Using `curl` and `jq` to interact with the fleet API.

First, create a `env` file with the following contents:

```
export SERVER_URL=https://localhost:8080 # your fleet server url and port
export CURL_FLAGS='-k -s' # set insecure flag
export TOKEN=eyJhbGciOi... # your api token
```

Next set the `FLEET_ENV_PATH` to point to the `env` file. This will let the scripts in the `fleet/` folder source the env file.

# Examples

```
export FLEET_ENV_PATH=./path/to/env/file/fleet_env

# get my user info
./tools/api/fleet/me

    "admin": true,

    "force_password_reset": false,
    "gravatar_url": "",
    "sso_enabled": false
  }
}

# list queries
./tools/api/fleet/queries/list
{
  "queries": []
}

# use jq to filter a specific query and get the id
./tools/api/fleet/queries/list | jq '.queries[]|select(.name == "osquery_info")|.id'
2

# create a query
./tools/api/fleet/queries/create 'system_info' 'SELECT * FROM system_info;'
{
  "query": {
    "created_at": "0001-01-01T00:00:00Z",
    "updated_at": "0001-01-01T00:00:00Z",
    "id": 4,
    "name": "system_info",
    "description": "",
    "query": "SELECT * FROM system_info;",
    "saved": true,
    "author_id": 1,
    "author_name": "admin",
    "packs": []
  }
}

# add query with id=4 to pack with id=2
./tools/api/fleet/schedule/add_query_to_pack 2 4

# get scheduled queries in a pack
./tools/api/fleet/packs/scheduled 2 | jq '.scheduled[]|{"name": .name, "schedule_id": .id, "query_id": .query_id}'

# run a live queries on hosts (queries with id=1 and id=2 on hosts with id=3 and id=4)
./tools/api/fleet/queries/run "[1,2]" "[3,4]"
```

Bash Script - Pulls all hosts based on software _name_ for your Fleet instance, uses jq. Helps if wanting to track down a particular software and see what hosts might be affected.

`./name.sh api_token software_title_id base_url`

```
#!/bin/bash

# Check if we have the correct number of arguments
if [ "$#" -ne 3 ]; then
    echo "Usage: $0 <api_token> <software_title_id> <base_url>"
    exit 1
fi

# Read arguments
API_TOKEN="$1"
SOFTWARE_TITLE_ID="$2"
BASE_URL="$3"

# Get the version IDs for the software title
VERSION_IDS=$(curl -s "${BASE_URL}/software/titles/${SOFTWARE_TITLE_ID}" \
  -H 'accept: application/json, text/plain, */*' \
  -H "authorization: Bearer ${API_TOKEN}" \
  --compressed | jq '.software_title.versions[].id')

# Define a jq filter for deduplicating hosts by id
jq_filter='[.[] | {id: .id, hostname: .hostname}] | unique_by(.id)'

# Make a temporary file to hold all host entries
tmpfile=$(mktemp)

# Loop through each version ID and get the hosts
for version_id in $VERSION_IDS; do
  # Fetch hosts for the current version ID
  curl -s "${BASE_URL}/hosts?software_version_id=${version_id}" \
    -H 'accept: application/json, text/plain, */*' \
    -H "authorization: Bearer ${API_TOKEN}" \
    --compressed | jq '.hosts[]' >> "$tmpfile"
done

# Deduplicate hosts by id and convert to a JSON array
jq -s "$jq_filter" "$tmpfile"

# Remove the temporary file
rm "$tmpfile"
```

Some quick Python to pull all Vuln software per host 
Might be better to do this _backwards_ by host instead of by the software. Attempting to use parallel threading to make it run faster, only helps a little.
