Wiley API links are not working.

[selcukorkmaz]

I am trying to get the full-text links for Wiley journals using CrossRef API. But, the Wiley links are not working. It simply gives blank page for each link.

http://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fcbic.201300351
http://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fanie.201306302
http://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fcmdc.201300274

Is this because of CrossRef API or Wiley API?

Wiley gives back no content when you aren't authorized, look at the headers in the request. here's an example, which should give you a pdf if you have the right auth:

curl -v -L \
    -H "CR-Clickthrough-Client-Token: <your Crossref TDM click through token>" \
    "http://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fcbic.201300351" > out.pdf

Note that they don't provide XML, so only pdf available.

See https://apps.crossref.org/clickthrough/researchers for getting a click through token

Thanks @sckott! That solved my Wiley problem.

But when I try this:

curl -v -L -H "CR-Clickthrough-Client-Token: <my Crossref TDM click through token>" 
"http://api.elsevier.com/content/article/PII:S0022283615003460?httpAccept=text/xml" > out.xml

I am getting the following error for some Elsevier articles:

<service-error>
    <status>
        <statusCode>ENTITLEMENTS_ERROR</statusCode>
        <statusText>Insufficient entitlements for use with the submitted access key</statusText>
    </status>
</service-error>

Elsevier checks IP addresses (Wiley does too), so you/your institution has to have access to the article. If they do, and you're off campus, you can VPN in (that's what I do).

[selcukorkmaz]

Actually, I am on the campus now (UCSD), and I can access the full text article using Elsevier website. But no luck with the API link.

[sckott]

What do the headers look like? They should have some info

This is the full output I get:

(you should remove your token, unless that's a fake one)

[selcukorkmaz]

I renewed it!

[sckott]

i received the entitlements error a while back, and Elsevier told me:

If you receive an entitlements error on your requests it is likely due to the fact the IP address of the requestor is not associated with an account entitled to access the document.

I'll ask about this and get back to you

[sckott]

no response yet, they may be on vacation now

[selcukorkmaz]

I used the Elsevier API key alongside with the CR-Clickthrough-Client-Token. Now I am getting the abstracts instead of the entitlements error. But, I can't still access the full-text article, even though I am on the campus and I can access the full text article via Elsevier website.

curl -v "CR-Clickthrough-Client-Token: <my Crossref TDM click through token>" 
-k "http://api.elsevier.com/content/article/PII:S0968089609010761?APIKey=
[my Elsevier API key]&httpAccept=text/xml" > out.xml

Hi, we will help to investigate this, but this is probably not the best place to raise issues about publisher platforms. E-mailing support@crossref.org may help, as well as speaking directly to the publishers.

I hope you do not mind if I close this bug down, as really it is not a bug within the REST API.

Ping @afandian in case this is an issue with the TDM click-through service tokens rather than an issue with publishers' usage of those tokens.
