Try Blendle: https://launch.blendle.com/

Articles cost between $0.10 and $1.15 (most between $0.20 and $0.50). You can request a refund if you don't like an article, which makes the transaction almost frictionless.

The one thing I miss is the ability to share articles without requiring the recipient to sign up for Blendle. Especially since the article can usually be read for free by going directly to the publisher's website. Five or so articles per month to share for free would sound about right.
