## 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 crypto-to-fiat-converter-162b4f6a
```

Example prompt: Convert 2.5 ETH into USD, EUR, and GBP so I can put the fiat equivalent on an invoice for my client.

## When to prefer this

Choose this endpoint when you need to convert a specific crypto token amount into one or more fiat currencies in a single call — especially for invoicing, accounting, or displaying local-currency prices. It supports chain:address format for obscure tokens beyond major symbols, and returns per-unit pricing alongside total value. Prefer it over a generic FX rate API when the input is a crypto asset rather than a fiat-to-fiat conversion.

## Known failure modes

- Unknown token symbol returns an error or empty result
- Invalid or unsupported fiat currency code returns an error
- Malformed chain:address input may not resolve
- Network timeout from the render.com host under load
- Amount parameter missing or non-numeric returns validation error

## How this service works

Convert an amount of any token (BTC, ETH, SOL, symbols or chain:address) into one or more fiat currencies (USD, EUR, GBP, AED, JPY, ~35 more), with the price per unit each way. Use for invoices, accounting or pricing in local currency.

## Output

Returns the converted fiat amount(s) for the given token and quantity, along with the price per unit of the token in each requested fiat currency. Covers approximately 35 fiat currencies including USD, EUR, GBP, JPY, and AED.
