## Pricing

from $2.00 / 1,000 results

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?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## PyPI Package Scraper — Metadata, Deps & Downloads

Look up **Python packages on PyPI** — or discover **newly-added / recently-updated** ones — and get rich, structured metadata: version, summary, **author & maintainer emails**, license, **dependencies**, Python requirement, project links and **download counts**. Clean JSON/CSV/Excel.

**Keyless**, no anti-bot — built for dependency auditing, supply-chain research, package intelligence and **maintainer lead generation**.

***

### What this Actor does

Give it package names (and/or turn on discovery) and for each package it returns:

- **Core** — name, latest version, summary, Python requirement, license, version count.
- **Contacts** — author/maintainer name and **emails** (parsed from PyPI metadata) — great for maintainer outreach.
- **Dependencies** — the full `requires_dist` list and a dependency count.
- **Popularity** — downloads in the last day / week / month (via pypistats).
- **Links** — homepage, project URLs (docs, source, funding…) and the PyPI page.

**Discovery:** optionally pull the newest packages and recently-updated packages straight from PyPI's feeds, each enriched with full metadata.

***

### Why use it

- **Audit your dependencies.** Drop in a `requirements.txt` list and get license, Python requirement, dependencies and maintainer for each — perfect for compliance and supply-chain review.
- **Maintainer lead-gen.** Author/maintainer emails for developer outreach, sponsorships and devrel.
- **Package research & comparison.** Downloads, versions, dependencies and metadata side by side.
- **Track the ecosystem.** Discover brand-new and freshly-updated packages as they land.
- **Keyless and fast.** No API key, no anti-bot — public PyPI + pypistats endpoints.

The Python sibling of an npm package scraper — same dev-tools + lead-gen value, for the PyPI ecosystem.

***

### Who it's for

- **Security & platform teams** auditing dependencies and supply chain.
- **Developer-tool & devrel teams** doing maintainer outreach and ecosystem tracking.
- **Analysts & researchers** studying the Python package ecosystem.
- **Investors & BD** spotting fast-growing packages and projects.

***

### Quick start

#### Run it in the console (no code)

1. In **Package names**, add one per line:

   ```
   requests
   django
   fastapi
   numpy
   ```

2. *(Optional)* enable **Discover recently-updated** or **Discover newest** packages.

3. Keep **Include download counts** on, click **Start**, and export as **JSON, CSV, Excel or HTML**.

Leave everything empty for a **demo**.

#### Run it via API (Python)

```python
from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")

run_input = {
    "packages": ["requests", "django", "fastapi"],
    "includeDownloads": True,
}

run = client.actor("YOUR_USERNAME/pypi-package-scraper").call(run_input=run_input)

for p in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(f"{p['package']} {p['version']} — {p['downloadsLastMonth']}/mo — {p['emails']}")
```

#### Run it via API (JavaScript)

```javascript
import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_APIFY_TOKEN' });

const run = await client.actor('YOUR_USERNAME/pypi-package-scraper').call({
    packages: ['requests'],
    recentlyUpdated: true,
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((p) => console.log(`${p.package}: ${p.dependencyCount} deps, ${p.downloadsLastMonth}/mo`));
```

***

### Input

| Field | Type | Description |
|---|---|---|
| **Package names** | array | PyPI package names, one per line. Empty + no discovery = demo. |
| **Discover recently-updated** | boolean | Pull recently-updated packages from PyPI's RSS feed. |
| **Discover newest** | boolean | Pull brand-new packages from PyPI's RSS feed. |
| **Include download counts** | boolean | Add last day/week/month downloads (pypistats). Default on. |
| **Max packages** | integer | Total cap across list + discovery. Default 200. |
| **Speed (parallel lookups)** | integer | Packages at once. Default 8. |
| **Proxy configuration** | object | Apify Proxy. On by default. |

> **Note on search:** PyPI has no public keyword-search API, so this Actor works by **package name** plus **feed-based discovery** (newest / recently-updated). To audit a project, paste its dependency list directly.

***

### Output

One record per package:

```json

***

### Tips & notes

- **Dependency audit.** Paste a `requirements.txt` package list to get license + Python + deps + maintainer for every one.
- **Emails vary.** PyPI shows author/maintainer emails when the package provides them (~2/3 of packages); the Actor parses them from the metadata.
- **Discovery enrichment.** `recentlyUpdated` / `newestPackages` feed the queue, then each package is fully enriched.
- **Downloads.** Counts come from pypistats; brand-new packages may not have stats yet.
- **Dedupe.** The Actor de-dupes names across your list + discovery automatically.

***

### Frequently asked questions

**Do I need an API key?**
No — public PyPI JSON API + pypistats.

**Can I search PyPI by keyword?**
PyPI has no public keyword-search API. This Actor works by package name plus feed-based discovery (newest / recently-updated). For a project audit, paste its dependency list.

**Does it include download counts?**
Yes — last day/week/month from pypistats (when available).

**Can I get maintainer contacts?**
Yes — author/maintainer emails are parsed from PyPI metadata when present.

**Is this good for supply-chain / security?**
Yes — license, Python requirement, dependencies and version history are exactly what dependency and supply-chain reviews need.

***

### Export & integrate

Results are available as **JSON, CSV, Excel, HTML** and via the **Apify API**. Push to **Google Sheets**, a **webhook**, **Make**, **Zapier** or your database — and **schedule** runs to track packages over time.

```

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).
