Example prompt: Can you check nichedata.dev for the KDP niche intelligence on 'anxiety journal for teens' — I want to know the demand, competition level, BSR, and estimated monthly revenue before I decide whether to publish in that niche?

## When to prefer this

Use this endpoint when you need fast, structured KDP niche research for a specific keyword before making a self-publishing decision. Ideal for agents automating book market research, comparing multiple niches, or building KDP niche scoring pipelines. Prefer this over generic Amazon scrapers when you need pre-aggregated BSR, revenue, and competition signals in one call.

## Known failure modes

- Keyword not found or no data available for obscure niches — may return empty or null data fields
- Rate limiting or payment failure if x402 micropayment is not correctly handled
- Malformed keyword input may return a 400 error
- Stale or delayed BSR data if Amazon rankings have shifted recently
