Token Info API: token market cap and liquidity

[TarasBounty]

Is it possible or maybe its a plan to release additional info about token like liquidity + market cap

Token market cap is easy to calculate:

export async function getTokenMarketCap(tokenAddr: string): Promise<{ marketCap: number | null; pricePerToken: number | null }> {
  try {
    // Fetch token supply details
    const tokenSupply = await connection.getTokenSupply(new PublicKey(tokenAddr));
    const decimals = tokenSupply.value.decimals;
    const tokenOneUnit = 10 ** decimals;

    // Fetch price quote from Jupiter
    const response = await axios.get(`${config.JUPITER_HTTP_BASE_URL_PRIMARY}/quote`, {
      params: {
        inputMint: tokenAddr,
        outputMint: WSOL.mint,
        amount: tokenOneUnit,
        slippageBps: 0,
      },
    });

    const outAmount = Number(response.data.outAmount);
    const priceInSol = outAmount / LAMPORTS_PER_SOL;
    const priceInUsd = solToUsd(priceInSol);

    const marketCap = Number(tokenSupply.value.uiAmountString) * priceInUsd;

    return {
      marketCap,
      pricePerToken: priceInUsd,
    };
  } catch (error) {
    console.error(`[getTokenMarketCap] Failed to get market cap for token ${tokenAddr}:`, error);
    return {
      marketCap: null,
      pricePerToken: null,
    };
  }
}

Good sample, thanks!

But what about liquidity? Also it will be perfect to have simple endpoint from @jupiter API

[vscorpio]

I asked in #74 as well, but no response. Your best bet is to determine if you get matched to the highest liquid pair.

Your best bet is to parse first DEX in the route or through direct routes only to force only one DEX and disable multiswap. Using the ammKey and the DEX label, you then call the DEX's SDK to determine liquidity from there.

[TarasBounty]

Yeah, with support they have some issues..

But there can be a big list of DEX'es and I'm not sure that every one have sdk with a free usage :(
