Add metadata to returned links

[kongzii]

We are currently running a service on our side to fetch article metadata, like og:image and aricle publish time. Is it possible if you guys include this information on the API? There is no rush as we have a solution on our side.

What they currently use:

• https://github.com/SwaprHQ/metadata-api
• https://github.com/SwaprHQ/metadata-api/tree/fly-deploy
