Authenthication error API using R software

Post by AlNard » Sat Sep 26, 2020 1:42 am

Dear Open Patent Services Support,
I am trying to use R software to access OPS API and retrieve the text of some patents for my master thesis. However, whenever I try to make a request, even if I still have to make one request, I receive this response:

[2] <message>This request has been rejected due to the violation of Fair Use policy</message>
[3] <moreInfo></moreInfo>

This is the request I make.

response <- POST("https:[slash][slash]ops[dot]epo[dot]org/rest-services/published-data/search/biblio/?q=ti%3Dthermoanaerobacter",
content_type("plain/text"), add_headers("Bearer",

If I use the GET method I receive the same response.

Am I making some mistakes in the response? I should not have exceeded the number of requests because I am still figuring out how to build a query.

Thank you in advance for anyone who might help

It looks like you don't authenticate, either at all, or your authentication has an issue. I hope you are registered to OPS and you have active account, because that can be another reason for rejection?
Please write to us to and we can have a look at your specific issue. Send us your user ID and check first it the account is activated.

Vesna for OPS support
