Google Shopping CLI — FlashData

Compare product offers in a purchasing research pipeline. This command calls the google_shopping API and returns JSON for your shell script, data pipeline or agent tool runner. It does not invoke a language model.

Prices are search snapshots; inventory and checkout price are not guaranteed.

Install and run

Requires Python 3.10 or newer. uv installation provides uvx, which runs this package in an isolated environment.

1. Create a FlashData account, obtain an API Key and fund Credits.
2. Set FLASHDATA_API_KEY using your shell or secret manager. The CLI does not accept a key flag or persist credentials. Authentication and source documentation.
3. Run this example after reviewing the input and cost:

uvx flashdata-google-shopping@0.1.0 --query 'USB microphone' --options-json '{"num": 5}' --output result.json

--output creates a new file with owner-only permissions where supported and refuses existing files before making a paid request. Without it, the full JSON response goes to stdout. Errors go to stderr. Exit 0 means the response was exported, 2 means local input/configuration failure, and 1 means request or output failure. For downloads, exit 0 can describe an unfinished job.

For repeated use, install uv tool install flashdata-google-shopping==0.1.0; the command name is flashdata-google-shopping. Alternatively use python -m pip install flashdata-google-shopping==0.1.0 in your virtual environment.

Inputs and output

Use --query for the primary input. Additional options use --options-json as a JSON object, with strict field/type/range validation. Source is fixed by this package. Google count and locale options remain omitted unless supplied.

Run uvx flashdata-google-shopping@0.1.0 --schema to inspect all fields, nested filters, allowed values and defaults without a Key or an API call. --help and --version are also local-only.

The JSON output preserves the API result envelope and optional fields: results[].shopping: title, link, price and available merchant/rating fields; usage.credits. Missing fields remain missing; empty results remain empty. No article text, translated captions, model conclusions, rights grants or keyword volumes are invented. Exact source contracts are documented here.

Fees and failure handling

This MIT-licensed CLI is free to install. FlashData API requests consume paid Credits; current pricing applies. Extended YouTube Search has a separate rate. Media delivery is billed by delivered volume, and your cloud-storage costs are separate. There is no automatic pagination, retry, polling, scheduled execution or model call.

Each HTTP request has a 120-second network timeout (15-second connect timeout) and a 20-MiB response limit. A timeout or failure may occur after a paid request has been accepted. Check Jobs in the FlashData console before resubmitting. HTTP 401 means check the Key; 402 means insufficient Credits; 429 means rate/quota limit. A partial output file is retained on failure. Do not retry a paid query just because output handling failed.

Input values and your API Key are sent to FlashData to perform the request. A completed download-result read may fetch a signed JSON object from the result origin returned by FlashData; the API Key is never sent to that object URL. Only process data appropriate for your output destination. Privacy policy.
