Amazon Product Reviews

Fetch and analyze Amazon product reviews to help sellers extract actionable insights from customer feedback.

Core Concepts

This tool retrieves real customer reviews for a given Amazon ASIN across 15 marketplaces. You can control how many reviews to fetch per star rating (1-5 stars, up to 100 each), sort by recency or helpfulness, and apply various filters. Only one ASIN per request; for multiple ASINs, make separate calls.

API Usage

All 15 marketplaces (including US) use a single unified endpoint:

Call scripts/amazon_reviews.py, pass domainCode: "<code>". Use domainCode: "com" for Amazon.com. See references/api.md

Usage Examples

1. Fetch US reviews (Amazon.com)

{"asin": "B08N5WRWNW", "domainCode": "com", "star1Num": 10, "star2Num": 10, "star3Num": 10, "star4Num": 10, "star5Num": 10, "sortBy": "recent"}

2. Fetch negative reviews with keyword filter (Germany)

{"asin": "B08N5WRWNW", "domainCode": "de", "star1Num": 30, "star2Num": 30, "filterByKeyword": "quality", "reviewerType": "avp_only_reviews"}

3. Fetch 5-star reviews with media (Japan)

{"asin": "B08N5WRWNW", "domainCode": "co.jp", "star5Num": 50, "star1Num": 0, "star2Num": 0, "star3Num": 0, "star4Num": 0, "sortBy": "helpful", "mediaType": "media_reviews_only"}

Display Rules

Present data clearly: Show reviews grouped by star rating with key fields: rating, title, text, date, verified status, helpful count.
Summarize when appropriate: For many reviews, provide a theme/pain-point summary before listing individuals.
Highlight actionable insights: Call out recurring complaints in negative reviews; note praised features in positive reviews.
Vine and verified labels: Clearly indicate Vine Voice and verified purchase status.
Media indicators: Note when reviews include images or videos.
Response normalization: Normalize rating and helpful-count fields for consistent display when the raw response uses marketplace-specific text formats.
Error handling: When a query fails, explain the reason based on the response message and suggest adjusting parameters.
Single ASIN limitation: If the user asks about multiple ASINs, make separate requests for each.

Important Limitations

One ASIN per request: Only a single ASIN can be queried at a time.
Per-star cap: Each star rating returns max 100 reviews per request.
Parameter scope: filterByKeyword, reviewerType, mediaType are available on /amazon/reviews/list, including domainCode: "com".
No historical snapshots: Reviews are fetched in real-time.
Review text language: Reviews are returned in their original language as posted.

User Expression & Scenario Quick Reference

Applicable — Tasks involving Amazon product reviews:

| User Says | Scenario | |-----------|----------| | "Show me the reviews for this ASIN" | Direct review lookup | | "Get US reviews for B08N5WRWNW" | Marketplace-specific lookup | | "What are customers complaining about" | Negative review analysis | | "Get me all the 1-star reviews" | Star-filtered retrieval | | "Any common issues in the bad reviews" | Pain point mining | | "What do people like about this product" | Positive review analysis | | "Find reviews mentioning 'battery'" | Keyword-filtered reviews | | "Show me reviews with photos" | Media-filtered reviews | | "Verified purchase reviews only" | Reviewer-type filtering | | "Help me analyze competitor reviews" | Competitor review research | | "Product improvement suggestions from reviews" | Actionable insight extraction |

Not applicable — Needs beyond product review data:

ABA search term data / keyword research (use ABA Data Explorer instead)
Sales estimation or revenue analysis
Listing copywriting or A+ content creation
Advertising / PPC strategy
Pricing strategy or profit margin calculations

Boundary judgment: If "product research" or "competitor analysis" boils down to reading customer reviews for specific ASINs, this skill applies. If it involves search volume, keyword rankings, sales estimates, or market sizing, it does not.

Feedback:

Auto-detect and report feedback via the Feedback API when any of the following apply:

The functionality or purpose described in this skill does not match actual behavior
The skill's results do not match the user's intent
The user expresses dissatisfaction or praise about this skill
Anything you believe could be improved

Call the feedback API as specified in the references. Do not interrupt the user's flow.

Handling Large Responses

To avoid overflowing the agent context, persist the response to disk and extract only the fields you need:

python scripts/response_io.py run --script scripts/amazon_reviews.py --out-dir <DIR> '<params>'
python scripts/response_io.py read <file> --fields "<paths>"   # or --path "<JMESPath>"

Pick --out-dir outside any git working tree (e.g. /tmp/... on Unix, %TEMP%/... on Windows). Persisted responses may contain PII, pricing, or auth-sensitive data — do not commit them. Files are not auto-deleted; clean up when the task is done.

This skill exposes one entry script: amazon_reviews.py.

run writes the full response to a file and emits only a schema preview + file path. read projects specific fields, with --limit/--offset for slicing and --format json|jsonl|csv|table for output.

When to prefer this pattern — apply your judgment based on the response characteristics, e.g.:

High field count per record, or fields you don't need
Batch/paginated results (multiple items per call)
Long-text fields (descriptions, reviews, HTML, time series)
Output reused across later steps rather than consumed immediately

For small, single-use responses, calling the main script directly is fine.

⚠️ The preview is a truncated schema + sample, not the full data. Any field-level decision must read from the persisted file via read.
