The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

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. 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 ## Maven Central Scraper — Java Package & Artifact Extractor Extract Java package metadata from the Maven Central Repository via its public Solr API. Search by keyword, group ID, or artifact ID to retrieve artifact details, versions, timestamps, packaging info, and tags. Ideal for dependency analysis, security auditing, and Java ecosystem research. ### Use Cases - **Dependency Research** — Find artifacts by group ID or artifact ID for build tool configuration - **Security Auditing** — Extract version counts and publication dates to identify outdated dependencies - **Ecosystem Analysis** — Batch-search Maven Central to map Java library trends and popularity - **License Compliance** — Gather artifact metadata for open-source compliance reporting ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `searchQueries` | Array | No | Search terms to query Maven Central (e.g., `["gson", "junit"]`). Each term returns up to `maxResults` artifacts. | | `groupId` | String | No | Exact Maven groupId to filter by (e.g., `com.google.code.gson`). | | `artifactId` | String | No | Exact Maven artifactId to filter by (e.g., `gson`). | | `includeAllVersions` | Boolean | No | If `true`, fetches all published versions for each artifact. Default: `false`. | | `maxResults` | Integer | No | Maximum artifacts per query (1–1000). Default: `100`. | | `proxyConfiguration` | Object | No | Proxy settings for requests. Built-in proxy support included by default. | ### Output The Actor outputs a dataset with the following fields: ```json { "groupId": "com.google.code.gson", "artifactId": "gson", "latestVersion": "2.14.0", "version": "2.14.0", "packaging": "jar", "repositoryId": "central", "versionCount": 44, "timestamp": 1776970907000, "publishedAt": "2026-05-10T12:21:47.000Z", "tags": ["library", "json", "gson"], "searchQuery": "gson" } ```` When `includeAllVersions` is enabled, each version becomes a separate row with its own `version` and `publishedAt` fields. ### Pricing Pay per event: **$0.002 per artifact scraped**. Charging is applied after each batch of results. The Actor respects spending limits and stops gracefully when the limit is reached. ### Limitations - Maven Central API has no documented rate limits, but excessive volume may trigger throttling. Use reasonable `maxResults` values. - The API returns only artifacts published to Maven Central. Private repositories or other hosts (JCenter, GitHub Packages) are not covered. - `includeAllVersions` generates additional API calls. Large artifact histories may increase run time. ### FAQ **Q: Do I need a Maven Central API key?** A: No. This Actor uses the public Solr search endpoint which requires no authentication. **Q: Can I search by partial artifact name?** A: Yes. Use `searchQueries` with partial names. The Actor queries Maven Central's search index which supports partial matching. **Q: What is the difference between `latestVersion` and `version`?** A: `latestVersion` is the most recent version known for the artifact. `version` is the specific version of that row. When `includeAllVersions` is disabled, they are identical. **Q: How do I find all artifacts in a group?** A: Set `groupId` to the exact group (e.g., `org.apache.commons`) and leave `searchQueries` empty. ### Changelog - **v1.0.0** — Initial release. Search by query, groupId, or artifactId. Optional full version history. # Actor input Schema ## `searchQueries` (type: `array`): List of search terms to query Maven Central (e.g., gson, junit, spring) ## `groupId` (type: `string`): Exact Maven groupId to filter by (optional, e.g., com.google.code.gson) ## `artifactId` (type: `string`): Exact Maven artifactId to filter by (optional, e.g., gson) ## `includeAllVersions` (type: `boolean`): If true, fetches all published versions for each artifact.
