Upgraded free and open scholarly API, becoming a Lens partner, new aggregation and citation metrics and more!

Upgraded free and open scholarly API, becoming a Lens partner, new aggregation and citation metrics and more!

N.B. We are no longer supporting Internet Explorer, all other modern and standards compliant browsers are still supported (e.g. Firefox, Microsoft Edge, Chrome, Safari, Opera).

We believe the climate crisis is real and that we need diverse solutions, fast.

We also believe that both the public and private sector will need to partner to create these solutions. And we need the best open information possible for evidence-based problem solving.

So let’s stop erecting artificial barriers that prevent business, civil society, government and academia from freely discovering and mapping partnerships, opportunities, risks and trajectories for products and practices for a better future. While we have always provided the Lens web application for free, and with the confidence that your privacy is assured, we now realise that many institutions have unique in-house data and analysis needs. So we’re dialing it up to 11.  

In this release, Lens.org is pleased to announce version 1.2 of the Lens Scholarly API that will provide free (of both cost and of encumbrance) access for public and private, non-profit and for-profit users (see Lens scholarly API for conditions and to apply for API access). We will release our Lens Patent API under similar conditions soon.

Building on the constructive user feedback from the initial API release, we have expanded API access to provide more flexibility in the way Lens data can be used. If you want to take your API use and participation to a higher level, or you simply value Lens.org as a public service, consider becoming a Partner with the Lens.

Interested in helping us improve?

Become a Lens partner.

There are many contributions that we can discuss together on a case-by-case basis to enable a new generation of problem solvers.

For example, a partner can request and sponsor new Lens functionality, assist in acquiring and accessing new open data, integrate Lens data into their own web applications, share open source code, provide pro bono work, enrich the Lens support content, and promote lens.org by posting tutorials or blog/tweet on the various tools. Several Lens sponsors, in the academic or industrial world, invested non-monetary and monetary resources to help create new features and applications in the Lens, increase transparency to reduce risks and boost confidence in business. You have now an opportunity to do the same.
