ASINSpotlight API vs Rainforest API: Pricing, Features, and Data Quality Compared (2026)
A detailed comparison of ASINSpotlight API and Rainforest API (Traject Data) for Amazon product data scraping. Pricing, request volumes, features, marketplace coverage, and limitations.
If you're building an application that needs Amazon product data — prices, BSR, seller information, reviews — you've probably come across Rainforest API (now part of Traject Data). It's one of the most established Amazon data APIs on the market.
But is it the best option for your budget and use case? In this article, we compare Rainforest API with ASINSpotlight API — a new entrant built on 10 years of Amazon scraping infrastructure.
Pricing Comparison
This is where the difference is most dramatic.
Rainforest API (Traject Data) Pricing
| Plan | Monthly Price | Requests/Month | Cost per Request | Cost per 1K Requests |
|---|---|---|---|---|
| Starter | $59 | 10,000 | $0.0059 | $5.90 |
| Production | $375 | 250,000 | $0.0015 | $1.50 |
| BigData | $1,000 | 1,000,000 | $0.001 | $1.00 |
| Enterprise | Custom | Custom | Custom | Custom |
Annual billing is available with up to 20% discount.
Note that Rainforest API uses credit multipliers for certain parameters. For example, requesting variant_prices, import_fees, or include_safety_product_resources costs 2-3x credits per request. This effectively doubles or triples your actual cost per request when using these features.
ASINSpotlight API Pricing
| Plan | Monthly Price | Requests/Month | Cost per Request | Cost per 1K Requests |
|---|---|---|---|---|
| Early Access | $50 | 100,000 | $0.0005 | $0.50 |
| Higher volume | Contact us | Custom | Custom | Custom |
No credit multipliers — every request costs the same regardless of which data fields you request.
The Cost Difference in Practice
To put this in perspective:
- 100,000 requests on Rainforest API (Starter plan): You'd exhaust the Starter plan in 10K requests ($59), then pay overage at $0.0118/request for the remaining 90K — totaling $1,121/month.
- 100,000 requests on Rainforest API (Production plan): $375/month, with 150K unused requests.
- 100,000 requests on ASINSpotlight API: $50/month.
At the same volume, ASINSpotlight API costs 7-22x less depending on which Rainforest plan you compare against.
Data Quality and Freshness
Both APIs fetch data directly from Amazon in real time — neither relies on a cached database. This is an important distinction from tools like Keepa, which serve data from their own periodically-updated database.
| ASINSpotlight API | Rainforest API | |
|---|---|---|
| Data source | Live from Amazon | Live from Amazon |
| Data freshness | Real-time per request | Real-time per request |
| Data points per product | 60+ fields | Comprehensive (varies by endpoint) |
| Response format | Structured JSON | JSON, CSV, or raw HTML |
Response Time
Rainforest API claims 1-6 second response times in their documentation. However, multiple user reviews on Trustpilot report actual response times of 15-50 seconds for single product requests. One user reported that "customer support tried to convince me that having 30-50 seconds of response time for single listing API request is normal."
ASINSpotlight API is built on the same infrastructure that powers the ASINSpotlight desktop app, which has served millions of requests with consistent sub-5-second response times.
Data Consistency
A recurring complaint in Rainforest API reviews is data inconsistency. One Trustpilot reviewer noted: "Data is wildly inconsistent. Many times the Product API sends back responses that the ASIN has its buybox removed, or no description, or price... and all those things are there on the actual page."
Rainforest API currently holds a 3.1 out of 5 rating on Trustpilot (88 reviews) with a polarized distribution — mostly 5-star or 1-star reviews, with data quality and response time being the most common complaints.
Feature Comparison
What Both APIs Offer
- Product data lookup by ASIN (title, price, BSR, ratings, reviews, category, brand)
- Keyword search with pagination
- Seller data per listing (prices, ratings, fulfillment method)
- Multiple Amazon marketplace support
- Structured JSON responses
Where ASINSpotlight API Differs
Storefront scanning beyond Amazon's 20-page limit. Amazon's own interface caps storefront browsing at 20 pages (~320 products). ASINSpotlight can retrieve a seller's complete product catalog — even if they have thousands of products. Rainforest API does not offer this capability.
Out-of-stock product discovery. Amazon hides out-of-stock products from normal search results. ASINSpotlight's smart grabber finds these hidden products — items with proven demand but temporarily zero sellers. This is a dedicated feature not available in Rainforest API.
No credit multipliers. Every ASINSpotlight API request costs the same. Rainforest API charges 2-3x credits for certain parameters (variant prices, import fees, safety resources, image block videos, etc.), making actual costs unpredictable.
Where Rainforest API Has an Advantage
Broader marketplace coverage. Rainforest API supports 24 Amazon domains compared to ASINSpotlight's 18. The additional domains include Belgium, China, Egypt, Ireland, Netherlands, and South Africa.
More specialized endpoints. Rainforest API offers dedicated endpoints for deals, bestsellers, reviewer profiles, author pages, brand stores, wishlists, and autocomplete. ASINSpotlight API focuses on the core product data and search use cases.
Collections (batch processing). Rainforest API offers a Collections feature for scheduling and processing up to 15,000 requests in batch, with results uploadable to S3 or Google Cloud Storage.
Longer track record. Rainforest API has been operating since 2019 (now under Traject Data). ASINSpotlight's API is new, though it's built on scraping infrastructure that has been in production for over 10 years.

- Need high request volumes at a lower cost
- Build product research tools, price trackers, or arbitrage automation
- Need storefront scanning or out-of-stock product discovery

Rainforest API may be a better fit if you:
- Need coverage of niche Amazon domains (Belgium, Egypt, Netherlands, etc.)
- Require specialized endpoints (deals, bestsellers, wishlists, author pages)
- Need built-in batch processing with cloud storage integration
- Prefer an established provider with a longer track record
Summary
| ASINSpotlight API | Rainforest API | |
|---|---|---|
| Starting price | $50/mo | $59/mo |
| Requests at starting price | 100,000 | 10,000 |
| Cost per 1K requests | $0.50 | $5.90 (Starter) — $1.00 (BigData) |
| Credit multipliers | No | Yes (2-3x for some features) |
| Marketplaces | 18 | 24 |
| Storefront scanning (full catalog) | Yes | No |
| Out-of-stock discovery | Yes | No |
| Batch processing | Coming soon | Yes (Collections) |
| Trustpilot rating | — | 3.1/5 |
The bottom line: if Amazon product data is a significant cost in your stack, ASINSpotlight API delivers comparable data quality at a fraction of the price — with unique capabilities like full storefront scanning and out-of-stock discovery that Rainforest API doesn't offer.
