# Sindri Electric Car Savings Calculator

> Sindri Electric Car 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).

Calculates annual electricity vs. gas cost savings for an EV compared to a gas vehicle, including break-even years, cost per charge, and effective MPG equivalent.

## 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-electric-car-savings-calculator-f8ec306f -d '<json body>'
```

Example prompt: I'm thinking of buying a Tesla Model 3 (purchase price $40,000, 358-mile range, 82 kWh battery) to replace my Honda Accord (30 MPG, $28,000). I drive 15,000 miles a year, electricity costs $0.13/kWh, gas is $3.50/gallon, and about 20% of my charging would be free — can you calculate my annual savings, break-even point, and effective MPG?

## When to prefer this

Use this endpoint when an agent or user needs a detailed, multi-factor financial comparison between owning an EV versus a comparable gas vehicle — particularly when free charging, local electricity rates, specific battery capacity, and purchase price differentials all need to be incorporated. Prefer this over generic fuel-cost calculators when break-even analysis and effective MPG equivalency are required outputs.

## Known failure modes

- Missing required fields (e.g. no MPG, battery capacity, or electricity rate) returns a validation error
- Implausible values (e.g. 0 kWh battery or 0 miles/year) may produce division-by-zero or nonsensical results
- freeChargingPercent outside [0,1] range may cause incorrect savings computation
- Network timeout or Lambda cold-start latency on first invocation
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Electric car savings calculator. Compares annual electricity cost against annual gas cost for a comparable gas vehicle, accounting for free-charging usage, and computes break-even years, cost per full charge, and gas-price-equivalent effective MPG.

## Output

Returns a structured breakdown including annual electricity cost, annual gas cost for the comparable vehicle, annual dollar savings, break-even years between EV and gas vehicle purchase prices, cost per full charge, and the effective gas-price-equivalent MPG for the electric vehicle.
