Professional market vault operators produce what is called a Bar List. It's a bit like a bank statement, listing the account holder's stock of bars, and showing both the silver, fine gold, platinum or palladium content of each bar and the total amount of bullion held. We publish the bar lists produced by the vault operators for BullionVault users' bullion. Sparklo will maintain the ownership records of all that bullion. Each day we will publish online our daily register of owners, although we hide your identity by listing your holding against your alias. We also publish the total, and naturally the total matches the total on the bar list. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://sparklo.gitbook.io/sparklo-documents/what-makes-sparklo-different/security.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
