## 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.

- `userBadges` - User badges
- `userSolved` - Solved problems with percentages
- `userContest` - Contest rating and stats
- `userContestHistory` - Contest participation history
- `userSubmissions` - Recent submissions (max 20)
- `userAcSubmissions` - Recent accepted submissions (max 20)
- `userCalendar` - Submission calendar
- `userHeatmap` - Activity heatmap (year/month/day breakdown)
- `userSkillStats` - Skill tags by category
- `userLanguageStats` - Programming language stats

#### Problem Operations

- `dailyProblem` - Today's daily challenge
- `selectProblem` - Get specific problem by titleSlug
- `problemList` - List problems with filters
- `officialSolution` - Get official solution for a problem

#### Contest Operations

- `allContests` - All LeetCode contests
- `upcomingContests` - Upcoming contests with countdown
- `contestDetail` - Specific contest details
- `contestRanking` - Contest leaderboard

#### Discussion Operations

- `trendingDiscussions` - Trending discussion topics
- `discussTopic` - Get discussion topic details
- `discussComments` - Get discussion comments

### Example Usage

#### Get User Summary

```json
{
  "operation": "userSummary",
  "username": "uwi"
}
```

#### Get Daily Problem

```json
{
  "operation": "dailyProblem"
}
```

#### Get Problem List with Filters

```json
{
  "operation": "problemList",
  "difficulty": "MEDIUM",
  "tags": "array,dynamic-programming",
  "limit": 50
}
```

#### Get Contest Ranking

```json
{
  "operation": "contestRanking",
  "titleSlug": "weekly-contest-350",
  "page": 1
}
```

### Output

Results are saved to the default dataset with this structure:

```json
{
  "operation": "userSummary",
  "success": true,
  "data": { /* LeetCode data */ },
  "timestamp": "2024-01-15T10:30:00.000Z"
}
```

### Limitations

- **Submission limit**: LeetCode's public API limits `userSubmissions` and `userAcSubmissions` to 20 items. Use `userSummary` for aggregate stats.
- **Rate limiting**: Implemented to avoid overloading LeetCode's servers
- **Premium content**: Some content may require LeetCode Premium subscription

### Notes

- Problem content is cleaned and formatted from HTML to readable text
- HTML entities (`\u003C`, `<`, etc.) are properly decoded
- Solutions include video and code playground links
- Heatmaps include daily submission counts organized by year/month/day

### Cost

This Actor uses minimal compute resources as it only makes HTTP requests to LeetCode's GraphQL API.
