Seasonality is the whole game in Amazon research, and a 7-day series over an arbitrary range answers it directly. Share of voice is the other genuinely hard number — knowing which brands own the first pages for a keyword is what tells you whether a category is enterable. That all of this answered without credentials is worth noting and worth not relying on: an open endpoint today is a rate-limited one tomorrow.
Jungle Scout's endpoint, which answered our probe as js-mcp 1.0.0 — and unusually, tool calls succeeded without credentials as well as the listing.
- keywordsByAsinQuery — the keywords an ASIN ranks for, with volume filters
- keywordsByKeywordQuery — related keywords with data, filtered by search volume
- keywordsHistoricalSearchVolumeQuery — exact-keyword volume in 7-day increments over a date range
- productDatabaseQuery — the product database filtered by ASIN, brand, category and keyword exclusions
- salesEstimatesForAsinQuery — price and sales estimates for an ASIN over a period
- shareOfVoiceQuery — the share each brand controls on the first pages of a keyword search
None that we encountered.
