A Social Blade alternative for developers
If you want follower, view, and post counts for creators in your own code, Captapi returns them as JSON from YouTube, TikTok, Instagram, X, and Twitch with one API key. Social Blade is better if you want ready-made charts with long history.

Endpoints that cover this job
What Captapi does not do here
- No charts or rankings pages. You get numbers, and you draw the chart.
- No backfilled history. The series starts at the first fresh fetch.
- Some counts are null when the platform does not show them. For example, Instagram following and post count can be null.

Frequently asked questions
Does Captapi have historical follower data like Social Blade?+
Only from the first time an account is fetched fresh through Captapi. GET /v1/history returns those stored points. It cannot show data from before that.
Which platforms are covered?+
Profile stats from YouTube, TikTok, Instagram, X, and Twitch, each through its own endpoint.
Why are some counts null?+
When a platform does not show a number publicly, Captapi returns null instead of guessing. YouTube subscriber counts are rounded by YouTube, and followersIsApproximate says so.
