-county-ny-lien-filings"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
