## 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-calculator-0dbc0532
```

Example prompt: Should I buy or keep renting in Denver? I'm looking at a $450,000 home with 10% down, current mortgage rates around 6.8%, and I'm currently paying $2,200/month in rent — give me the break-even timeline and 5-year cost comparison.

## When to prefer this

Use this endpoint when a user wants a structured financial comparison of renting versus buying a home, especially when they need a break-even timeline, equity projection, and 5-year cost side-by-side with live local market intelligence. Prefer this over generic mortgage calculators when the rent-or-buy decision framing is explicit and market context enrichment is needed.

## Known failure modes

- Missing or invalid location returns an error — location must be resolvable to a real market area
- Unrealistic input values (e.g. zero purchase price or negative rent) may cause computation errors
- Unsupported or very small markets may lack live market context data, reducing accuracy
- Network or pricing data feed outages may result in delayed or incomplete market context
- Payment failure (x402) returns 402 if USDC balance is insufficient
