Prerequisites

Required

• Python 3.8+ (uses only the standard library -- zero external dependencies)
• Pangolin account at pangolinfo.com
• Environment variables (one of the following):
  • PANGOLIN_API_KEY -- API key (skips login), OR
  • PANGOLIN_EMAIL + PANGOLIN_PASSWORD -- auto-login with caching

macOS SSL Certificate Fix

On macOS, Python may fail with CERTIFICATE_VERIFY_FAILED because it ships without root certificates by default.

Symptoms: The script exits with error code SSL_CERT.

Solutions (pick one):

1. Run the certificate installer bundled with Python:

   bash

   /Applications/Python\ 3.x/Install\ Certificates.command
   

   (Replace 3.x with your Python version, e.g., 3.11)

2. Set SSL_CERT_FILE from the certifi package:

   bash

   pip3 install certifi
   export SSL_CERT_FILE=$(python3 -c "import certifi; print(certifi.where())")
   

3. Add the export to your shell profile (~/.zshrc or ~/.bashrc) so it persists.

First-Time Setup Guide

When a user tries to use this skill and authentication fails (error code MISSING_ENV), do not just repeat the error hint. Instead, walk the user through the full setup process interactively:

Step 1: Explain what's needed

Tell the user (in their language):

To use this skill, you need a Pangolin API account. Pangolin provides Amazon product data scraping through its APIs.

使用本技能需要 Pangolin API 账号。Pangolin 提供亚马逊商品数据抓取的 API 服务。

Step 2: Guide registration

1. Go to pangolinfo.com and create an account

2. After login, find your API Key in the dashboard

3. 访问 pangolinfo.com 注册账号

4. 登录后在控制台找到你的 API Key

Step 3: Collect credentials and authenticate automatically

When the user provides their credentials, you (the AI agent) should configure them securely. The script will automatically cache the API key at ~/.pangolin_api_key for all future calls.

If user provides an API key (recommended): Write it directly to the cache file — avoids shell history entirely:

bash

echo "<api_key>" > ~/.pangolin_api_key
chmod 600 ~/.pangolin_api_key 2>/dev/null
python3 scripts/pangolin.py --auth-only

If user provides email + password: Set env vars in the session and clean up after auth:

bash

export PANGOLIN_EMAIL="[e-mail]"
export PANGOLIN_PASSWORD="their-password"
python3 scripts/pangolin.py --auth-only
unset PANGOLIN_EMAIL PANGOLIN_PASSWORD

This avoids passwords appearing in shell history (unlike inline VAR=x command syntax) and cleans up credentials after the API key is cached.

Both methods cache the API key automatically. After this one-time setup, no environment variables are needed — all future calls will use the cached API key at ~/.pangolin_api_key.

Step 4: Confirm and proceed

After auth returns "success": true:

1. Tell the user: "认证成功！API Key 已自动缓存，后续使用无需再次输入。" / "Authentication successful! API Key cached — no need to enter credentials again."
2. Immediately retry their original request.

Important

• The user only needs to provide credentials ONCE — the script caches the API key permanently at ~/.pangolin_api_key
• Do not ask the user to manually edit .bashrc or .zshrc — the script handles persistence automatically
• If the user doesn't have an account yet, explain Pangolin's credit system (1 credit per Amazon json request, 5 credits per review page) and direct them to pangolinfo.com
• If auth succeeds but credits are exhausted (error code 2001), tell the user to top up at pangolinfo.com
• The API key is permanent and does not expire unless the account is deactivated

Script Execution

The script is located at scripts/pangolin.py relative to this skill's root directory.

Path resolution: When invoking the script, resolve the absolute path from the skill directory. For example, if this skill is installed at /path/to/pangolinfo-amazon-scraper/:

bash

python3 /path/to/pangolinfo-amazon-scraper/scripts/pangolin.py --content B0DYTF8L2W --mode amazon --site amz_us

Intent-to-Command Mapping

1. Product Detail by ASIN

User says: "Look up B0DYTF8L2W on Amazon" / "查一下 B0DYTF8L2W 这个产品"

bash

python3 scripts/pangolin.py --content B0DYTF8L2W --mode amazon --site amz_us
# Or using the --asin shortcut:
python3 scripts/pangolin.py --asin B0DYTF8L2W --site amz_us

The script auto-detects 10-character alphanumeric codes as ASINs and selects amzProductDetail. The --asin flag is a convenience shortcut that sets --content and defaults to amzProductDetail parser automatically.

2. Keyword Search

User says: "Search Amazon for wireless mouse" / "在亚马逊搜索无线鼠标"

bash

python3 scripts/pangolin.py --q "wireless mouse" --mode amazon --site amz_us

Non-ASIN text auto-selects amzKeyword parser.

