# BloodHound: query an identity graph



Query an identity graph.



## 1. Run the example



[Download the BloodHound example](https://www.security.run/docs/examples/bloodhound.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 graph-result.json for the query result and negative-result.json for the comparison.



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



- `run.py`

- `config.json`

- `graph.zip`

- `query.txt`



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: `9.9.2`. Commands: `bloodhound`, `python`, `postgres`, `initdb`, `pg_ctl`, `psql`, `createdb`.



- Includes the native CE server and PostgreSQL 17 tools. Supply server/database configuration and identity-graph input, including crypto.argon2 memory settings within the executor budget. Upstream password-hash defaults exceed the 1 GiB resource class; large graph analysis also requires a larger executor.



Inspect `GET /v1/tools/bloodhound` for the current installed version and readiness. The published snapshot has 1 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.
