# Score KDP book niches by BSR, reviews and competition

**Use case:** 

Give your book niche ideas and get, for each one, the top amazon.com books with Best Sellers Rank, price, rating, reviews, publication date, pages and the Independently published (KDP) flag, plus a 0-100 niche score from the median BSR and the median review count of the top 10. Compare niches side by side before you write. Replace the sample keywords with yours.

## FAQ

### How do I check if a KDP book niche is worth entering?

Put your niche phrases in keywords. Each gets a niche row with nicheScore, a verdict (promising, mixed, saturated or low-demand), demandScore and competitionOpennessScore, from the top 10 organic books.

### Does it estimate sales or royalties?

No. Only numbers Amazon shows publicly are used, such as Best Sellers Rank, reviews, price and publication date. It does not turn BSR into a sales estimate, which would be a guess.

### How do I switch between the Books store and Kindle?

Set format to books (all formats) or kindle (the Kindle Store). booksPerKeyword sets how many organic books are read per keyword, and includeSponsored adds ad slots flagged sponsored.

### What does detailStatus mean on a book row?

It says whether the book's own page was read. With includeDetails on you get BSR, publisher and print length. Statuses like refused, time or not-found mean the page was not read, and those rows are delivered free.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/tagadanar/kdp-niche-analyzer.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
