Three things go by the name "Amazon API" and they solve different problems. What each one can and cannot return, and the most common misjudgement: expecting SP-API to show you a competitor.
What Amazon sales data can and cannot tell you: the API labels its own estimates
The marketplace never publishes unit sales, so every monthly figure is derived from BSR. This breaks down the fields across three sales endpoints — which are facts, which are derived, and the parent-versus-child comparison that quietly inflates results.
Four hidden costs of building your own Amazon scraper
Getting a scraper running is a day-one problem. This breaks down the four recurring costs that start after: anti-bot upkeep, defining your own field semantics, compliance exposure, and what happens when the person who wrote it leaves.
