GitHub Not Recognizing Passed Client ID and Secret - api

Question

By registering your application you can increase your rate limit for GitHub's API from 60 to 5000 requests[1]. You don't have to use OAuth and can simply pass you're client ID and secret in the URL to have GitHub recognize your application[2]. But when I curl the rate limit check:
curl -i https://api.github.com/ratelimit?client_id=xxx&client_secret=yyy
The following is returned:
HTTP/1.1 200 OK
Server: GitHub.com

Content-Type: application/json; charset=utf-8

X-RateLimit-Remaining: 51

ETag: "[redacted]"
Cache-Control: max-age=0, private, must-revalidate
Vary: Accept-Encoding
{"rate":{"limit":60,"remaining":51,"reset":1373683093}}
Does anyone know what I'm doing wrong? Do I really have to use the full OAuth?

Answer 1

Putting the URL in quotes when running the command fixed the problem.

Answer 2

It's worth noting that you can also register "Personal Access Tokens" from the Applications menu option inside GitHub. This gives you a token with the increased 5,000 API calls/hour without having to do the OAuth dance.
