How to scrape TikTok Comments with Go

Comments on a TikTok video, most liked first. This tutorial gets it with a short Go program and the TikTok Comments 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")
	var items []any
	for {
		req, _ := http.NewRequest("GET", "https://scrapeio.com/v1/tiktok/video/comments"+"?"+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))
		}
		var body struct {
			Data struct {
				Items   []any  `json:"items"`
				Cursor  string `json:"cursor"`
				HasMore bool   `json:"has_more"`
			} `json:"data"`
		}
		json.NewDecoder(res.Body).Decode(&body)
		res.Body.Close()
		items = append(items, body.Data.Items...)
		if !body.Data.HasMore || body.Data.Cursor == "" || len(items) >= 100 {
			break
		}
		params.Set("cursor", body.Data.Cursor)
	}
	fmt.Println(len(items), "items")
	out, _ := json.MarshalIndent(items[:min(3, len(items))], "", "  ")
	fmt.Println(string(out))
}

The loop follows data.cursor until data.has_more is false, and stops at 100 items. Each page is one call, so it costs 1 credit.

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.
`cursor`	string	Cursor from the previous page's data.cursor.

Errors and what you pay

Status	Meaning	Charged
`200`	Success	Yes, unless cached
`400`	A parameter is missing or wrong	No
`401`	The key is missing or invalid	No
`402`	Not enough credits	No
`403`	The account or post is private	No
`404`	Not found on the platform	No
`429`	More than 300 requests a minute	No
`502`	Every source is down; retry shortly	No

Same endpoint in other languages

Prefer no code?

Connect the MCP server to Claude Code, Cursor or Codex and ask in plain English. The agent uses the tiktok_comments tool for you.
