# Username Availability Checker (`sync-network/username-availability-checker`) Actor Check if usernames are available or taken across 36 platforms (GitHub, Instagram, TikTok, Reddit, YouTube, Twitch, Spotify, and more). Uses fast API endpoint probing — no browser needed. Supports bulk username checking with configurable concurrency and rate-limit handling. - **URL**: https://apify.com/sync-network/username-availability-checker.md - **Developed by:** [Alam](https://apify.com/sync-network) (community) - **Categories:** Developer tools, Automation, Social media - **Stats:** 1 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $0.50 / 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.

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 ## Username Availability Checker Instantly check if a username is available or taken across **36 platforms**. Uses fast API/HTTP probing — no browser required, dirt cheap to run. ### Why? - **Brand protection** — secure your username across platforms before someone else does - **Domain investors** — find valuable available usernames - **Social media managers** — check client name availability at scale - **Security researchers** — detect impersonation or squatting ### Features - **36 platforms** — GitHub, Instagram, TikTok, Reddit, YouTube, Spotify, Twitch, GitLab, Roblox, Chess.com, and more - **API-first** — uses platform APIs (GitHub, Reddit, Hacker News, Mojang, Chess.com, Lichess, Codeberg, Roblox) for reliable results - **Bulk checking** — check multiple usernames at once - **Selective platforms** — check all platforms or pick specific ones - **Fast & cheap** — HTTP probing only, no browser overhead (~$0.00004 per result) - **Concurrent** — configurable concurrency for speed - **Rate-limit friendly** — adjustable delay between requests ### Supported Platforms #### Social Media (14) GitHub, Instagram, TikTok, Reddit, X (Twitter), Threads, YouTube, VK, Tumblr, Snapchat, Mastodon, Pinterest, Spotify, Twitch #### Developer (3) GitLab, Codeberg, Hacker News #### Gaming (5) Steam, Steam Group, Minecraft, Chess.com, Roblox, Lichess #### Creative / Other (8) SoundCloud, Letterboxd, Substack, Replit, BuyMeACoffee, Linktree, Product Hunt, About.me, Flickr, Last.fm, Patreon, Vimeo > **Note:** Facebook, LinkedIn, Medium, WordPress, Discord, Telegram, and Signal are excluded — they require authentication or are behind Cloudflare, making HTTP-only checking unreliable. ### How to Use #### Input | Field | Description | Default | |-------|-------------|---------| | **Usernames** | Comma-separated usernames to check | `example_user` | | **Platforms** | Comma-separated platforms (empty = all) | All 36 | | **Concurrency** | Parallel requests (1–20) | `5` | | **Delay Between Requests** | Seconds between requests | `0.5` | | **Proxy Configuration** | Optional Apify proxy | Off | #### Example: Check one username everywhere ```` usernames: coolbrand2026 ``` #### Example: Check multiple usernames on specific platforms ``` usernames: mybrand, mybrand\_, mybrandofficial platforms: github, instagram, tiktok, twitter, youtube, gitlab, roblox ```` ### Output | Field | Description | |-------|-------------| | `username` | The username checked | | `platform` | Platform display name | | `url` | Profile page URL | | `available` | `true` = available, `false` = taken, `null` = unknown/error | | `error` | Error message if check failed | ### Pricing ~$0.00004 per result in platform costs. Check 5 usernames across all 36 platforms (180 results) for less than a penny. # Actor input Schema ## `usernames` (type: `string`): Comma-separated list of usernames to check (the @ symbol is automatically stripped). ## `platforms` (type: `string`): Comma-separated list of platforms to check.

Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "usernames": "example_user", "platforms": "" }; // Run the Actor and wait for it to finish const run = await client.actor("sync-network/username-availability-checker").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
