Social Media API Data Service
Covering 500,000+ channels, get real-time social media monitoring data via RESTful API500,000+ Channels Covered — Access Real-Time Social Media Data via RESTful API
LargitData Social Media API provides a unified RESTful interface, enabling developers and data analysts to access social media data in real time from over 500,000 channels — including Weibo, Xiaohongshu, Douyin, Facebook, Instagram, Twitter (X), YouTube, PTT, and Dcard — via standard HTTP requests. All returned data is in standard JSON format, containing structured fields such as post content, publish time, interaction metrics (likes, comments, shares), and author information, ready for direct import into your data analysis pipeline.
The service uses a monthly subscription model with flexible billing based on API call volume and data scope — no long-term contracts required. We provide comprehensive API documentation and technical support, with multi-dimensional query filtering by keyword, time range, platform, language, and more. If existing data sources cannot meet your needs, we can custom-add data crawling for specific websites, forums, or social platforms to ensure the most complete sentiment data coverage.

500,000+ Channel Coverage
Data sources cover Taiwan's domestic communities (PTT, Dcard, Mobile01), Chinese platforms (Weibo, Xiaohongshu, Douyin, Baidu), and global social media (Facebook, Instagram, X, YouTube, Reddit). New channels are continuously added and updated daily to ensure data coverage meets the completeness requirements of market research and sentiment monitoring.
Customizable Data Sources
For monitoring specific industry forums, vertical communities, local news sites, or competitor official channels, we can custom-add data sources based on your requirements. From requirements confirmation to data going live, we provide a complete technical integration process to ensure your data precisely covers the target market and audience, capturing every critical sentiment signal.
24/7 High-Availability Service
The API service is deployed on a high-availability cloud architecture, providing 24-hour uninterrupted access. The system features auto-scaling capabilities to maintain stable response speeds even during query surges caused by breaking events. A real-time service status page ensures API availability never disrupts your business workflows or data analysis schedules.
Standard RESTful API Interface
Provides clean RESTful API endpoints returning standard JSON data. Supports multi-dimensional queries and filtering by keyword, date range, platform source, language, and other conditions. Comes with comprehensive API documentation and sample code, allowing developers to complete integration quickly and incorporate social data into their own analysis systems, dashboards, or BI tools.
KYC / AML and Compliance Data
Social media data can serve as a supplementary data source for KYC (Know Your Customer) and AML (Anti-Money Laundering) reviews. Query a specific subject's public activity records, public opinion associations, and risk signals on social platforms via API to assist financial institutions and compliance departments with background investigations, risk assessments, and ongoing monitoring.
Real-Time Data Updates
The database continuously crawls the latest content from all social platforms in real time, with latency from post publication to API query availability controlled at the minute level. Combined with a high-efficiency indexing engine, response times remain at the second level even when querying large volumes of historical data. Supports advanced features including paginated queries, sorting, and aggregate statistics for seamless data retrieval and analysis.
