Oauth tokens, consumer keys, nonces, and timestamps are not something you don't already have access to as a user. The token is your authentication proof / API access key, the consumer key is a bit misleadingly named but just identifies the 3rd party, it is public knowledge. The nonce and timestamps are artifacts of authentication and less sensitive than the token.

The real meat is the 3rd party's consumer secret (the secret key that goes with their consumer key.) If you're finding those then someone needs to make a South Park ski instructor meme.
