Prerequisites

1. API Key

First, you'll need a ScrapeCreators API key to authenticate your requests.

Sign up at app.scrapecreators.com to get your free API key with 100 requests.

2. Development Environment

Make sure you have the following installed:

  • • Kotlin and its dependencies
  • • A code editor (VS Code, Sublime, etc.)
  • • Basic understanding of API requests
  • • Command line interface access

Step 1: Install HTTP Client

OkHttp is an HTTP client for Kotlin/Java

gradle
implementation "com.squareup.okhttp3:okhttp:4.9.3"

Step 2: API Implementation

Now let's make a request to the TikTok API using Kotlin. Replace YOUR_API_KEY with your actual API key.

Kotlin
import java.net.http.HttpClient
import java.net.http.HttpRequest
import java.net.http.HttpResponse
import java.net.URI
import java.net.URLEncoder
import java.nio.charset.StandardCharsets

class Scraper {
companion object {
private const val API_KEY = "YOUR_API_KEY"
private const val BASE_URL = "https://api.scrapecreators.com"
private const val ENDPOINT_PATH = "/v1/tiktok/search/hashtag"
@JvmStatic
fun main(args: Array<String>) {
try {
val result = scrape()
println("Response: $result")
} catch (e: Exception) {
println("Error: ${e.message}")
}
}
fun scrape(): String {
val client = HttpClient.newHttpClient()
// Build query parameters
val params = mapOf(
"hashtag" to "example_value",
"region" to "US",
"cursor" to "10",
"trim" to "example_value"
)
val queryString = params.entries.joinToString("&") { (key, value) ->
"${key}=${URLEncoder.encode(value, StandardCharsets.UTF_8)}"

Step 3: Testing Your Code

API Parameters

This endpoint accepts the following parameters:

hashtagRequired(string)

Hashtag to search for (without #)

regionOptional(string)

Region the proxy will be set to. Note: this isn't going to grab you all tiktoks from this region, you're just setting the proxy there.

Example: US

cursorOptional(number)

Cursor to get more videos. Get 'cursor' from previous response.

Example: 10

trimOptional(boolean)

Set to true to get a trimmed response

Run Your Code

Execute your script to test the API connection. You should see a JSON response with TikTok hashtags data.

✅ Success: You should receive a structured JSON response containing the requested data.

Expected Response

Here's an example of the JSON response you'll receive:

Verify Response Structure

Check that your response includes the expected fields:

  • ✓aweme_list(object)
  • ✓cursor(number)
  • ✓extra(object)
  • ✓has_more(number)
  • ✓log_pb(object)
  • ... and 2 more fields

Best Practices

1

Error Handling

Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.

2

Caching

Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.

3

Security

Never expose your API key in client-side code. Use environment variables and secure key management practices.

Performance Tips

Batch Requests

When scraping multiple hashtags, consider batching requests to maximize throughput while staying within rate limits.

Async Processing

Use asynchronous processing in Kotlin to handle multiple requests concurrently and improve overall performance.

Common Use Cases

Market Research

Analyze TikTok hashtags to understand market trends, competitor analysis, and audience insights.

Content Analytics

Track performance metrics, engagement rates, and content trends across TikTok hashtags.

Lead Generation

Identify potential customers and business opportunities throughTikTok data analysis.

Troubleshooting

Common Errors

401 Unauthorized

Check your API key is correct and properly formatted in the x-api-key header.

402 Payment Required

You ran out of credits and need to buy more.

404 Not Found

The resource might not exist or be private.

500 Server Error

Temporary server issue. Implement retry logic with exponential backoff.
