Rainforest API is the gold standard for deep Amazon data (reviews, search results, historical pricing). PriceFetch is cheaper, simpler, and supports multiple retailers if you just need current prices.
Rainforest API and PriceFetch solve overlapping but different problems. Rainforest API is a mature, Amazon-focused data platform that gives you access to product details, reviews, search results, seller information, and pricing — essentially the entire Amazon catalog as an API. It has been around for years and has a well-deserved reputation for reliability.
PriceFetch takes a different approach. Instead of going deep on one retailer, it goes wide across multiple retailers with a deliberately simple API surface. You send a product URL, you get back the current price. No pagination, no complex query parameters, no 50-field response objects.
The right choice depends entirely on what you are building. If your product lives and dies by Amazon data, Rainforest is hard to beat. If you need prices from Amazon, Walmart, Target, and others through a single integration, PriceFetch is the more practical option.
Rainforest API pricing starts at $49/month for 5,000 requests, working out to roughly $0.01 per request. Higher tiers reduce the per-request cost, but even at scale you are looking at $0.005+ per call. This is reasonable given the depth of data you get back — a single Rainforest request can return product details, pricing, Buy Box info, and more.
PriceFetch uses a credit-based model. You get 500 free credits on signup (one credit per successful request), and credit packs start lower per request than Rainforest. Failed requests due to server errors do not consume credits. The credit model means you pay for what you use without committing to a monthly minimum.
For teams making fewer than 5,000 requests per month, PriceFetch is meaningfully cheaper. At high volume (50,000+ requests), the gap narrows. Rainforest's enterprise tiers include dedicated support and SLAs that PriceFetch does not yet offer.
Neither API charges for failed requests caused by their infrastructure — a fair policy on both sides.
Rainforest API uses a parameter-heavy request model. You specify the Amazon domain, ASIN or search term, and the type of data you want (product, search, reviews, offers). The response is comprehensive — often 100+ fields per product. This is powerful but means you will spend time parsing the response to extract the fields you actually need.
PriceFetch has one endpoint. You pass a product URL, you get back price, currency, stock status, and retailer name. The response is a flat JSON object. There is no pagination, no request type parameter, no domain parameter — the URL itself encodes all of that information.

# PriceFetch
curl -H "X-API-Key: pf_live_abc123" "https://api.pricefetch.dev/v1/price?url=https://amazon.com/dp/B0TEST"Rainforest API is Amazon-only. It covers all Amazon country domains (US, UK, DE, JP, etc.) and provides deep data for each: product details, search results, reviews, Best Sellers, deals, and more. If Amazon is your only data source, Rainforest covers every angle.
PriceFetch supports Amazon (all major country domains), Walmart, Target, eBay, Best Buy, Newegg, iHerb, and is actively adding more retailers. The trade-off is clear: PriceFetch covers more retailers but returns less data per retailer. You get the current price and stock status, not reviews or search rankings.
If you are building a price comparison tool that spans multiple retailers, PriceFetch saves you from integrating with 5+ different APIs or maintaining your own scrapers. If you are building an Amazon analytics tool, Rainforest gives you the depth you need.
Both APIs return real-time data. Rainforest API makes live requests to Amazon when you call their API — no stale cache. PriceFetch also does live scraping on every request using headless browsers.
Rainforest has an edge here: their infrastructure is specifically optimized for Amazon, meaning they handle Amazon's anti-bot measures better and have higher success rates on Amazon specifically. PriceFetch handles Amazon well but its success rate may be slightly lower on edge cases like geo-restricted products or rapidly changing prices.
Rainforest also offers a historical data endpoint that lets you query past prices — something PriceFetch does not provide. If you need to show price trends over time, you will need to store PriceFetch responses yourself and build the historical view.
Choose Rainforest API if: you only need Amazon data, you need deep product information beyond pricing (reviews, search rankings, seller data), you need historical price data, or you need enterprise SLAs and dedicated support.
Choose PriceFetch if: you need prices from multiple retailers through a single API, you want a simpler integration with fewer response fields to parse, you want lower per-request costs for basic pricing data, or you are building a price comparison tool that spans beyond Amazon.
Both are solid options. Rainforest has years of maturity and Amazon-specific depth. PriceFetch trades that depth for breadth and simplicity. For many use cases — deal trackers, price monitors, competitive intelligence across retailers — PriceFetch's approach is more practical and cost-effective.
Choose Rainforest API if you need deep Amazon-specific data like reviews, search rankings, or historical pricing. Choose PriceFetch if you need real-time prices across multiple retailers with a simpler API and lower cost per request.
