## 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

## Google Scholar Case Law Scraper

Search and scrape US court opinions from Google Scholar's case law database. Filter by keywords, courts, and date ranges to collect structured legal data for research, citation analysis, and AI training.

### What it does

This actor searches Google Scholar's case law index and returns structured records for each matching opinion. You supply a search query, optional court filter, and optional date range. The actor paginates through results up to your specified limit, extracting key metadata from each case. Optionally, it can fetch the full opinion text from each case's detail page.

### Use cases

- **Legal research**: Find cases citing a specific doctrine or precedent across all US courts
- **Citation analysis**: Track how many cases cite a landmark opinion over time
- **Legal AI training data**: Collect labeled case text with court, date, and citation metadata
- **Litigation support**: Research how courts in a specific jurisdiction have ruled on an issue
- **Academic research**: Longitudinal studies of judicial trends on constitutional questions

### Input

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query` | string | Yes | Search keywords (e.g. `"fourth amendment search and seizure"`) |
| `court` | string | No | Court filter: `all` (default), `federal` (all federal courts), or `state` (all state courts) |
| `dateStart` | string | No | Start year for date filter (e.g. `"2020"`) |
| `dateEnd` | string | No | End year for date filter (e.g. `"2024"`) |
| `fetchFullText` | boolean | No | Fetch full opinion text from detail pages (default: `false`) |
| `maxItems` | integer | No | Maximum number of results to return (default: `10`) |

**Example input:**

```json
{
  "query": "first amendment freedom of speech public forum",
  "court": "federal",
  "dateStart": "2015",
  "dateEnd": "2024",
  "fetchFullText": false,
  "maxItems": 50
}
````

### Output

Each result record contains:

| Field | Description |
|-------|-------------|
| `case_name` | Full case name (e.g. `"Miranda v. Arizona"`) |
| `citation` | Legal citation extracted from metadata (e.g. `"384 U.S. 436 (1966)"`) |
| `court` | Court that decided the case |
| `date_decided` | Year or date the case was decided |
| `snippet` | Search result excerpt showing relevant passages |
| `full_text` | Full opinion text (only when `fetchFullText: true`) |
| `cited_by_count` | Number of cases citing this opinion |
| `cited_by_url` | Google Scholar URL to the list of citing cases |
| `related_cases_url` | Google Scholar URL to related cases |
| `versions_count` | Number of other sources reporting this case |
| `source` | Source publication from the metadata line |
| `scholar_url` | Direct Google Scholar URL for this case |
| `pdf_url` | PDF URL when available |
| `case_id` | Google Scholar internal case ID |

**Example output record:**

```json
{
  "case_name": "Terry v. Ohio",
  "citation": "392 US 1 (1968)",
  "court": "Supreme Court of the United States",
  "date_decided": "1968",
  "snippet": "...the Fourth Amendment applies to stop and frisk by police officers...",
  "cited_by_count": 18234,
  "cited_by_url": "https://scholar.google.com/scholar?cites=...",
  "scholar_url": "https://scholar.google.com/scholar_case?case=17773605790797706504",
  "case_id": "17773605790797706504",
  "full_text": null
}
```

### Notes

- Results are retrieved from Google Scholar's public case law index. Coverage includes US Supreme Court, federal circuit and district courts, and state appellate courts.
- The `court: "federal"` filter covers all federal courts (Supreme Court, circuit courts, district courts). Use `court: "all"` to include state court opinions.
- Setting `fetchFullText: true` significantly increases run time and resource usage since the actor must load each case's detail page individually.
- Google Scholar does not expose a public API, so this actor uses a real browser to render pages. Each run consumes proportionally more resources than a basic HTML scraper.
- Date filters use year-level granularity only (`YYYY` format).
