Company register access by country
Does a country’s official company register have a search, an API, a key, a price, a rate limit or a bulk download? One dated row per country, with a link to what Prometiam serves there.
How to read the table
Every row repeats the dated answer on that country’s guide (“Is there an official ... API?”), read on the register’s or the authority’s own site. Not stated means the page we read does not say; Not checked means we have not read that column for the country. Access terms change: check the register’s own page before you build on a row. Where a row says what Prometiam serves, the country’s scope limits are part of the row.

Live countries not yet checked
These countries are served by the API but their register access has not been read for this page, so there is no row and no guess. Each guide states what Prometiam serves there.
One key instead of one integration per register
Each register above has its own format, identifier, terms and limits. Prometiam returns the same company object for every live country through one REST API, with monitoring on top; a company search, record or lookup item costs 1 credit. The company data API guide explains the object; free company data API covers what the open registers give you for nothing.
Starter is EUR 9.99 a month with 1,000 credits, and it is the plan with the 14-day trial: 500 credits, card required, nothing charged during the trial.
