Amazon Search API for Product Research

Search Amazon products with structured data

The Amazon Search API lets you search by keyword or exact ASIN list. Depending on the current contract, results can include product details, price, estimated sales, ratings, review counts, and listing data.

Endpoint and authentication

• Method: POST
• Canonical endpoint: https://ecommercedataapi.com/v1/amazon/product/competitor-lookup
• MCP Code: competitor_lookup

Send your key in the X-API-Key header. Never expose it in browser code, repositories, or logs.

curl --request POST \
  --url https://ecommercedataapi.com/v1/amazon/product/competitor-lookup \
  --header "Content-Type: application/json" \
  --header "X-API-Key: ${ECOMMERCE_DATA_API_KEY}" \
  --data '{
    "marketplace": "US",
    "keyword": "wireless charger",
    "match_type": "broad",
    "include_variations": false,
    "page": 1,
    "size": 20
  }'

Use marketplace, keyword or asins, match_type, include_variations, page, and size as supported by the endpoint. Provide exactly one of keyword or asins.

Recommended workflow

Set the marketplace, query, and page size first. Then compare products, categories, and price ranges against the decision you are making. Treat results as research evidence, not a guarantee of sales or ranking.

Limits

Data may be delayed, incomplete, or vary by marketplace. Check request_id and the error object for non-2xx responses, and follow the documented 429 handling guidance.
