Overview
Jsonpage is a fixed-price company data API, published by Devintech. It returns the company record in one JSON format for 14 countries: France, Belgium, Switzerland, United Kingdom, Norway, Finland, Latvia, Ireland, Sweden, Estonia, Lithuania, Australia, Singapore, Japan. The data comes from the official registers. No credits, no monthly quota, no overage billed.
What the service does:
- Look up a company by identifier or by name, with one global identifier per company (country code, hyphen, national number).
- Autocomplete and validation for forms: identifier, SIRET and VAT number in one call.
- Verified VAT number with its status, legal notices, insolvency signals and indicative sanctions screening.
- Monitoring: every change becomes an event, delivered by signed webhook and by e-mail. A separate offer cleans customer files before e-invoicing.
