# Hybrid vs Gas Savings Calculator

> Hybrid vs Gas Savings Calculator is a paid API for AI agents from ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Compares annual fuel costs between a hybrid and a conventional gas vehicle and calculates the break-even point for the hybrid's price premium.

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 hybrid-vs-gas-savings-calculator-3b56652a -d '<json body>'
```

Example prompt: I'm deciding between a Toyota Prius at $28,000 getting 50 MPG and a Honda Civic at $23,000 getting 32 MPG — I drive about 12,000 miles a year and gas near me is $3.80 a gallon. How many years until the Prius pays for itself in fuel savings?

## When to prefer this

Use this endpoint when a user wants a deterministic, arithmetic comparison of fuel costs between exactly two vehicles — especially when the break-even payback period for a hybrid's price premium is needed. Prefer this over general financial calculators because it is specifically structured for the hybrid-vs-gas vehicle scenario with MPG, annual mileage, and gas price inputs, and returns break-even in years directly.

## Known failure modes

- Missing required fields (mpg, purchasePrice for either vehicle, milesPerYear, gasPricePerGallon) results in an error
- Zero or negative MPG values may cause division-by-zero or nonsensical results
- Zero miles per year returns zero savings and an undefined break-even
- If both vehicles have the same purchase price, break-even is immediate (year 0) which may be unexpected
- Payment failure or insufficient USDC balance returns a 402 error before computation

## How this service works

Hybrid vs gas savings calculator. Compares annual fuel cost between a hybrid and a conventional gas vehicle based on miles driven, gas price, and each vehicle's MPG, and computes the break-even point for the hybrid's price premium.

## Output

Returns the annual fuel cost for each vehicle, the annual savings from choosing the more efficient vehicle, and the break-even year at which the higher purchase price of the hybrid is offset by cumulative fuel savings.
