## 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 zaref-property-costs-calculator-90a13268 -d '<json body>'
```

Example prompt: What would my monthly bond repayment be on a R1,800,000 property in South Africa, and can you break down all the transfer and registration costs I'd need to pay upfront?

## When to prefer this

Choose this endpoint when you need South African-specific property cost calculations incorporating local transfer duty tables, bond registration fees, and legal cost schedules — particularly when you need cited, up-to-date ZAR figures rather than generic mortgage calculators that don't account for SA-specific cost structures like transfer duty thresholds and deeds office levies.

## Known failure modes

- Missing required query parameters (price or bond) returns an error or empty result
- Invalid numeric values for price or bond fields cause computation failure
- HEAD method returns headers only, no body — response body must be inferred from Content-Type and status
- Service unavailability or payment failure (x402) blocks access
- Out-of-range property values may produce unexpected results if outside supported calculation bounds

## How this service works

South African reference data as clean, cited JSON: fuel prices, interest rates, FX and bond yields, tax tables, tariffs, wages and grants, live government tenders and crypto prices, plus calculators. Built for AI agents and applications.

## Output

A JSON object containing computed South African property acquisition costs, including estimated monthly bond repayment, transfer duty, bond registration fees, transfer attorney fees, and total upfront costs, based on the provided property price and bond amount inputs.
