## 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.md):

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

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

## USDA Plant Hardiness Zone Lookup (by ZIP Code)

Resolves US ZIP codes to USDA 2023 Plant Hardiness Zones via [phzmapi.org](https://phzmapi.org). Run once to build the full ~33,700-ZIP lookup table, or supply a custom ZIP list for on-demand lookups.

### What it does

The [USDA Plant Hardiness Zone Map](https://planthardiness.ars.usda.gov) is the standard reference for where plants can survive winter temperatures across the US. This actor scrapes zone data for every US ZIP Code Tabulation Area (ZCTA) from the community-maintained JSON API at phzmapi.org, which wraps the official 2023 USDA raster.

**Key features:**

- **Full table mode** — run with no input to scrape all ~33,700 US ZCTAs in one go
- **On-demand mode** — supply a custom list of ZIP codes for targeted lookups
- **Parsed numeric fields** — `zone_number` (7), `zone_half` ("b"), `temp_min_f` / `temp_max_f` integers — ready for database joins and spreadsheet filters
- **Source attribution** — every record carries `source: "USDA PHZM 2023 via phzmapi.org"` for data lineage

### Output fields

| Field | Type | Description |
|-------|------|-------------|
| `zipcode` | string | 5-digit US ZIP code (zero-padded) |
| `zone` | string | USDA 2023 hardiness zone, e.g. `"7b"` |
| `zone_number` | integer | Numeric part of the zone, e.g. `7` |
| `zone_half` | string | Half-zone suffix: `"a"` or `"b"` |
| `temperature_range_f` | string | Avg annual extreme minimum temp range, e.g. `"5 to 10"` |
| `temp_min_f` | integer | Lower bound in °F |
| `temp_max_f` | integer | Upper bound in °F |
| `latitude` | number | ZCTA centroid latitude |
| `longitude` | number | ZCTA centroid longitude |
| `source` | string | Data attribution string |
| `coverage_note` | string | Populated only when a ZIP has no PHZM coverage |

### Sample output

```json
{
  "zipcode": "90210",
  "zone": "10b",
  "zone_number": 10,
  "zone_half": "b",
  "temperature_range_f": "35 to 40",
  "temp_min_f": 35,
  "temp_max_f": 40,
  "latitude": 34.088808,
  "longitude": -118.40612,
  "source": "USDA PHZM 2023 via phzmapi.org",
  "coverage_note": null
}
````

### Input

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `zipcodes` | array | No | List of 5-digit US ZIP codes to look up. Leave empty to fetch the full US ZCTA universe (~33,700 records). |
| `maxItems` | integer | No | Maximum records to return. Useful to cap a full-table run for testing. |

**Example — lookup a handful of ZIP codes:**

```json
{
  "zipcodes": ["90210", "10001", "60601", "98101"]
}
```

**Example — full US table (no input needed):**

```json
{}
```

### Use cases

- **Garden-planner apps** — resolve user's ZIP to hardiness zone at signup
- **Seed & nursery e-commerce** — filter plant catalog by customer's zone
- **Landscaping / agronomy SaaS** — embed the full table as a reference dataset
- **AI agents** — deterministic zone lookup without a live API call at inference time
- **Climate dashboards** — correlate hardiness zones with weather or crop data

### Notes

- Data source: [phzmapi.org](https://phzmapi.org) (community JSON wrapper of the USDA 2023 Plant Hardiness Zone Map raster)
- Zone data changes only when USDA revises the map (last revision: 2023). A full-table refresh is needed only after official USDA updates.
- A small number of ZIP codes (military addresses, PO box-only ZIPs) have no PHZM coverage. These ZIPs produce 0 records.
- Bundled ZIP list source: US Census Bureau 2023 ZCTA Gazetteer (33,791 ZCTAs).
