WalletWhistle provides product listings, price observations, price-history pages, alerts, and connected read-only tools such as its MCP service.
By using the site or the WalletWhistle MCP endpoint, you agree to these terms.
Last updated: 24 March 2026
WalletWhistle aggregates product and merchant information, records price observations over time, and presents that information to users through the website and connected tools.
The service is informational. It is designed to help users compare prices and track changes, not to guarantee that a merchant will still offer the same item, price, stock level, or promotion when you visit the merchant site.
WalletWhistle may change, suspend, limit, or remove features at any time, including account features, alerts, browse pages, and MCP functionality.
WalletWhistle records prices when they are observed. We do not promise that every price is current at the moment you view it, and we do not control merchant stock, promotions, shipping costs, or checkout terms.
Some outbound merchant links are affiliate links. If you click through or buy, WalletWhistle may earn a commission. That does not change the price you pay, but it does mean commercial relationships may exist behind some tracked offers.
You agree not to misuse the site or MCP service, including by attempting to disrupt it, bypass security controls, overload the service, scrape restricted areas, submit malicious payloads, or use WalletWhistle in a way that violates applicable law or the rights of others.
The WalletWhistle MCP service is intended for read-oriented access to WalletWhistle data. Requests may be logged for diagnostics and security, and access may be rate limited, challenged, or blocked if traffic appears abusive, unstable, or incompatible with the service.
WalletWhistle does not provide financial, investment, legal, or professional advice. Any decision to buy, wait, compare, or rely on a merchant offer is your responsibility.
WalletWhistle is provided on an as-is and as-available basis. To the fullest extent permitted by law, we do not guarantee uninterrupted operation, error-free data, or uninterrupted MCP availability, and we are not liable for losses arising from reliance on price data, merchant changes, outages, or third-party failures.
We may update these terms by posting a revised version on this page. If you have questions about the service or these terms, use the details on the Contact page.
