## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## County Property Appraisal Lookup — 15 States (1,100+ counties)

Look up official **county property-appraisal records by address** across 27
Mississippi counties, returning normalized parcel data for business-property
due diligence, real-estate underwriting, and portfolio checks:

- **parcel** id, **property address**, **appraised value**, **land value**,
  **improvement value**, **total value**, **tax year**, **property class**
- **owner (organization only)** — see the data-scope note below

Search by **address** (street name + optional house number) or do a direct
**parcel-key** lookup. No API keys, no login.

### Why this actor

County assessor rolls are public but fragmented — every county a different
site. This actor normalizes the counties hosted on the **Delta Computer
Systems** public appraisal platform (one consistent source across ~28 MS
counties) into a single clean schema, so you can pull assessed values
programmatically instead of scraping each county by hand.

Typical uses: compare a listing/asking price to the county's own appraised
value, pull the real tax basis for underwriting, or verify a business's
real-property holdings.

### Data scope — organization owners only (by design)

Owner names appear on the public roll, but for residential parcels those are
private individuals. **This actor never returns a natural-person owner name.**
The `ownerOrg` field is populated only when the owner reads as an organization
(LLC, INC, CHURCH, COUNTY, HOSPITAL, etc.); for everyone else it is `null`.
Everything else returned is parcel-level public record. This keeps the actor to
**business-property** data — it is not a skip-tracing or homeowner-lookup tool.

### Input

| Field | Type | Description |
|---|---|---|
| `county` | string (required) | County name (`Forrest`, `Lamar`, …) or Delta code (`MS18`). |
| `street` | string | Street NAME only (e.g. `Hardy`). Omit if using `parcelKey`. |
| `number` | string | Optional house number to narrow the search. |
| `parcelKey` | string | Delta detail key for a direct parcel lookup. |
| `maxResults` | integer | Max parcels per run (default 25). |

### Output fields

| Field | Description |
|---|---|
| `county` | County the record came from. |
| `parcel` | County parcel / PPIN. |
| `propertyAddress` | Situs address as published. |
| `ownerOrg` | Owner name **only when it's an organization**; `null` otherwise. |
| `appraisedValue` | Best single roll value (USD) — total where published. |
| `landValue` / `improvementValue` / `totalValue` | Value components where the roll splits them. |
| `taxYear` | Assessment/tax year. |
| `propertyClass` | County property-class code. |
| `sourceUrl` | Link to the official parcel record. |
| `retrievedAt` | Fetch timestamp (ISO 8601). |

### Coverage — 1,100+ counties/towns across 15 states

Statewide (search by state code): **NC** (100), **TN** (95), **NY** (38), **WI** (72), **MA** (351 munis), **MT** (56), **WA** (~39), **MD** (24), **CO** (44), **WY** (23), **ND** (~53), **CT** (169 towns).
Per-county: **Cook County, IL** (Chicago — search with county = `Cook`), **UT** (29 counties, by name), **MS** (28 counties, by name or Delta code).

#### Cook County, IL (Chicago)

Sourced from the Cook County Assessor's official open-data rolls (parcel
addresses + assessed values). Values are the Assessor's **assessed values**
(the most-final tier available per year: Board of Review > certified >
mailed). Note Cook County assesses residential property at **10% of market
value** and most commercial at 25% — multiply accordingly when comparing to
market prices.

#### Mississippi counties (28)

**North Carolina** — all 100 counties, statewide (search with county = `NC`).

**Mississippi (28 counties)** — search by county name or Delta code:

Alcorn, Clarke, Forrest, George, Greene, Jasper, Jones, Lafayette, Lamar,
Lauderdale, Lee, Lincoln, Lowndes, Marion, Marshall, Neshoba, Newton, Noxubee,
Pearl River, Perry, Pike, Scott, Stone, Tippah, Union, Warren, Washington, Wayne.

More Mississippi counties on the same platform can be added on request. Other
state/vendor sources (Socrata open-data counties, county GIS portals) are on the
expansion roadmap.

### Notes

- Data is fetched live from the official county roll on each run.
- Value fields reflect what the county publishes; some parcels publish only a
  total (land/improvement split may be `null`).
- Estimates/records only — verify against the county assessor for any decision.

echo '{

{
    "mcpServers": {

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).
