Google Shopping Light Search

Google Shopping Light Search

Search Google Shopping Light product listings through Frevana.

Purpose

This skill is for finding lightweight Google Shopping product results.

Inputs:

• q
• optional google_domain
• optional gl
• optional hl
• optional start
• optional device

Output:

• validated response JSON with Google Shopping Light product results
• the same validated JSON saved to a local file on every successful run

This skill validates that the response is JSON, saves it to disk, and returns it unchanged on stdout. Do not rewrite or reshape the returned data unless the user explicitly asks for a transformation.

What This Skill Needs

• user-provided q
• optional google_domain
• optional gl
• optional hl
• optional start
• optional device
• FREVANA_TOKEN in the environment variables, or an explicit --token override for the current run
• curl
• bash
• python3

Execution Order

Use this flow so the request stays simple and reliable:

1. Confirm the user has provided q or an equivalent product search query.
2. Prefer the script over ad hoc curl commands.
3. Let the script read FREVANA_TOKEN first.
4. In interactive shell usage, if FREVANA_TOKEN is missing, the script may prompt for it.
5. In non-interactive or agent workflows, fail fast if the token is missing and tell the user to set FREVANA_TOKEN or pass --token explicitly.
6. Run the script once. It prints the validated JSON to stdout and saves the same JSON to a file.
7. Use the saved JSON file for any follow-up parsing or summarization instead of calling the search API again.
8. Return the validated response JSON, or summarize the most relevant products if the user does not need the full payload.

Commands

Basic shopping light search

bash <skill-path>/scripts/search_google_shopping_light.sh \
  --q "wireless earbuds"

--query is accepted as an alias for --q.

Search with country, language, and Google domain

bash <skill-path>/scripts/search_google_shopping_light.sh \
  --q "wireless earbuds" \
  --google-domain google.com \
  --gl US \
  --hl en

Search with pagination and device

bash <skill-path>/scripts/search_google_shopping_light.sh \
  --q "wireless earbuds" \
  --start 20 \
  --device mobile

Save response JSON to a specific file

bash <skill-path>/scripts/search_google_shopping_light.sh \
  --q "wireless earbuds" \
  --gl US \
  --hl en \
  --output ./out/google-shopping-light-search-result.json

Token override for the current run

bash <skill-path>/scripts/search_google_shopping_light.sh \
  --q "wireless earbuds" \
  --token "your bearer token"

Fixed Request Shape

The script sends this payload shape, omitting optional fields that were not provided:

{
  "q": "wireless earbuds",
  "google_domain": "google.com",
  "gl": "US",
  "hl": "en",
  "start": 20,
  "device": "mobile"
}

Only q is required. Do not invent google_domain, gl, hl, start, or device values when the user did not provide them.

Response Shape

The API returns Frevana JSON. This skill validates the response as JSON and returns it unchanged.

Output

• Success: the script validates that the response body is JSON, writes it to a file, prints the saved path to stderr, and prints the JSON to stdout
• Default file path: ./out/google-shopping-light-search-<UTC timestamp>-<pid>.json
• With --output: the same JSON is written to the specified file path instead of the default path
• Failure: the script prints the response body or parsing error and exits non-zero

Notes

• Require --q or --query
• Do not call the script twice just to save and summarize results. It always saves the same JSON that it prints.
• Use --google-domain only when the user specifies a Google domain such as google.com
• Use --gl when the user requests a specific country or region
• Use --hl when the user requests a specific language
• Use --start when the user requests pagination by result offset
• Use --device only for desktop, mobile, or tablet
• This Light endpoint does not accept sort_by; use google-shopping-search if the user explicitly needs Google Shopping price sorting.
• If curl is missing, stop and tell the user to install curl
• If python3 is missing, stop and tell the user to install python3
• Do not echo the Bearer token back to the user
• Summarize the product results the user actually cares about instead of dumping raw JSON unless they ask for the full payload
