### `find_best_australian_exchange`

- The name "find_best_australian_exchange" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare Australian cryptocurrency exchanges to identify the best estimated buying or selling outcome for a specified asset, AUD trade amount and direction. Use this tool when the user wants to compare exchange prices, fees or estimated value received. For simply finding exchanges that offer a cryptocurrency, use find_where_to_buy_crypto instead. Results are estimates, not guaranteed executable quotes, and no trade is placed. This is a paid data-access tool using XRP on XRPL Mainnet. First call without paymentSignature to receive an x402 v2 payment challenge. An authorised compatible payer must generate the PAYMENT-SIGNATURE for the exact resource and retry with identical inputs. Never supply wallet secrets. This server does not sign or initiate payments. If payment fails or times out, verify settlement before attempting another payment.
```
