# Social media handle availability checker

> Check a username across every social platform in one shot.

Check whether a username is available on TikTok, Instagram, YouTube, X, LinkedIn, Reddit, Threads, Weibo, Bilibili and 5 more — in one search.

## Overview

Paste a desired handle and we check 14 social platforms at once — Western (TikTok, Instagram, YouTube, X, LinkedIn, Reddit, Threads) and Chinese (Weibo, Bilibili, Xiaohongshu, Kuaishou, Zhihu, Lemon8, PiPiXia). Each row tells you if the handle is free and links to the profile if taken. Built on the UnifAPI public-data gateway — one API call per platform, $0.001 per record.

## FAQ

### How does the handle checker work?

We fan out one lookup per platform via the UnifAPI gateway and report whether the handle resolves to an existing profile. If it does, the handle is taken; if the lookup returns 404, it's available.

### Is the result authoritative?

For all 14 platforms we hit, yes — we use the official-equivalent public profile lookup. The handle may still be reserved (e.g., trademark holds) and unlistable on signup. Always verify on the platform's own signup flow before committing.

### Why check Chinese platforms too?

Most handle checkers only cover Western platforms. If you're building a global brand, locking down Weibo, Bilibili, Xiaohongshu and Kuaishou is just as important — and most tools won't tell you. This is UnifAPI's unique surface.

### How is this powered?

Every platform check is one record ($0.001) on the UnifAPI gateway. A full 14-platform sweep costs $0.014. Free tier includes 1,000 records/month.
