## 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 textokit-fx-rates-6f078cb4 -d '<json body>'
```

Example prompt: What are today's official exchange rates for EUR, GBP, BRL, ARS, MXN, and JPY against USD? I need the source URL too so I can cite it on the invoice.

## When to prefer this

Choose this endpoint when you need an official, citable daily reference exchange rate (not intraday or tick-level data) and want the source URL included for audit, invoicing, or compliance purposes. It is ideal for pricing documents, invoices, and financial reports where provenance matters. Prefer this over generic FX APIs when you need central-bank-sourced rates for up to 20 currencies in a single call at minimal cost.

## Known failure modes

- Unsupported or invalid ISO 4217 currency code returns an error
- More than 20 quote currencies in a single request may be rejected
- Rates may not yet be updated if queried very early in the day before the daily publication
- Network or upstream Frankfurter feed outage causes fallback to CC0 feed or error
