Etsy Open API vs Rainforest API: handmade and vintage listings or Amazon data, scraped
Etsy Open API is Etsy's REST API for listings, shops, inventory and orders on the Etsy marketplace. Rainforest API is a paid third-party API that returns Amazon search, product, offer and review data in real time.
The short answer
- Etsy Open API: Searching handmade, vintage and craft listings from independent Etsy sellers.
- Rainforest API: Getting Amazon product, price and review data without needing Amazon Associates sales.
Side by side
| Etsy Open API | Rainforest API | |
|---|---|---|
| Searches | All active Etsy listings (findAllListingsActive, with keyword search), plus shops and shop listings. | Amazon search results by keyword or category, product pages by ASIN, deals and offers, and reviews. |
| Returns | Listing records including title, price and the full URL of the listing page on Etsy. | Ranked products with ASINs, title and price for searches; full product page data (bullets, descriptions, attributes, variations, category tree) by ASIN. |
| Before the first call | A registered app with an API keystring and shared secret; apps used beyond your own shop go through review (Personal App), and wider use needs a separately approved Commercial Access request. Searching active listings needs only the API key, not OAuth. | A Traject Data account and API key. |
| Free | Not stated on its pages | A free trial; the pricing page does not say how many requests it includes. |
| Paid | Not stated on its pages | Hobbyist plan $23 a month billed annually for 500 credits a month ($0.06 per extra credit). |
| Acting on a result | Buy link: each listing has its Etsy page URL; buying happens on Etsy. | Data only; no buy, affiliate or checkout action is described. |
| Coverage | The Etsy marketplace (sellers worldwide). | Amazon marketplaces worldwide, including US, UK, DE, FR, CA and IN. |
| MCP server | Etsy Dev MCP server at https://mcp.api.etsycloud.com/mcp, but it only teaches an assistant the API docs and schemas; it does not call the Etsy API or return listings. | No official server listed |
