Please note that this oracle utilizes data from a custom API source belonging to ProsperaVest ESG. DIA does not guarantee the accuracy of this data or the uptime of the feed, as it is subject to potential downtimes or inconsistencies from the ProsperaVest API source.

Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below: ### Oracle The oracle is deployed and can be accessed [here](https://polygonscan.com/address/0x466445a9d52b2bdcd934379b6bd832061b12db00). You can query for assets by calling the read function getValue() with parameters such as “NGN/USD”. It will return two values: 1. The price of the asset queried with 8 decimals 2. The unix timestamp of the last update You can see Solidity and Vyper code integration examples [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#oracle-integration-example) or use a dedicated DIA oracles integration library described in detail [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#accessing-dias-oracles-with-a-dedicated-solidity-library). ### Funding Each deployed oracle contract has a separate gas wallet which is the only entity allowed to update oracle values based on selected parameters. To find out more information on how it works, visit the following [link](https://docs.diadata.org/introduction/intro-to-dia-oracles/oracle-funding). Please make sure to top up the gas wallet, as we only put in some gas to deploy and start the oracle. Gas Wallet address: [0x7f8a2583d9d9545b0dc84cc5432d37edbd2e16ef](https://polygonscan.com/address/0x7f8a2583d9d9545b0dc84cc5432d37edbd2e16ef) ### Source The source is the one specified in the request. Please note that the oracle uses the first value from the "values" array from the API endpoint.
