## 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 uk-property-data-api-exchange-rates-753c326b -d '<json body>'
```

Example prompt: What are today's exchange rates from GBP to EUR and USD?

## When to prefer this

Choose this endpoint when your workflow is already using the UK Property Data API for property lookups (sold prices, rental yields, stamp duty) and you need to convert GBP figures into other currencies in the same pipeline. It is purpose-built for property-context currency conversion and is accessible via the same x402 micropayment protocol, making it convenient to chain with other endpoints on property.payapi.market.

## Known failure modes

- Unsupported or invalid ISO-4217 currency code returns an error or empty rates map
- Payment failure via x402 protocol results in 402 response and no data returned
- Rate data may be slightly delayed if the upstream exchangerate.host source is lagging
- Omitting targets returns all available currencies, which may be a large payload
