Hi @Vladlen_Vronsky and @Kamil_Serafin

Try passing your API key as a custom Request Header.

You can do this by adding X-CoinAPI-Key as your header key. You can then insert your API key as your header value.

Let me know if that works!

Even that is not working Daniel. Please find the attachment

I have used the customer header required by the api too. That too didnt work

Hi @Balaji- happy to help!

I took a look at CoinMarketCap’s API documentation and it looks like you’ll need to include either an “id”, “slug”, or “symbol” parameter into the API endpoint URL.

Are you still running into this issue after doing that?
