Choosing a company data API: the criteria that matter

To choose a company data API, compare five criteria: the countries covered, the pricing model (fixed plan or credits), data freshness, monitoring webhooks and the quality of the documentation. This page is the starting point: it links to the detailed eight-criteria guide and to the comparison with the Pappers API.

Frequently asked questions

Which company data API should I choose?+

One that covers your countries, whose price stays readable at ten times your volume, whose data is dated and whose documentation gives an example for every route. Test it on your own use cases before committing.

Fixed plan or credits: which is cheaper?+

Credits cost less for very low usage; a fixed plan becomes easier to read when volume is regular or variable. Work out your monthly volume, then compare it against both price lists.

How many countries does Jsonpage cover?+

14 countries: France, Belgium, Switzerland, United Kingdom, Norway, Finland, Latvia, Ireland, Sweden, Estonia, Lithuania, Australia, Singapore, Japan, with the same response format.

Is there a free plan?+

Yes. The Discovery plan (free) gives access to every route, with 100 requests per minute and 1,000 requests per day, no credit card.
