Map a market by the things people search

The related topics API returns the subjects Google links to your keyword, each with a type such as brand, company, currency or software. You get a top list and a rising list, about 27 rows in our test. One call costs €0.0015, and 1,000 calls cost €1.50. Other sources and prices are on our all data APIs page. Save a keyword once, and each run's topic list is stored in your Scrapewise account for the table, Excel, your AI assistant or the API.

A topic is a thing, not a phrase. Google groups every spelling and language of a subject into one entry, so the rows show you the market's players without 20 near-duplicate phrasings.

For "bitcoin" in the US on 16 September 2026, the top list included Ethereum (type: Software) at 4 and XRP (type: Currency) at 2. Those are the rivals. The rising list led with Reuters, a news agency, up 2,700%, and Petroleum up 650%. That tells you where the attention came from that month.

Sellers use this to find competitors and neighbors in a category. If you need the exact words to put in a title or an ad, the related queries API is the better fit.

Who maps topics around a keyword

  • Sellers entering a category

    Before you list your first yoga mat, see which mat brands shoppers already connect with the category. That's your competitor list, ranked by attention.

  • Brand owners

    Run your own brand name and see which rival brands sit next to it. A new name in the rising list is a competitor to look up this week.

  • Bundle and cross-sell planners

    Product-type topics that rise with yours are candidates for bundles, add-ons and your next product.

How it works

  1. Enter a category keyword

    Broad works best, like 'protein powder' or your brand name. Keep the US default or set another country code.

  2. Pick the range and schedule

    12 months shows who holds attention, past 7 days shows who's gaining. Schedule it weekly and every run is saved with its date.

  3. Filter by type

    Filter to brand types in the table or Excel, pull rows by API, or ask your AI assistant: 'which brands showed up for protein powder this month that weren't there last month?'

Set it up once. The data keeps coming.

Save your search once and it runs by itself. Every run lands in your own Scrapewise database, and you pick how to read it.

  1. Set it up once

    Add your ASINs, keywords, places or apps to a scraper in the web app. New accounts get 5 free requests.

  2. Runs on your schedule

    Pick daily, weekly on the days you choose, every few days, or the first or last day of the month. Scheduled runs start at night, European time. Need it more often? Start runs from your own code.

  3. Saved in your database

    Each run adds dated rows, so this week sits next to last week. Rows are kept for 90 days.

  4. Use it your way

    Open the table in the web app and download the latest run as an Excel file. Ask your own AI assistant about it. Or pull the rows into your code with an API key.

Ask your AI assistant about your own data

Connect Claude Desktop, Claude Code or another MCP app with a read-only key. The assistant reads the rows you've already collected, at no extra cost on Scrapewise. With a full-access key it can start a run for you too.

  • Which of my ASINs lost the Buy Box this week?
  • Which competitor cut prices the most since Monday?
  • Show the keywords where I dropped out of the top 10.

What you send and what you get back

You send one keyword, and if you like a country and time range. You get top and rising topics, about 27 rows in our test, each with a title, a type, a stable topic ID and a score or growth figure.

What each column means

sw columns appear on every Scrapewise data API. The rest are Google Trends topic fields.

The topic

topic title is the name, like Ethereum. topic type is what Google says it is, like Software, Currency or News agency company. topic value is Google's topic ID, such as /m/05p0rrx for Bitcoin. sw title and sw external id repeat the name and ID, and sw id kind says what kind of ID it is.

  • topic_title
  • topic_type
  • topic_value
  • sw title
  • sw external id
  • sw id kind

Top or rising, and by how much

series is top or rising. On top rows, value is a 0 to 100 score. On rising rows, value is growth like +2,700%, and extracted value is that growth as a number. sw position is the row's place in its list.

  • series
  • value
  • extracted_value
  • sw position

Links

link and sw url open the topic on Google Trends with your country and time range. sw source url opens your keyword.

  • link
  • sw url
  • sw source url

Place, status and time

sw location is the country code, sw status is OK, no results or error, and sw fetched at is the collection time in UTC.

  • sw location
  • sw status
  • sw fetched at

Your request

Your keyword, country, time range and the Trends link, repeated on every row.

  • ctx_search_parameters_q
  • ctx_search_parameters_geo
  • ctx_search_parameters_date

What sellers do with related topics

01

Discover rival brands

Filter the top list to brand and company types. Those are the names shoppers already connect with your category, ranked by how often.

02

Spot new entrants

A brand showing up in the rising list, or jumping up it from one month to the next, usually means a new competitor is getting press or ad spend.

03

Find products to bundle

Product types that rise alongside yours are what the same buyers are shopping for. Test them as bundles or add-ons.

04

Structure keyword research

Use topics as your headings, then run each one through the related queries API to fill it with exact phrases.

05

Track a topic by ID

Each topic has a stable ID, so you can follow one brand across months even if its display name changes.

Why use this API for competitor discovery

  • Things, not spellings

    Google merges the variants, so each brand shows up as one row with its type.

  • Types you can filter

    topic type separates companies from currencies and product types, so a competitor list is one filter away.

  • Cheap to run daily

    Tracking 10 brands every day costs €0.45 a month.

Frequently asked questions

A subject Google recognizes, such as a brand, a company or a product type, with its type shown. One name can appear twice with different types: Reuters came back both as News agency company and as a general topic. Group by topic value to keep them apart.
