(Reply to @glenn - not related to the original issue I think)

Ah - you may have run into the “trailing ‘/’ issue” here.

This has been working for me just fine, but it doesn’t work if I use your URL. However with a tiny modification it works. Your version (I’ve rearranged the curl command / get curl to calculate the header):

```auto
 curl -u MY_API_KEY: 'https://api.companieshouse.gov.uk/search/companies/?q=test&items_per_page=50'
(Gives a 404 and no results)

 curl -u MY_API_KEY: 'https://api.companieshouse.gov.uk/search/companies?q=test&items_per_page=50'
{"items":[{"kind":"searchresults#company",...

```

If you remove the trailing “/” after companies this should work, as in my example.

This is a known issue in _some_ places in the API.

> PSC resource - trailing / causing GET requests to error. We are aware of an issue with the PSC resource which is causing API requests containing a trailing / to be rejected, and we are currently working on a fix. In the meantime, removing any trailing / will allow requests to be made successfully.

We had one bug appear today where if you do a request as such: [https://api.company-information.service.gov.uk/company/123122312/](https://api.company-information.service.gov.uk/company/123122312/) Companies house returns a 500 status code. The fix is to remove the trailing / so [https://api.company-information.service.gov.uk/company/123122312](https://api.company-information.service.gov.uk/company/123122312) This is fine, and an oversight by us however we are trying to ascertain when exactly this c…

BTW I believe the preferred hostname is now:  
[https://api.company-information.service.gov.uk](https://api.company-information.service.gov.uk)

And not:  
[https://api.companieshouse.gov.uk](https://api.companieshouse.gov.uk)

… but both still work.
