Below is a quickstart guide in Python demonstrating how to call three primary endpoints using the requests library:
  1. Aggregated Crash Data
  2. Commercial Auto Garaging
  3. Commercial Auto Telematics (file upload + job polling)
You can install the requests library using pip: 
pip install requests
Note
  • Replace YOUR_API_KEY with your actual API key or token.
  • If any endpoint is restricted in your plan or environment, you may receive 403 errors.
  • Make sure you have installed requests (e.g. pip install requests).
  • The examples below show minimal usage. Adjust request payloads as needed.

​
Get an API Key

Create an API key in the dashboard here, which you’ll use to securely access the API. Store the key in a safe location, like a .zshrc file or another text file on your computer. Once you’ve generated an API key, export it as an environment variable in your terminal. For the sake of this example, we’ll use MATRISK_API_KEY.

​
Make your first API request

​
1. Aggregated Crash Data

View documentation Endpoint 

POST /crash-data/aggregate
This endpoint allows you to get aggregated crash statistics for a particular location and date range. 
import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.risk.matrisk.ai/v1"

def get_aggregated_crash_data():
    url = f"{BASE_URL}/crash-data/aggregate"
    headers = {
        "Authorization": f"Bearer {API_KEY}",
        "Content-Type": "application/json"
    }
    payload = {
        "location": {
            "latitude": 37.7749,
            "longitude": -122.4194
        },
        "start_date": "2020-01-01T00:00:00",
        "end_date": "2021-12-31T00:00:00",
        "radius_km": 50
    }

    r = requests.post(url, json=payload, headers=headers)
    r.raise_for_status()
    data = r.json()
    print(data)


get_aggregated_crash_data()
Example Response 
{
  "latitude": 37.7749,
  "longitude": -122.4194,
  "start_date": "2020-01-01T00:00:00",
  "end_date": "2021-12-31T00:00:00",
  "radius_km": 50.0,
  "total_crashes": 123,
  "total_injuries": 7,
  "total_fatalities": 1,
  "incomplete_coverage": false
}

​
2. Commercial Auto Garaging

View documentation Endpoint 
POST /risk-score/ca-garaging
This endpoint calculates a risk score for vehicles based on their primary garaging locations in a commercial auto context.
Note: Although this example is for commercial auto, the PPA garaging is the same structure (without the naics_code field). 
import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.risk.matrisk.ai/v1"

def get_commercial_auto_risk_score():
    url = f"{BASE_URL}/risk-score/ca-garaging"
    headers = {
        "Authorization": f"Bearer {API_KEY}",
        "Content-Type": "application/json"
    }
    payload = {
        "version": "v2",
        "policy_holder_id": "policy-holder-123",
        "vehicles": [
            {
                "vehicle_id": "vehicle-123",
                "garaging_location": {
                    "latitude": 37.7749,
                    "longitude": -122.4194
                }
            },
            {
                "vehicle_id": "vehicle-456",
                "garaging_location": {
                    "latitude": 34.0522,
                    "longitude": -118.2437
                }
            }
        ]
    }

    r = requests.post(url, json=payload, headers=headers)
    r.raise_for_status()
    data = r.json()
    print(data)

get_commercial_auto_risk_score()
Example Response 
{
  "job_type": "ca-garaging-risk-score",
  "version": "v2",
  "policy_holder_id": "policy-holder-123",
  "vehicle_risk_scores": [
    {
      "vehicle_id": "vehicle-123",
      "vehicle_risk_score": 62.2
    },
    {
      "vehicle_id": "vehicle-456",
      "vehicle_risk_score": 37.9
    }
  ]
}

3. Personal Auto Telematics

View documentation Endpoints 
POST /risk-score/ppa-telematics
GET  /risk-score/ppa-telematics/job/{job_id}/status
GET  /risk-score/ppa-telematics/job/{job_id}/result
This flow calculates a risk score for a personal auto policy based on telematics data uploaded via CSV.
Note: Although this example is for personal auto, the CA telematics is the same structure.
Sample CSV
You can download a sample-ppa-telematics.csv file to try out.

​
a) Queue a Telematics Job

import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://www.api.risk.matrisk.ai/v1"

def queue_ppa_telematics_job():
    url = f"{BASE_URL}/risk-score/ppa-telematics"
    headers = {
        "Authorization": f"Bearer {API_KEY}"
    }

    data = {
        "version": "v2",
        "policy_holder_id": "policy-holder-123"
    }

    with open("sample-ppa-telematics.csv", "rb") as f:
        files = {"file": ("sample-ppa-telematics.csv", f, "text/csv")}
        r = requests.post(url, files=files, data=data, headers=headers)

    r.raise_for_status()
    job_info = r.json()
    job_id = job_info["job_id"]
    print("Queued job ID:", job_id)
    return job_id


queue_ppa_telematics_job()
Example Response (job queued) 
{
  "job_id": "job_a1b2c3d4",
  "status": "processing",
  "error_message": null
}

​
b) Check the Job Status

import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://www.api.risk.matrisk.ai/v1"

def get_ppa_telematics_job_status(job_id: str):
    url = f"{BASE_URL}/risk-score/ppa-telematics/job/{job_id}/status"
    headers = {
        "Authorization": f"Bearer {API_KEY}"
    }
    r = requests.get(url, headers=headers)
    r.raise_for_status()
    status_info = r.json()
    print("Status:", status_info)
    return status_info


status_data = get_ppa_telematics_job_status("job_a1b2c3d4")
Example Response (job status) 
{
  "job_id": "job_a1b2c3d4",
  "status": "processing",
  "error_message": null
}

​
c) Retrieve Final Result

import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://www.api.risk.matrisk.ai/v1"

def get_ppa_telematics_job_result(job_id: str):
    url = f"{BASE_URL}/risk-score/ppa-telematics/job/{job_id}/result"
    headers = {
        "Authorization": f"Bearer {API_KEY}"
    }
    r = requests.get(url, headers=headers)
    r.raise_for_status()
    result_data = r.json()
    print("Final Result:", result_data)
    return result_data


result = get_ppa_telematics_job_result("job_a1b2c3d4")
Example Response (final result) 
{
  "job_type": "ppa-telematics-risk-score",
  "policy_holder_id": "policy-holder-123",
  "version": "v2",
  "vehicle_risk_scores": [
    {
      "vehicle_id": "vehicle-123",
      "vehicle_risk_score": 20.1,
      "metadata": {
        "start": "2023-01-01T12:00:00",
        "end": "2023-06-01T12:00:00",
        "num_trips": 56,
        "exposure_seconds": 8100,
        "state_exposure": [
          {
            "usstate": "OH",
            "exposure_seconds": 4050,
            "share": 0.5
          },
          {
            "usstate": "MI",
            "exposure_seconds": 4050,
            "share": 0.5
          }
        ]
      }
    }
  ]
}

Additional Notes

  • File Upload: When using the telematics endpoint, you must send your CSV as multipart/form-data. The snippet above shows how to open a local file in Python and upload it.
  • Status Polling: Real-time processing can take several seconds to a few minutes. Continuously call the status endpoint until the status changes from processing to completed or failed. Once completed, fetch the final result.
