# How to interact with Fact Oracle

The PayPerUseOracle contract allows users to access data feeds on a pay-per-use basis. It includes functions to check feed prices, request data, and verify signatures.

Example Usage:

#[program]
mod consumer {
    use super::*;

    // Function to pull data from the Oracle program
    pub fn pull_oracle(ctx: Context<PullOracle>) -> anchor_lang::Result<()> {   
        // Calling the CPI method to get data from the Oracle program     
        let result = oracle::cpi::get_datafeed(
            CpiContext::new(
                ctx.accounts.oracle_program.to_account_info(),                
                GetDataFeed {
                    datafeed: ctx.accounts.datafeed.to_account_info(),
                    subscribers: ctx.accounts.subscribers.to_account_info(),
                    signer: ctx.accounts.signer.to_account_info(),
                },
            ),             
        );

        // Unpacking the result tuple
        let (value, timestamp, confidence) = result?.get();

        // Logging the retrieved data
        msg!("consumer value {} and timestamp {} with confidence {} ", value, timestamp, confidence);

        Ok(())
    }
}
