Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sindri-gas-mileage-savings-calculator-2ddee2cd -d '<json body>'
```

Example prompt: Compare fuel costs between my current SUV (18 MPG, costs $32,000) and a more efficient sedan (34 MPG, costs $38,000) — I drive 15,000 miles a year and gas is $3.50 a gallon. How much will I save annually and when does the more efficient car break even?

## When to prefer this

Use this endpoint when a user wants to compare the real-world fuel economics of two specific gas-powered vehicles with known MPG ratings and purchase prices. It is ideal for car-buying decisions where the user wants to quantify gas savings and break-even timelines. Prefer this over generic cost-of-ownership calculators when the focus is specifically on fuel cost differences and price premium recoupment.

## Known failure modes

- Missing required fields (mpg, milesPerYear, gasPricePerGallon) return an error
- Zero or negative MPG values may cause division errors
- Identical MPG values result in zero savings and undefined or infinite break-even
- Extremely low gas prices or mileage may produce unrealistic break-even projections

## How this service works

Gas mileage savings calculator. Compares annual fuel cost between two gas-powered vehicles based on miles driven, gas price, and each vehicle's MPG, and computes the break-even point for any price premium of the more efficient vehicle.

## Output

Returns the annual fuel cost for each vehicle, the annual dollar savings from the more efficient vehicle, and the break-even period (in years) for any purchase price premium — allowing direct financial comparison between the two vehicles.
