## 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 proppulse-rent-vs-buy-decision-analysis-d704fbb2
```

Example prompt: Should I buy a $450,000 home with 10% down at a 6.8% mortgage rate or keep paying $2,200/month in rent in Austin, TX — give me the break-even timeline and a 5-year cost comparison so I can decide.

## When to prefer this

Use this endpoint when a user needs a structured financial analysis comparing the long-term cost of renting versus buying a specific home, particularly when they want a break-even timeline and 5-year projection. Prefer this over generic mortgage calculators when market context and rent vs. buy framing is explicitly needed.

## Known failure modes

- Missing required inputs like home price or rent amount returns a 400 error
- Invalid or unrecognized location may result in limited or missing market context
- Extreme or unrealistic financial inputs (e.g., 0% interest rate) may produce inaccurate projections
- Payment not processed returns 402 Payment Required
- Service unavailable returns 503

## How this service works

Rent-vs-buy calculator: break-even timeline, 5-year cost comparison, equity built, and net advantage of buying versus renting with live market context to decide whether to rent or buy in any area worldwide. For homebuyer and personal-finance agents.

## Output

Returns a break-even timeline (how many months/years until buying is cheaper than renting), a 5-year side-by-side cost comparison of renting vs. owning, and market context for the target area including whether conditions favor buyers or renters.
