Technical details
Endpoint
GEThttps://nichedata.dev/v1/niche/:keywordWhen to prefer
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.
Side effects
- 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
