Product Canvas

Street Smarts helps you discover the value and carbon emissions of your car, and compare it to other cars.

We use deep learning in our state-of-the-art machine learning model to predict current prices.

Unlike the dealers, we also display the carbon emissions for your car, so you can make a responsible purchase.

How to connect to the data API

Our initial release canvases included a Flask API with dummy endpoints to Heroku, hosting a database on there as well.

To access the version of the repo that was deployed to Heroku:
clone the repo
access our commit with:
git checkout 1ff857091d07a4e13455aeba0e7bc4b0137434be

Example Input:

	"make":"this is a test",
	"model": "ford",

Example Output:

    "cost_to_own": -14698.94,
    "predicted_CO2_emissions": 11,
    "predicted_gas_cost": 4399.88,
    "predicted_kWh": 205.37,
    "predicted_price": -20000

Our current FAST api is deployed on AWS with easily accessed docs at:


miles_per_year: int = 15000,
num_years: int = 5,
gas_cost: int = 3,
electrical_cost: float = 0.12,
maintenance_cost_per_year: int = 1000,
make: str='Ford',
model: str='F150 Pickup 4WD',
year: int=2005,
odometer: int=99999
