## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability transitpulse-car-free-feasibility-score-6c345106

Example prompt: I'm thinking about relocating to Denver and going completely car-free — can you pull the car-free feasibility score for Denver to see how realistic that would be?

## When to prefer this

Use this endpoint when you need a single quantitative signal about car-free living viability for a specific city — ideal for relocation decision support, urban planning comparisons, or quickly screening cities for car-free lifestyle compatibility. Prefer this over general transit coverage or commute quality endpoints when the core question is specifically whether someone can live without a car.

## Known failure modes

- City not recognized or not in the dataset — returns an error or empty result
- Ambiguous city name (e.g. 'Springfield') with no state/country context — may return incorrect city data
- Service unavailable or payment not processed — returns 402 or 5xx error
- City provided but transit data is insufficient to compute a score

## Output

A car-free feasibility score for the specified city, quantifying how practical it is to live without a car there based on transit infrastructure and related factors.
