## Pricing

from $0.55 / 1,000 gem scrapeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## RubyGems Scraper - Ruby Gems & Downloads

Search **RubyGems** or look up **Ruby gems** by name and get clean rows: **description**, **total and
version downloads**, **latest version**, **licenses**, **authors**, **homepage**, **source code** and
**documentation** links. Built on the official RubyGems API - no API key, no browser, no proxy. Run one
search or import a file of gem names.

### What you get per gem

| Field | Meaning |
|---|---|
| `name` / `version` | Gem name and latest version |
| `downloads` / `versionDownloads` | All-time downloads and downloads of the latest version |
| `info` / `authors` / `licenses` | Description, authors and license list |
| `homepage` / `sourceCode` / `documentation` | Homepage, source repo and docs URLs |
| `bugTracker` / `changelog` / `funding` | Author-declared extra links |
| `versionCreatedAt` / `yanked` / `runtimeDependencies` | Latest-version date, yanked flag and dependency count (on exact `gemNames` lookups) |
| `platform` / `gemUrl` | Platform and the gem's RubyGems page |

### Input

```json
{ "searchQueries": ["authentication", "testing"], "maxItemsPerQuery": 50 }
```

- **Search terms** - one per line (e.g. `rails`, `authentication`, `json`).
- **Gem names** - fetch exact gems (e.g. `rails`, `devise`); these carry the version date, yanked flag and dependency count.
- **Import from a file** - paste a list, or link a public `.txt`/`.csv`, a Google Sheet/Drive link, or an Apify key-value-store record.
- **Output fields** - trim every record to exactly the columns you need.

Leave everything empty and the run returns a small free sample so you can see the shape first.

### Reliability

Reads the **official RubyGems API** - no key, no proxy, no anti-bot. A search that returns nothing, an
unknown gem name, or an import that cannot be read bills **$0** and says why.

### Honest limits

- **`versionCreatedAt`, `yanked` and `runtimeDependencies` are detail-only.** RubyGems returns them on the
  per-gem endpoint, not in search results, so they populate for **`gemNames`** exact lookups and are null
  for **`searchQueries`** results (probed 2026-08-15) - the API's shape, not a scraping gap.
- **`sourceCode` / `documentation` / `bugTracker` / `changelog` / `funding` are author-optional** - present
  only when the gem author declared them; an honest null otherwise.

### Pricing

**$0.001 per gem** on the FREE tier (tiered pricing lowers it with volume). Only gems actually saved are
billed; empty searches, unknown names and unreadable imports cost nothing.

### Output views

- **Gems** - name, version, description, downloads, licenses and source link.

### Use with AI assistants (MCP)

Available through the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp) - an agent can
find the top Ruby gems for a task, compare download counts, or enrich a list of gem names with versions and
licenses in one call.

### Agent-ready: autonomous payments (x402 & Skyfire)

This actor is **agent-ready** - AI agents can discover it, run it, and **pay for it autonomously**, with no Apify account and no human in the loop. It uses [pay-per-event](https://docs.apify.com/platform/actors/publishing/monetize/pay-per-event) pricing and [limited permissions](https://docs.apify.com/platform/actors/development/permissions), so it qualifies for Apify's agentic-payment standards:

- **[x402](https://docs.apify.com/platform/integrations/x402)** - an open, HTTP-native payment protocol. Agents pay per run in USDC on the Base network directly through the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp) - no account, no API key.
- **[Skyfire](https://docs.apify.com/platform/integrations/skyfire)** - agent-to-service payments for fully autonomous AI-agent workflows.

Building an AI agent, MCP tool, or autonomous data pipeline? This scraper is ready to plug in and pay as it goes.

# Actor input Schema

## `searchQueries` (type: `array`):

Terms to search RubyGems for, one per line - e.g. <code>rails</code>, <code>authentication</code>, <code>json</code>. <b>Leave empty and the run returns a small free sample.</b>

## `gemNames` (type: `array`):

Specific gems to fetch exactly, one per line - e.g. <code>rails</code>, <code>devise</code>. These carry the version date, yanked flag and dependency count.

## `searchQueriesFromFile` (type: `string`):

Bulk-load search terms. Either <b>paste the whole list</b> (one per line), or give <b>a single link</b> to a public <code>.txt</code>/<code>.csv</code>, a Google Sheet/Drive link, or an Apify key-value-store record. A file that cannot be read says so and charges nothing.

## `maxItemsPerQuery` (type: `integer`):

How many gems to collect for each search term.

## `maxItems` (type: `integer`):

Overall cap across all searches and names. You are only charged for gems actually saved.

## `outputFields` (type: `array`):

Pick the fields you want and every record is trimmed to exactly those - handy for lean CSV/Sheets exports.

## Actor input object example

```json
{
  "searchQueries": [
    "rails"
  ],
  "maxItemsPerQuery": 50,
  "maxItems": 1000
}
```

# Actor output Schema

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

Each scraped record - a Ruby gem with downloads, version, licenses and source links - as a JSON item in the default dataset.

## CLI example

```bash
echo '{
  "searchQueries": [
    "rails"
  ],
  "searchQueriesFromFile": ""
}' |
apify call scrapesage/rubygems-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,scrapesage/rubygems-scraper"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
