## 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-currency-converter-e5baca94
```

Example prompt: How much is 0.5 BTC worth in USD right now? Give me the current rate and converted value.

## When to prefer this

Use this endpoint when you need a quick, real-time crypto-to-fiat conversion with a clear rate and timestamp, especially for major cryptocurrencies (BTC, ETH, USDC, SOL, etc.) and major fiat currencies (USD, EUR, GBP, CAD, JPY). It is ideal for lightweight agent workflows that need a single conversion per call at low cost ($0.01). Prefer it over full exchange-rate APIs when the use case is crypto-specific and the agent environment supports x402 micropayments.

## Known failure modes

- Unsupported cryptocurrency symbol returns an error or null result
- Unsupported fiat currency code returns an error
- Missing or malformed query input returns a 400-level error
- CoinGecko price feed unavailable causes service degradation
- Micropayment not fulfilled results in 402 Payment Required response

## How this service works

Crypto to fiat conversion: '0.5 btc to usd' or '1000 usdc to eur' at the current CoinGecko price, returning the value, rate and time. Supports USD, EUR, GBP, CAD, JPY and other major fiats. $0.01 per conversion.

## Output

Returns the converted fiat value for the given crypto amount, the exchange rate used (crypto price in fiat), and the timestamp of the conversion based on the current CoinGecko market price.
