## 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 arch-tools-currency-converter-6c3fb736 -d '<json body>'
```

Example prompt: Convert 250 USD to JPY for me — I need to know how much that is in Japanese yen right now.

## When to prefer this

Choose this endpoint when you need a simple, on-demand currency conversion between two currency codes (fiat or crypto) without building your own exchange rate pipeline. It's ideal for agent workflows that need quick, pay-per-use conversion without managing API keys or subscriptions. Prefer this over free public APIs when you need reliable uptime and crypto (e.g. BTC, ETH) support alongside fiat pairs.

## Known failure modes

- Unsupported or invalid currency code returns an error
- Amount must be a positive number; zero or negative values may be rejected
- Network or rate-feed outage may cause service unavailability
- Payment failure (insufficient USDC balance) blocks the request
- Highly exotic or delisted currencies may not be supported
