I have built an API to retrieve Companies House IXBRL accounts in json and excel format

1

Hi all

I have built [https://convert-ixbrl.co.uk/](Convert companies house IXBRL accounts to JSON) which is a JSON API and a search portal to look up UK companies based on financial metrics and also download balance sheet, profit & loss and cash flow statements(where available in IXBRL), either through the API or using the web interface.

I’ve used the companies house bulk accounts data product for this.

Using the api or the website , companies can be looked up using netassets, turnover, employees, cash, location, industry and incorporation date

It’s currently free (and I’d like to keep it free if I can, hopefully by offering optional add on paid services such as credit reports to the web portal users) but I’m subsidising the cost of running the infrastructure using some of the revenue from a different side project.

You can try it out on convert-ixbrl.co.uk above. No registration needed. If you have any questions, send me a DM here or see my contact details on the website.

Here is the API docs page API documentation but all the functionality that the API provides is also available through the web interface.

Thanks

I get a 400 “Invalid credentials - API Secret header is missing” response when I included the test mode authentication request header.

Thanks for trying the API Paul. Probably best to send a short email or whatsapp message to me using the contact form on contact IXBRL-converter . Both the test and live credentials should work though.
