## 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 irish-property-purchase-cost-calculator-api-2ee5d681
```

Example prompt: I'm buying a house in Ireland for €425,000 as a first-time buyer — can you work out the stamp duty and check if I qualify for Help to Buy? My gross income is €65,000 and I have €40,000 as a deposit.

## When to prefer this

Choose this endpoint when you need to compute Irish property purchase costs — specifically stamp duty and Help to Buy eligibility — on a pay-per-call basis with no API key setup. Ideal for agents embedded in Irish property search, mortgage calculators, or financial planning tools needing real transactional property cost data for Ireland specifically.

## Known failure modes

- Missing required 'price' query parameter returns an error
- Non-numeric or malformed price value causes a validation error
- Invalid buyer_type enum value (not first_time, other, or new_build) may return an error or default behavior
- Payment failure or x402 protocol issue blocks access to data

## How this service works

What is the average rent in an Irish area? What is the rent increase limit? What are house prices in a county? Pay-per-call Irish rent and property price data for agents and developers. x402 and MPP, MCP server, no API keys.

## Output

Returns a JSON object with the data date, the stamp duty amount in EUR owed on the purchase, and a flag indicating whether the Help to Buy scheme is applicable to the buyer given the inputs provided.
