# Data Feed Downtime Risk Reference-prices must be reliable in order for the protocol to be able to function properly. This risk can be mitigated when Directors use price oracles that aim to source identical price information from multiple data providers. For example, any oracle reporter can deterministically calculate the market capitalization of an NFT collection’s OpeaSea sales using that collection’s sales history sourced from Dune Analytics, Reservoir Protocol, the OpenSea API, or a custom Subgraph that monitors OpenSea’s smart contract events. Conveniently, when different oracle reporters send deterministic data to the blockchain using different technology stacks, they are also reducing price manipulation risk. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.mimicry.org/whitepaper/risks-and-mitigations/data-feed-downtime-risk.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
