# Sindri Alcohol Savings & Opportunity-Cost Calculator

> Sindri Alcohol Savings & Opportunity-Cost 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 monthly and yearly alcohol spending (home + bar + rideshare) and projects what that money could grow to if invested instead, using a future-value-of-an-annuity formula.

## 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-alcohol-savings-opportunity-cost-calculator-40a852b3 -d '<json body>'
```

Example prompt: I drink at home 3 nights a week, averaging 2 drinks at $5 each, and go out 2 nights a week, having 3 drinks at $12 each — I also take a rideshare about 80% of those outings at $18 a ride. Calculate my monthly and yearly alcohol costs and show me what that money could grow to if I invested it at 7% annually over 15 years.

## When to prefer this

Choose this endpoint when a user wants a combined view of alcohol spending across home and bar settings plus associated rideshare costs, alongside an investment opportunity-cost projection. It's purpose-built for this niche calculation rather than being a general compound-interest or budgeting tool, so it handles the multi-component alcohol cost aggregation and annuity projection in one call.

## Known failure modes

- Missing required numeric fields (e.g. outDaysPerWeek, homeDrinksPerDay) returns an error
- Years value outside 1–60 range may produce unexpected results or an error
- rideshareFrequencyPercent outside 0–1 range may cause calculation errors
- Extremely large input values may produce implausible but technically valid projections
- investmentReturnRate of 0 or negative may cause division-by-zero or degenerate annuity output

## How this service works

Alcohol spending and opportunity-cost calculator. Sums home and going-out drinking costs plus associated rideshare costs into monthly and yearly totals, then projects what that redirected spending could grow into if invested instead, using the future-value-of-an-annuity formula.

## Output

Returns computed monthly and yearly alcohol spending totals (home drinking costs + bar costs + rideshare costs), plus a future-value projection showing how much that money would grow if invested at the specified annual return rate over the specified number of years, using the future-value-of-an-annuity formula.