3. Bestsellers

User says: "Show me electronics bestsellers" / "看看电子产品畅销榜"

bash

python3 scripts/pangolin.py --content "electronics" --mode amazon --parser amzBestSellers --site amz_us

4. New Releases

User says: "What's new in toys on Amazon?" / "亚马逊玩具类有什么新品？"

bash

python3 scripts/pangolin.py --content "toys" --mode amazon --parser amzNewReleases --site amz_us

5. Category Products

User says: "Browse category 172282 on Amazon" / "浏览亚马逊分类 172282"

bash

python3 scripts/pangolin.py --content "172282" --mode amazon --parser amzProductOfCategory --site amz_us

6. Seller Products

User says: "Show products from seller A1B2C3D4E5" / "查看卖家 A1B2C3D4E5 的商品"

bash

python3 scripts/pangolin.py --content "A1B2C3D4E5" --mode amazon --parser amzProductOfSeller --site amz_us

7. Follow Seller (Variant / Seller Options)

User says: "Show other seller options for B0G4QPYK4Z" / "查看 B0G4QPYK4Z 的其他卖家选项"

bash

python3 scripts/pangolin.py --asin B0G4QPYK4Z --parser amzFollowSeller --site amz_us

Uses a dedicated API endpoint (/api/v1/scrape/follow-seller). Returns variant options including price, delivery, fulfillment, and seller info for the given ASIN.

8. Product Reviews

User says: "Get critical reviews for B00163U4LK" / "看看 B00163U4LK 的差评"

bash

python3 scripts/pangolin.py --content B00163U4LK --mode review --site amz_us --filter-star critical

Star filter mapping:

User says (EN)	User says (CN)	--filter-star value
all reviews	所有评论	all_stars
5-star / excellent	五星 / 好评	five_star
4-star	四星	four_star
3-star	三星	three_star
2-star	两星	two_star
1-star / terrible	一星 / 最差评	one_star
positive / good	好评 / 正面评价	positive
critical / negative / bad	差评 / 负面评价	critical

Sort mapping:

User says (EN)	User says (CN)	--sort-by value
newest / most recent	最新的	recent
most helpful / top	最有帮助的	helpful

Multiple pages: Add --pages N (each page costs 5 credits).

9. Product by URL (Legacy)

User says: "Scrape this Amazon page: https://www.amazon.com/dp/B0DYTF8L2W"

bash

python3 scripts/pangolin.py --url "https://www.amazon.com/dp/B0DYTF8L2W" --mode amazon

The site code is auto-inferred from the URL domain.

10. Different Region

User says: "Check price on Amazon Japan" / "看看日本亚马逊的价格"

Region mapping:

User says (EN)	User says (CN)	--site code
US / America	美国	amz_us
UK / Britain	英国	amz_uk
Canada	加拿大	amz_ca
Germany	德国	amz_de
France	法国	amz_fr
Japan	日本	amz_jp
Italy	意大利	amz_it
Spain	西班牙	amz_es
Australia	澳大利亚	amz_au
Mexico	墨西哥	amz_mx
Saudi Arabia	沙特	amz_sa
UAE	阿联酋	amz_ae
Brazil	巴西	amz_br

Smart Defaults

The script automatically:

1. Detects ASINs -- 10-character alphanumeric strings like B0DYTF8L2W auto-select amzProductDetail
2. Detects keywords -- non-ASIN text like "wireless mouse" auto-selects amzKeyword
3. Defaults to amz_us if no --site is provided
4. Switches to review mode if --filter-star is used or --parser amzReviewV2 is set
5. Infers site from URL when using --url with an Amazon domain

You generally only need --parser for bestsellers, new releases, category, and seller lookups.

Important Notes for AI Agents

1. Never dump raw JSON to the user. Always parse and present results in a structured, readable format following the Response Presentation guidelines above.

2. Match the user's language. If the user writes in Chinese, respond in Chinese. If English, respond in English. This applies to product descriptions, error messages, and suggestions.

3. Be proactive. If a keyword search returns results, highlight the best match. If reviews show a pattern, summarize it. If a product is out of stock, say so immediately.

4. Handle multi-step requests. If the user says "compare this product on US and Japan Amazon," run two queries with different --site values and present a comparison table.

5. Credit awareness. Each request costs credits. Avoid unnecessary duplicate requests. If the user asks for reviews across multiple pages, warn them about the cost (5 credits per page).

6. Error recovery. If a request fails, check the error code and suggest a fix before retrying. Do not retry blindly.

7. ASIN detection. If the user provides a 10-character code starting with B0, it is almost certainly an ASIN. Auto-detect and use --content with no extra prompting.

8. Default to amz_us unless the user specifies a region or the context implies a different marketplace.

9. Security. Never expose API keys, passwords, or full API responses containing authentication data in the conversation.

10. Combine results. When the user asks a compound question (e.g., "find a good wireless mouse under $30 with good reviews"), run a keyword search first, then fetch reviews for the top candidates. Present a consolidated recommendation.
