Social Media Data API for Weibo, Xiaohongshu (RedNote), Douyin and Threads

More than an API: we monitor, clean, translate and backfill the data for you and deliver it straight into your systems, with an SLA and data-source documentation. Priced in USD by platform and volume, trial available on request.

LargitData Social Media Data API covers public posts and comments on Weibo, Xiaohongshu, Douyin and Threads. Pull the data yourself through the API, or let us run it for you: we keep monitoring the keywords and accounts you choose, clean them into consistent fields, translate them into English, fill in past data, and deliver everything straight into your systems.

Data is collected by web crawlers from content publicly published on each platform, and we can describe our data sources and collection methods for review by your legal or compliance team. Other sources such as PTT/Dcard, X and Reddit are available through account-configured channels and keyword groups; contact us.

Douyin here means the Chinese Douyin app, which is a separate platform from the international TikTok. For how their data differs, see TikTok vs Douyin: how the data differs.

Four platform APIs

Weibo, Xiaohongshu, Douyin and Threads each have their own API reference page listing endpoints, parameters and a synthetic sample. Other sources such as PTT/Dcard, X and Reddit are provided through the channels and keyword groups configured for your account; contact us.

Async task workflow

Create a search or collection task, poll its status with the task ID, and fetch the JSON result once the status is DONE. Tasks can be created with conditions such as keywords and date ranges.

RESTful JSON API

Responses are standard JSON; send your API key in the auth-header header on every request. Base URL: https://api.infominer.io/api/v2.

Weibo in English

Subscribe to Weibo with English keywords; the system backfills the last 30 days of posts and adds English machine translation. Translated posts, comments and reposts are read through query endpoints.

Custom data sources

If you need to monitor specific industry forums, vertical communities, local news sites or competitors' official channels, we can assess the request and add custom data sources, with technical integration support from requirements to go-live.

KYC / AML data

Financial institutions and compliance teams can collect public posts, comments and public-account timelines as inputs to their own KYC (Know Your Customer) and AML (Anti-Money Laundering) reviews. The API does not score risk; it delivers data, and the review and judgment stay with your team.

Use Weibo data without reading Chinese: when you set up monitoring with English keywords, the system converts them into Chinese and adds common Chinese names, collects posts from the past 30 days and attaches an English machine translation, so search results, comments and reposts can all be read directly.

FAQ

Last updated:

What Is LargitData's Social Media API Service?

The LargitData Social Media Data API is a REST API for public posts and comments from Weibo, Xiaohongshu, Douyin and Threads. You create asynchronous tasks such as keyword search or comment collection, poll their status, and fetch the JSON result when the task is done.

Which Social Media Platforms Are Supported?

We currently cover four platforms, Weibo, Xiaohongshu, Douyin and Threads, each with its own API reference page. Douyin is ByteDance's mainland-China app, separate from TikTok. Other sources such as PTT/Dcard, X and Reddit are provided through the channels and keyword groups configured for your account; contact us.

How does the API deliver data? Is it a real-time stream?

It is not a real-time stream. Collection endpoints are asynchronous tasks: create a task, poll its status, and fetch the result once the status is DONE. A Weibo subscription with English keywords backfills the last 30 days of posts and adds English machine translation.

How is the data collected? Does it comply with platform rules?

LargitData collects content publicly posted on each platform using web crawlers, not through the platforms' official developer APIs. Each platform's terms of service restrict automated collection to different degrees, and whether downstream use of the data (such as republication, long-term retention, analysis involving personal data, or cross-border transfer) is compliant depends on your purpose and jurisdiction and must be assessed by your legal or compliance team. We can provide a description of the data sources and collection methods for that review.

What data fields and types are supported?

Fields vary by platform. Common ones are post text, post time, author, hashtags, engagement counts (likes, comments, shares) and comment text. See each platform page for the exact fields in its synthetic sample and endpoint descriptions.

Can the Social Media API Be Used for Sentiment Monitoring?

Yes, LargitData Social Media API is the core data source for the InfoMiner sentiment analysis platform. You can use the API directly to integrate with your own analysis system, or pair it with InfoMiner for full AI-powered sentiment analysis including sentiment scoring, trend tracking, and anomaly alerts.

Are there usage limits on the API?

Priced in USD by platform and data volume. Usage and quota are confirmed with you during the trial and quotation.

How Do I Get Started with the Social Media API?

Fill in the form on this page to request a trial. We confirm the scope and reply with trial and integration arrangements. You can review endpoints, parameters and response formats in the public API documentation (api.infominer.io/docs) first.
