## 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 suverse-fx-currencies-list-aa2797d8 -d '<json body>'
```

Example prompt: Can you fetch the full list of currencies supported by the Frankfurter ECB rate service so I can populate a currency selector dropdown in my app?

## When to prefer this

Use this endpoint when you need an authoritative, no-key list of ECB Frankfurter-supported currencies with full names — ideal for populating UI dropdowns, validating user-submitted currency codes, or confirming which currencies are available before making conversion requests. Prefer this over scraping Frankfurter documentation or building your own currency list.

## Known failure modes

- Payment failure (402) if USDC micropayment is not provided or fails
- Upstream Frankfurter service unavailability causing empty or error response
- Network timeout from proxy layer
- Malformed request body returning 400 error
