## 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.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## BOEM Offshore Wind Lease Tracker — Inventory & Status Deltas

Track every **active BOEM offshore wind energy lease** on the US Outer Continental
Shelf — lessee, state, acreage, block count, effective and expiration dates — plus
BOEM's **wind planning areas**, straight from the Bureau of Ocean Energy Management's
official ArcGIS layers (Office of Renewable Energy Programs). No API key, no scraping
of protected sites.

The moat is the transform: a **unified, normalized lease inventory** and a built-in
**status delta monitor**. Run it on a schedule in `delta` mode and it diffs the current
inventory against the snapshot from the previous run, emitting only what changed —
new leases (auction results), removed leases, status changes, and acreage changes
(lease segmentations / assignments).

### Who this is for

- **Offshore-wind developers & analysts** — watch competitor lease positions, new
  auction results, and acreage changes without polling BOEM by hand.
- **Marine services & vessel operators** (survey, cable-lay, crew transfer) — a new
  lease or acreage change is a sales trigger; know the lessee and state the day it lands.
- **Energy market & policy analysts** — per-state and per-lessee holdings rollups
  (total acreage, lease counts) saved with every run.
- **GIS teams** — clean lease centroids (WGS84), protraction numbers, and block counts
  ready to join to your own layers.

### Example input

```json
{
  "mode": "inventory",
  "states": ["CA", "New York"],
  "lessee": "RWE",
  "includePlanningAreas": true,
  "maxResults": 500
}
````

Run with **empty input** and you get the full national inventory (~52 active leases +
\~19 planning areas) — bounded, fast, and cheap.

#### Delta mode

```json
{ "mode": "delta" }
```

The first delta run seeds a snapshot in a named key-value store
(`boem-wind-lease-snapshots` by default) and emits 0 rows. Every later run emits one
row per change with `change_type` set to `NEW`, `REMOVED`, `STATUS_CHANGED`, or
`ACREAGE_CHANGED`, plus `previous_status` / `previous_acreage`. Schedule it weekly and
you have a BOEM offshore-wind change feed.

### Output fields (per row)

| Field | Meaning |
|---|---|
| `record_type` | `WIND_LEASE` or `PLANNING_AREA` |
| `lease_number` | BOEM OCS lease number, e.g. `OCS-P 0561` |
| `area_name` | Project name (leases) or planning-area name |
| `lessee` | Company holding the lease |
| `region_or_state` | Adjacent US state (normalized full name) |
| `lease_type` | Commercial / Research / Right of Way, or planning category |
| `lease_status` | `Active` for leases; BOEM `AREA_STATUS` for planning areas |
| `acreage` + `acreage_is_approximate` | BOEM's published acres, or geometry-derived (flagged) |
| `block_count` | OCS blocks/sub-blocks inside the lease |
| `effective_date`, `expiration_date`, `lease_term_years` | Lease dates (`YYYY-MM-DD`); expiration = effective + term |
| `latitude`, `longitude` | Lease centroid (WGS84) |
| `protraction_number`, `project_names` | Cadastral + project context |
| `change_type`, `previous_status`, `previous_acreage` | Delta mode only |
| `source_layer`, `source_url` | Provenance: BOEM layer + lease document / state page |

Per-state and per-lessee **rollups** (lease counts, total acreage) are saved to the
run's key-value store under the `ROLLUP` key on every run.

### Use as an MCP tool

This actor is agent-ready: call it from Claude, Cursor, or any MCP client via
[mcp.apify.com](https://mcp.apify.com). The input and output schemas are fully
described field-by-field, so an AI agent can chain it — e.g. "list active BOEM wind
leases off California, then diff next week" — without human glue code.

### FAQ

**Where does the data come from?** BOEM's official hosted ArcGIS layers (owner
`BOEM_GeoSEAS`, Office of Renewable Energy Programs): *Offshore Wind Lease Outlines*,
*Offshore Wind Planning Area Outlines*, and the block-level *Offshore Wind Leases*
layer. These are the same layers behind BOEM's public renewable-energy maps.

**How current is it?** The layers are maintained by BOEM and updated as leases are
executed, assigned, or segmented. Each run reads them live.

**Why do some acreage values say approximate?** BOEM leaves `ACRES` null on a few
records (e.g. right-of-way grants) and publishes none for planning areas. For those,
acreage is derived from the lease geometry (Web-Mercator area corrected by cos²
of latitude — validated within 0.01% of BOEM's own figures) and flagged with
`acreage_is_approximate: true`.

**What happened to the planning areas?** BOEM rescinded its offshore wind planning
areas on July 30, 2025. The outlines layer is still published with an `AREA_STATUS`
field — this actor keeps tracking it, and delta mode will flag any status flips.

**Is the expiration date official?** It's computed as effective date + published
lease term (e.g. `06/01/2023` + `33 Years` → `2056-06-01`). BOEM does not publish a
per-lease expiration field; treat it as an estimate for lease-management purposes.

**Can I track only my market?** Yes — filter by `states` and/or `lessee`, and give
each filtered universe its own `snapshotStoreName` so deltas stay independent.

# Actor input Schema

## `mode` (type: `string`):

'inventory' emits the current unified wind-lease inventory (one row per lease, plus planning areas). 'delta' compares against the snapshot saved by the previous run in the named key-value store and emits only NEW / REMOVED / STATUS\_CHANGED / ACREAGE\_CHANGED rows. The first delta run seeds the snapshot and emits 0 rows.

## `states` (type: `array`):

Optional filter: only return leases/planning areas offshore of these states. Accepts postal codes (CA, RI) or full names (California). Empty = all states.

## `lessee` (type: `string`):

Optional case-insensitive substring filter on the lessee/company name, e.g. 'RWE' or 'Orsted'. Planning areas have no lessee and are excluded when this filter is set.

## `includePlanningAreas` (type: `boolean`):

Also emit BOEM offshore wind planning-area outlines (record\_type PLANNING\_AREA) alongside active leases. Note: BOEM rescinded its wind planning areas on 2025-07-30; the layer is still published with an AREA\_STATUS field, which this actor tracks for changes.

## `includeBlockCounts` (type: `boolean`):

Count the OCS blocks/sub-blocks inside each lease from BOEM's block-level layer and fill the block\_count field. Adds a few extra API pages per run.

## `snapshotStoreName` (type: `string`):

Name of the Apify key-value store where the lease snapshot is persisted between runs for delta mode. Use different names to track different filtered universes independently.

## `maxResults` (type: `integer`):

Maximum number of dataset rows to emit. The full national inventory is currently ~52 leases + ~19 planning areas, so the default comfortably covers everything.

## Actor input object example

```json
{
  "mode": "inventory",
  "includePlanningAreas": true,
  "includeBlockCounts": true,
  "snapshotStoreName": "boem-wind-lease-snapshots",
  "maxResults": 500
}
```

# Actor output Schema

## `results` (type: `string`):

The default dataset with one row per lease / planning area (inventory) or per change (delta).
