How to scrape TikTok Transcript with Go

Spoken-word transcript of a TikTok video, from its captions. This tutorial gets it with a short Go program and the TikTok Transcript API. Each successful call costs 1 credit; errors and not-found answers are free.

1. Get an API key

Sign in to get a key and 100 free credits, no card. Then put the key in an environment variable so it stays out of your code:

export SCRAPEIO_API_KEY="your_key_here"

2. Set up Go

go mod init scrape

3. Write the code

Save this as main.go. Replace PASTE_URL_HERE with a real url.

package main

import (
	"encoding/json"
	"fmt"
	"net/http"
	"net/url"
	"os"
)

func main() {
	params := url.Values{}
	params.Set("url", "PASTE_URL_HERE")
	req, _ := http.NewRequest("GET", "https://scrapeio.com/v1/tiktok/video/transcript"+"?"+params.Encode(), nil)
	req.Header.Set("x-api-key", os.Getenv("SCRAPEIO_API_KEY"))
	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	if res.StatusCode != 200 {
		panic(fmt.Sprintf("HTTP %d", res.StatusCode))
	}
	defer res.Body.Close()
	var body map[string]any
	json.NewDecoder(res.Body).Decode(&body)
	out, _ := json.MarshalIndent(body["data"], "", "  ")
	fmt.Println(string(out))
}

4. Run it

go run main.go

The response has the same envelope on every endpoint: success, cached, credits_used, credits_remaining and data. Shared fields such as handle, followers, plays, likes and created_at have the same names on every platform.

Parameters

Name	Type	Description
`url` (required)	string	TikTok video URL.
`language`	string	Preferred language code, e.g. en.

Errors and what you pay
