How do I properly use curl http post for sending data? or What's the correct syntax for a curl http p

Here’s a pro tip: use `jq` to format your JSON before piping it into curl http post. Less errors! Example:

```bash
echo '{"key":"value"}' | jq . | curl -X POST https://example.com/api -H "Content-Type: application/json" -d @-
```

Also, tools like Postman or Insomnia are great for testing APIs before translating to curl.
