## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Tribal Land Jurisdiction Screener — Reservation, Trust Land & THPO Check

**Tribal land jurisdiction API.** Give it a batch of coordinates and it runs a
server-side point-in-polygon check against the U.S. Census Bureau's American
Indian, Alaska Native, and Native Hawaiian Areas (AIANNH) boundaries and returns,
per point, whether it falls on **tribal land** — plus the area name and type, the
land area, and ready-to-use flags for **Section 106 THPO consultation**,
**civil/regulatory jurisdiction**, and **trust-land lending/title** review.

The transform is the value: raw Census/USGS layers give you a polygon dump. This
actor normalizes the feature-type codes, separates *legal reservation/trust land*
from *Census statistical areas*, and emits one clean, chainable row per asset.

### Who it's for
- **Section 106 / cultural-resource consultants** — flag when a project site sits
  on tribal land so review routes through the **Tribal Historic Preservation
  Office (THPO)** instead of the SHPO.
- **GovCon, energy & infrastructure siting** — screen candidate sites (towers,
  pipelines, solar/wind, ROW) for tribal jurisdiction before diligence.
- **Gaming / land-into-trust / economic development** — confirm reservation or
  off-reservation trust status.
- **Lenders, title & real-estate diligence** — trust and restricted-fee land has
  distinct foreclosure, mortgage, leasehold and title rules (BIA-approved leases,
  HUD Section 184).
- **AI agents** — a clean geospatial tool for "is this coordinate on tribal land,
  and what regimes apply?"

### Example input
```json
{
  "assets": [
    { "lat": 36.07, "lon": -109.55, "label": "Navajo Nation, AZ" },
    { "lat": 32.7791, "lon": -96.8, "label": "Downtown Dallas TX" }
  ],
  "maxAssets": 500
}
````

#### Verified sample run

A real 6-site run (2026-07-21) returned 6 rows and 0 errors. Every hit came back as
area type **"Federal American Indian Reservation / Off-Reservation Trust Land"** with
`section106_thpo_consultation: true`:

| Asset | On tribal land | Area name | THPO consultation |
|---|---|---|---|
| Navajo Nation, AZ | true | Navajo Nation | true |
| Pine Ridge Reservation, SD | true | Pine Ridge | true |
| Wind River Reservation, WY | true | Wind River | true |
| Gila River Indian Community, AZ | true | Gila River | true |
| Osage OTSA, OK | true | Osage | true |
| Downtown Dallas, TX (control) | false | — | false |

The control point returned a clean, billable "no tribal jurisdiction" row rather than an
error. This exact run is published as the actor's example task, so you can open it and
re-run it as-is.

### Output fields (one row per asset)

| Field | Meaning |
|---|---|
| `asset_label`, `asset_lat`, `asset_lon` | The screened point, echoed back |
| `on_tribal_land` | True if the point is inside any AIANNH area |
| `area_name` / `area_full_name` | Area name (e.g. Navajo Nation) |
| `area_type_code` / `area_type` | MTFCC code + decoded type (reservation/trust, Hawaiian Home Land, ANVSA, OTSA, SDTSA, TDSA, joint-use) |
| `land_tenure_class` | Reservation / Trust land vs Statistical area vs Alaska Native Corporation |
| `reservation_authority` | Federal or State reservation |
| `geoid`, `aiannh_code`, `aiannh_class_code` | Census identifiers |
| `land_area_sqm` / `land_area_sqmi` | Land area of the area |
| `water_area_sqm` | Water area of the area |
| `centroid_lat` / `centroid_lon` | Centroid of the matched area |
| `is_reservation_or_trust_land` | Legal Indian country (federal reservation / trust / HHL) |
| `is_statistical_area` | Census tabulation geography only — **not** a legal jurisdiction boundary |
| `section106_thpo_consultation` | Any tribal hit → THPO cultural review may apply |
| `civil_regulatory_jurisdiction` | Reservation/trust → distinct tax/permit/gaming/land-into-trust regimes |
| `lending_title_review` | Reservation/trust → distinct foreclosure/mortgage/title rules |
| `overlapping_area_count` | How many AIANNH areas the point falls in |
| `overlapping_areas` | All areas the point falls in |
| `source`, `source_url`, `checked_at`, `disclaimer` | Provenance |

### Data sources (keyless, authoritative)

- **Primary:** U.S. Census Bureau TIGERweb **AIANNHA** MapServer (layer 47) —
  federal & state American Indian reservations, off-reservation trust land,
  Hawaiian Home Lands, and Alaska Native / tribal statistical areas (2025 vintage).
- **Fallback / cross-check:** USGS The National Map **govunits** "Native American
  Area" layer — used automatically if the Census service is unavailable, so a
  source outage still returns a graceful result.

### Use as an MCP tool

This actor is a clean, chainable tool for AI agents (Claude, Cursor, etc.) via
[mcp.apify.com](https://mcp.apify.com). Field-level output descriptions let an
agent call it as a "tribal-land jurisdiction" lookup and pass results downstream
(e.g. into a §106 consultation or siting workflow).

### FAQ

**Is this a legal land-status or jurisdiction determination?** No. It is an
informational intersection screen. Census *statistical areas* (ANVSA/OTSA/SDTSA/
TDSA) approximate tribal areas for tabulation and are **not** legal jurisdiction
boundaries. Always confirm Indian-country status, jurisdiction and title with the
affected Tribe, the BIA, the THPO, and legal counsel.

**How do I check if a coordinate is on an Indian reservation?** Pass it in
`assets` and read `is_reservation_or_trust_land` and `area_type`.

**Does it cover Alaska and Hawaii?** Yes — Alaska Native Village Statistical Areas
and Hawaiian Home Lands are included. (Alaska Native Regional Corporations are a
separate Census layer and are decoded if present.)

**How is it billed?** One result row per screened asset (Pay-Per-Event). Empty or
invalid inputs cost nothing beyond the tiny actor start.

**What coordinate system?** WGS84 decimal degrees (`lat`, `lon`).

### Related screeners
