# OSV-Scanner: check dependencies with an offline database



Check dependencies with an offline database.



## 1. Run the example



[Download the OSV-Scanner example](https://www.security.run/docs/examples/osv-scanner.zip). Extract it, install `httpx`, set your API URL and token, then run `python client.py`. The client uploads the included inputs, submits the command, and saves the result under `results/RUN_ID`.



## 2. Check the result



Read JSON stdout for findings from requirements.txt and the supplied OSV data.



Read the native exit code and cleanup status printed by the client. [Read results and save reports](https://www.security.run/docs/visibility.html) explains the returned files.



## 3. Use your own inputs



Edit `example.json` to change the command arguments, requested outputs or deadline. Replace the files under `inputs/` with your own data, keeping the staged paths aligned with the command. The client creates the artifact IDs for you; illustrative IDs shown here must not be copied into a live request.



### Files used by this example



- `requirements.txt`

- `db/osv-scalibr/PyPI/all.zip`



The example uses supplied files or the disposable execution environment. Nothing from the environment carries into a later run unless you request and reuse its output.



Qualified version: `2.7.1`. Commands: `osv-scanner`.



- Disconnected scanning requires a supplied local database; API scanning needs reachable services.



Inspect `GET /v1/tools/osv-scanner` for the current installed version and readiness. The published snapshot has 2 functional case(s), plus timeout and cancellation checks. These examples demonstrate the native path; other flags and inputs are supported within the tool’s runtime limits.
