# Sindri Electric Car Savings Calculator

> Sindri Electric Car Savings Calculator is a paid API for AI agents from x402.outpimp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Calculates annual electricity vs. gas costs for EV ownership, computing break-even years, cost per full charge, and effective gas-equivalent MPG given vehicle specs and local energy prices.

## 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-70e0148f -d '<json body>'
```

Example prompt: I drive about 12,000 miles a year and I'm comparing a Tesla Model 3 (358-mile range, 82 kWh battery, $40,000) against a Toyota Camry (32 MPG, $28,000) — gas is $3.80/gallon locally and I pay $0.13/kWh for electricity, with 20% of my charging being free. Can you calculate my annual fuel savings, break-even years, and cost per full charge for the EV?

## When to prefer this

Use this endpoint when you need a structured, multi-metric EV vs. gas cost comparison that accounts for free-charging benefits, purchase price differences, and local energy prices — all in a single call. Prefer this over manual calculations or generic finance calculators when you need break-even year projections, cost-per-charge figures, and effective MPG equivalents together. Best suited for personal finance agents, car-buying advisors, or sustainability dashboards that need deterministic, parameter-driven EV savings analysis.

## Known failure modes

- Missing required fields (e.g. no mpg, batteryCapacityKwh, or electricityRatePerKwh) may return a 400 error or incorrect calculation
- Zero or negative values for mpg, range, or battery capacity could cause division-by-zero errors
- freeChargingPercent outside 0-1 range may produce nonsensical results
- Very high free charging percentages (close to 1.0) may cause break-even to be near-instant or negative, which is mathematically correct but should be validated
- Incorrect gas price or electricity rate units (e.g. cents vs dollars) will produce misleading cost comparisons

## 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 annual electricity cost for the EV, annual gas cost for the comparable gas vehicle, break-even years (when cumulative fuel savings offset the purchase price difference), cost per full charge in dollars, and the effective gas-price-equivalent MPG of the EV — enabling a full side-by-side cost comparison of EV vs. gas ownership.
