"Open-access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions. What makes it possible is the internet and the consent of the author or copyright-holder.
In most fields, scholarly journals do not pay authors, who can therefore consent to OA without losing revenue. In this respect scholars and scientists are very differently situated from most musicians and movie-makers, and controversies about OA to music and movies do not carry over to research literature.
OA is entirely compatible with peer review, and all the major OA initiatives for scientific and scholarly literature insist on its importance. Just as authors of journal articles donate their labor, so do most journal editors and referees participating in peer review.
OA literature is not free to produce, even if it is less expensive to produce than conventionally published literature. The question is not whether scholarly literature can be made costless, but whether there are better ways to pay the bills than by charging readers and creating access barriers."
-Peter Suber, "A Very Brief Introduction to Open Access"
There are two primary vehicles for delivering OA to research articles: OA journals and OA archives or repositories.

For-profit startup that offers their API to publishers, repositories, and scholars; some uses are free, others (like their Explorer product) cost money. I'd like to highlight their free Bookmarklet, which allows you to view altmetrics for any article. Note: it only works on PubMed, arXiv or pages containing a DOI.
