Hi, I was directed by the enquiries team to post my request here.
I’d like to request an increase to our Companies House API rate limit to 1,200 requests per five minutes, if possible.
My team and I are developing an insolvency information platform that extracts and organises information from Companies House filings. We primarily use the API to download insolvency documents, particularly statements of affairs and administrators’ proposals, alongside accounts filed before or during insolvency proceedings.
We are currently processing a backlog of cases dating back to 2021, which we estimate will take several months under the current rate limit. An increased allowance would help us complete this work sooner.
Our collection process runs requests sequentially, with a 0.5-second delay after each completed API request. Any 429 responses trigger a two-minute pause in the pipeline. All information displayed on our platform comes from our own database, users do not generate Companies House API requests.
We use bulk data products wherever possible. However, the published bulk datasets do not contain the insolvency PDFs required for our extraction process. If a suitable alternative document supply service is available, we would be happy to explore it.
Please let me know if you need any further information about our application or API usage to assess the request.
Thanks!
