Hello,

I tried to connect to an api to return me the USD value of some crypto.  
I would like to use the API provided by [https://www.livecoinwatch.com](https://www.livecoinwatch.com), and I've followed their instruction as per [Live Coin Watch API Documentation](https://livecoinwatch.github.io/lcw-api-docs/?javascript#coinssingle)

I've created several nodes but I can't get this thing to work.  
Of course I've used my actual API key, for the sake of posting I've replaced it with `<MY-API>`

can you please take a look and tell me what I am doing wrong?  
Thank you.

No Idea with the node you're using, but you should be able to use the built in http request node.  
e.g.

```auto
[{"id":"e1db25fcf55f9b7b","type":"inject","z":"c791cbc0.84f648","name":"","props":[{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payloadType":"str","x":90,"y":1200,"wires":[["9f52a5e5ee9f9186"]]},{"id":"9f52a5e5ee9f9186","type":"function","z":"c791cbc0.84f648","name":"Send headers + body","func":"msg.headers = {}\nmsg.headers['content-type'] = 'application/json';\nmsg.headers['x-api-key'] = '<MY-API>';\nmsg.payload = `{\n \"currency\": \"USD\",\n \"code\": \"ETH\",\n \"meta\": true\n}`;\nmsg.url = \"https://api.livecoinwatch.com/coins/single\";\nmsg.method = \"POST\";\nreturn msg;\n","outputs":1,"noerr":0,"initialize":"","finalize":"","x":320,"y":1200,"wires":[["a5ac8be8.c67ea8"]]},{"id":"a5ac8be8.c67ea8","type":"http request","z":"c791cbc0.84f648","name":"","method":"use","ret":"txt","paytoqs":"ignore","url":"","tls":"","persist":false,"proxy":"","authType":"","x":310,"y":1260,"wires":[["b1472595dc5c674a"]]},{"id":"b1472595dc5c674a","type":"debug","z":"c791cbc0.84f648","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":710,"y":1160,"wires":[]}]

It's a home assistant node, so I have no idea as i don't use HA  
But this may help explain it for you  
[https://zachowj.github.io/node-red-contrib-home-assistant-websocket/node/API.html#config](https://zachowj.github.io/node-red-contrib-home-assistant-websocket/node/API.html#config)

> **[REST API | Home Assistant Developer Docs](https://developers.home-assistant.io/docs/api/rest/)**
>
> Home Assistant provides a RESTful API on the same port as the web frontend. (default port is port 8123).
