API's advantages include checking results in seconds, fast analysis, and finding unusual solutions. All the functions are at your fingertips, from analyzing a single site to scanning involving complex estimates. 

The Main Advantages of Using API for Keyword Research

Keyword research, a cornerstone of effective SEO and content marketing, entails mining and observing specific words and phrases while seeking information through search engines. This intricate process delves into comprehending key facets such as search volume, competition levels, and the relevance of these keywords to your business line.

Pursuing the perfect keywords empowers businesses to fine-tune their website content and guides your digital content strategy toward optimal visibility and relevance in the online landscape.

These benefits make API a powerful tool for SEO and keyword research:

  • API can be integrated with other tools for more comprehensive data analysis.
  • There are a lot of training materials on working with functionalities.

How to use Serpstat API in Postman

Let's start with a simple case — the keyword overview showing its volume, CPC, and level of competition. This will be useful, for example, to check a few seed keywords in one go.

1.Go to the Postman API Platform (you can use both cloud or installed software) and follow the instructions on creating an account and installing.
2.Move to the “Workplaces” section:

3.Follow this guide to specify endpoint and request parameters. 
4.Add your secret API key from the Serpstat profile to the endpoint.

5.Copy the request parameters from the method description page.

6.Paste to the Body part in Postman and specify your custom parameters.

You can provide the list of seed keywords, set positions to 20, and specify additional filtering, sorting, and negative keyword options to save your credits and get only relevant results.

This is an example of my request:

    "id": "1",
    "method": "SerpstatKeywordProcedure.getKeywordsInfo",
    "params": {
        "keywords": [
            "steve madden sneakers",
            "steve madden sneakers for women",
            "steve madden shoes",
            "steve madden USA",
            "steve madden buy online"
        "se": "g_us",
        "filters": {
            "cost_from": 0.2,
            "region_queries_count_from": 20,
            "minus_keywords": ["store","high heels", "men"]
7.7. Set POST, and click “Send.”
Set POST, and click “Send”

In case your request was successful, you’ll get similar results. The most common causes of errors are:

1.Syntax error code -32700. Check your JSON request in Body and try again.
    ""id"": null,
    ""error"": {
        ""code"": -32700,
        ""message"": ""Parse error"",
        ""data"": {}
2.Keywords error, 32009, follow the instructions in the error message. These instructions are your guiding light, helping you navigate the troubleshooting process effectively.
"{""id"": ""1"",
    ""error"": {
        ""code"": 32009,
        ""message"": ""Not valid parameter \\'keywords\\'. 
There must be a minimum of 1 items in the array"",
        ""data"": {}

The .getKeywordsInfo method will help you to analyze the difficulty and competition level, as well as the number of results to choose the most effective seed keywords.

How to collect a keyword list in 10 minutes?

While keyword research is often perceived as time-consuming, there are streamlined approaches. Here's a quick guide to effective keyword research:

  • Define your core topic
  • Generate relevant keyword ideas
  • Evaluate search volume and competition
  • Focus on long-tail keywords
  • Continuously monitor and optimize your keyword strategy.

Once step #1 is completed, various methods can be used to generate keyword ideas.

  • Analysis of direct competitors' site
  • Brainstorm, thinking about your target audience or even using ChatGPT
  • Using keyword research tools like Google Keyword Planner or Serpstat.

All these methods are widely applicable and effective; however, they require much time. Therefore, we created a faster way, using the add-on for Google Spread Sheets

1.Collect competitors' keywords. You can do it in several ways:
2.The reports Related Keywords and Search Suggestions might be valuable sources for further keyword ideas. Use this option using high-volume queries right in the “C-row”:
The reports Related Keywords and Search Suggestions
3.After getting the suggestions list, check the proposed keywords' search volume. It will help you ensure its relevance to the final keyword pool. Use the Keyword info report, selecting 100 keywords beforehand (the table cannot handle a larger amount of results.).

4.Now, it’s time to evaluate search volume and competition. As for me, the easiest way to do so is by sorting and moving fitting keywords to a separate table.

The competitiveness gauge indicates the degree of challenge one would face when striving to progress with a particular keyword, with a maximum score of 100%. As more domains incorporate this keyword into their advertising campaigns, the level of competition escalates accordingly. It's important to note that this metric undergoes monthly updates.

It is a valuable indicator, particularly pertinent to E-commerce endeavors, as it illuminates the intensity of competition surrounding specific keywords.

5.One more criterion for good keyword research is a focus on long-tail keywords. Use the “Number of keywords” section to detect ‘low competition’ queries.

While recognizing high-volume and low-competition keywords is crucial, emphasizing relevance is equally vital. Ensure your selected keywords align with your business and resonate with your target audience. Failing to do so could attract visitors who lack interest in your products or services.

The final touch is Clustering, which helps distribute topic clusters we might use on a website. This feature will also support you in further optimizing your keyword strategy.


Please note that automated clustering may take longer because Serpstat crawlers need to check the top 30 search engine results for each keyword and group your phrases accordingly.

How are the credits spent?

Each month, Serpstat users get a certain number of API results, according to the pricing plan:

Unused credits burn out at the end of the month. You will spend API results lines for using the services driven by API. If you have a 1000-lined report, 1000 API lines will be spent. On the other hand, some advanced features may spend more lines. Use this tutorial to find out credit spending for each API method.

You can check the credits left by using this request in body:

 "id": 1,
 "method": "SerpstatLimitsProcedure.getStats"

Rapid keyword research enables businesses to save time while enjoying the advantages of thorough keyword analysis. Some benefits of swift keyword research encompass:

Serpstat API is a convenient solution to process vast amounts of data in seconds, which makes it an ideal option for fast keyword research. I hope this use case was insightful and easy to implement. I wish you all the best in your SEO endeavors.
