<b>Keepa API vs Zinc/Rainforest for live Amazon prices</b>

Review sites with stale prices lose trust and conversions.

<b>Keepa API</b>
Pros:
— Deepest price history, sales-rank graphs, token-based pricing
— One call returns months of price/buybox data
Cons:
— Token economics are confusing; heavy history pulls drain fast
— Not an official Amazon source, ToS-gray for some uses

<b>Rainforest API (and similar SERP-scrape APIs)</b>
Pros:
— Clean JSON of the live product page, including current offers
— No token math, straightforward per-request pricing
Cons:
— Snapshot only, no historical depth
— Per-request cost adds up if you refresh thousands of SKUs hourly

<b>For:</b> Keepa if your angle is price-history charts and 'is this deal real' content. Rainforest-style if you just need accurate current price/availability on hundreds of pages.

<b>Gotcha nobody mentions:</b> Displaying scraped Amazon prices can violate the Associates Operating Agreement (you're supposed to show 'Price may vary'). The official PA-API is the only compliant price source, and it's rate-limited by your sales.

<b>Bottom line:</b> History story → Keepa. Just-need-current → Rainforest. Compliance story → PA-API only.
