Is there an API for Companies House?

Companies House does not offer a public data API for this, but Anakin Wire provides 5 maintained endpoints for companieshouse.gov.uk. You call Anakin's REST API with an action ID and parameters and get structured JSON back; Anakin handles the browser, proxies, anti-bot, and parsing.

How do I scrape Companies House data?

POST to https://api.anakin.io/v1/wire/task with your API key, the action ID, and its parameters, then poll GET /v1/wire/jobs/{id} until the job settles. There is nothing to install and no scraper to maintain — when companieshouse.gov.uk changes its markup, Anakin updates the action.

Do I need a Companies House account?

No. Every Companies House action listed here runs anonymously — no account and no credentials required.

What does the Companies House API cost?

Usage-based credits, charged per call and refunded automatically when a job fails. New accounts start with 300 free credits and no card. See anakin.io/pricing for the current rates.
