FAQ

Frequently asked questions

The TagX Social Listening API collects public data from Instagram, TikTok, Twitter/X, YouTube, Reddit, Facebook, and LinkedIn, plus 20+ major social platforms overall. For each source you can pull posts, Reels and short-form video, stories, threads, comments, hashtags, creator and brand profiles, and engagement metrics. If you need a platform or region not listed, request a free feasibility check and we confirm coverage before you commit.

You can extract post text and captions, hashtags, author mentions, post type, timestamps, language, and geo-tags from each public post. Engagement fields include likes, shares, comments, saves, native reposts, video views, watch time, and completion rate. Author-level fields cover profile bio, follower and following counts, verified status, account category, and audience demographics such as age, gender, and region.

You can consume the data through a REST API or receive it as bulk files in JSON, CSV, Parquet, or NDJSON. TagX delivers to CSV, JSON, Google Sheets, cloud storage, or straight into S3, GCS, Azure, BigQuery, Snowflake, Redshift, or your own warehouse. Managed DaaS pipelines handle extraction, anti-bot and JS rendering, QA, and scheduled or near real-time delivery, so you integrate clean records instead of maintaining scrapers.

Yes. The TagX Social Listening API supports scheduled or near real-time collection so you can track brand mentions, trending hashtags, and engagement spikes as they happen. You set the cadence per feed, and historical backfill is available when you need to reconstruct past conversations for benchmarking or crisis review. This lets monitoring, alerting, and anomaly-detection workflows run on fresh data.

The API provides both: a /v1/sentiment endpoint returns a positive, neutral, or negative label and a numeric sentiment score alongside the structured post, comment, and engagement data. Because every record is delivered as clean JSON, you can also run your own NLP, topic modeling, or scoring models on top of the raw text. Sentiment classification is a signal to combine with your analysis, not a replacement for it.

TagX is a developer-first social data API you can start using in minutes with a self-serve API key, with no enterprise procurement or annual contract required. Compared to Vetric and Socialgist, TagX delivers clean, structured JSON rather than fragile scrapers or legacy feeds, uses native platform relevance ranking for search, exposes full engagement metrics like plays, likes, saves, and reposts, and offers a managed DaaS option with QA and warehouse delivery. Free sample datasets let you validate before buying. Docs: https://listenx.tagxdata.com/docs.
