Adding Twitter Feed via the API

[devoteappdevelopment]

Hi,
Is it possible to add a twitter "feed" to feedbin via the API? I've tried via the pages:

curl -d '{"url": "https://twitter.com/UKHouseofLords"}' -H "Content-Type: application/json" --user "example@example.com:password" -X POST https://api.feedbin.com/v2/pages.json

and via the subscriptions:

curl -d '{"feed_url": "https://twitter.com/UKHouseofLords"}' -H "Content-Type: application/json" --user "example@example.com:password" -X POST https://api.feedbin.com/v2/subscriptions.json

The former appears to add a page, but it is empty and not listed as a feed. The latter returns a 404 error.

Thanks
