Scored across 2 tools
Both tools involve finding Australian exchanges and comparing pricing/fees, so they overlap in purpose. The descriptions help distinguish them: one targets a best exchange for a specific order, while the other is a broader where-to-buy comparison, but an agent could still call the wrong one.
Both tool names start with find_ and use clear snake_case, which is consistent. The second name uses a 'where_to_buy' clause instead of a simple object noun, so the pattern is mostly consistent with a minor deviation.
Two tools feels thin for an exchange-comparison service, but the scope is narrow and both tools serve related primary use cases. It is borderline rather than clearly excessive or inadequate.
The tools cover the core workflows of finding the best Australian exchange and discovering where to buy crypto. Some possible features like detailed exchange profiles or historical data are missing, but these are minor gaps for the apparent purpose.
Compare Australian exchanges for a cryptocurrency, AUD trade amount, and buy or sell direction. Use find_where_to_buy_crypto for purchase availability. Returns CryptoBuddy API JSON as text; quoted outcomes are estimates and this tool places no exchange order. Paid data access uses XRP on XRPL Mainnet. Call without paymentSignature to obtain an x402 v2 challenge. An authorised compatible payer must create the base64 PAYMENT-SIGNATURE value for that exact resource, then call this tool again with identical trade inputs and that value. Forwarding this value may settle the data-access payment. This server does not create or sign payments. HTTP 402 returns payment requirements; other failures return isError. Do not automatically pay again after a failed or timed-out paid request.
