That's a really great suggestion and I feel a bit silly for not having thought of it. (FWIW, there is a test form on the RapidAPI site, but it's more complicated to try and not as fun.) We'll add that. Thank you!
Hi, one of the authors here. We originally built this link preview API for our own apps. (A link preview shows a summary of the page referenced by a URL. Given a link, our API will return the corresponding title, author, publisher, and so on.) Since it worked well for us, we figured why not make it available to everyone?
The reason we decided to build our own (there are several out there) is that we wanted to pull all the data a publisher wanted to share, including all the media, and we wanted it to be fast. Specially, we wanted to edge cache that data as aggressively as possible given the source.
Hopefully, others find this useful. Let us know if there are features you'd like to see. We also launched this on RapidAPI, so let us know if you've had good or bad experience using that platform. This is our first API launch, so we're still figuring out the best way to do this. Thank you!
