How can I get USD price of a Pumpfun token without using an API?

I am able to get info of a pumpfun token using getAccountInfo on the bonding curve address, but it does not contain the USD price of the token.

This is the code I have so far to get pumpfun token info

export const getPumpfunBondingCurveAccountData = async(wallet: Wallet, mint: PublicKey) => {    const provider = new AnchorProvider(connection, wallet, { commitment: "confirmed" })    const pumpfunProgram = new Program<PumpFun>(IDL as PumpFun, provider)    // get bonding curve PDA    const bondingCurvePDA = PublicKey.findProgramAddressSync(        [Buffer.from(PUMPFUN_BONDING_CURVE_SEED), mint.toBuffer()],        pumpfunProgram.programId    )[0]    const tokenAccount = await connection.getAccountInfo(bondingCurvePDA, "processed")    if (!tokenAccount) {        console.log(`Token account not found for pumpfun token ${mint.toBase58()}`)        return    }    console.log(`Token account owner:${tokenAccount.owner.toBase58()}`)    let bondingCurveAccount = BondingCurveAccount.fromBuffer(tokenAccount.data)    console.log("-- Bonding Curve Account ---")    console.log(bondingCurveAccount)    return bondingCurveAccount}

This outputs an info like the following in the console

Token account owner:6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P-- Bonding Curve Account ---BondingCurveAccount {  discriminator: 6966180631402821399n,  virtualTokenReserves: 936194487413872n,  virtualSolReserves: 34383881167n,  realTokenReserves: 656294487413872n,  realSolReserves: 4383881167n,  tokenTotalSupply: 1000000000000000n,  complete: false}

Is there any way I can get the USD price or USD marketcap of the token from this data?
