Does registries.io have an API?

Not as at 28 July 2026. Its homepage advertises a JSON API as "coming soon", and no developer documentation is published. If you need to query European company data programmatically today, that is the deciding difference — Prometiam has a live REST API with an OpenAPI spec and an MCP server. Re-check their site before relying on this, since a coming-soon feature can ship at any time.

Which countries does each cover?

registries.io documents six countries with named registers: Austria, Czechia, Germany, the UK, Lithuania and Poland. Its homepage banner states 20 countries, but only those six have registry pages. Prometiam covers six live registries — Spain, France, the UK, Ireland, Poland and Norway — so the only overlap is the UK and Poland.

What does registries.io cost?

It does not publish pricing. Company search is free and a free account unlocks fuller PDF reports; there is no published paid tier. Prometiam publishes every tier: Free at 1,000 calls per month, Starter €9.99, Professional €29.99, Scale €99.99, and custom Enterprise.

Does registries.io do sanctions screening?

No sanctions capability appears anywhere on its site. Prometiam includes screening against five sanctions lists (EU, UN, OFAC, UK OFSI, French gels) plus 11 US export-control lists — 44,000+ active designations, refreshed daily.

Is live registry lookup better than a daily-refreshed database?

It is a genuine trade-off, not a clear win either way. Live lookup means a record is never stale but every query depends on the source registry being up and fast, and bulk or cross-country queries are hard. A daily-refreshed normalized database like Prometiam gives fast search, cross-country joins, historical event timelines and monitoring, at the cost of being up to a day behind the registry.

registries.io Alternative

An honest comparison for teams weighing registries.io against Prometiam. These are products at different stages and of different shapes. registries.io is a web tool for looking up a company and generating a PDF report — directors, ownership and addresses — from official European registries, built by the team behind TransactionLink. As at 28 July 2026 its JSON API is advertised as "coming soon" and is not yet available, and it publishes no pricing. Prometiam is a REST API that is live today, with published pricing and a free tier.

The practical difference right now

If you need to programmatically query European company data today, Prometiam has an API and registries.io does not yet. If you need a human to look up a company and download a report, registries.io does that free, and covers Germany, Czechia, Lithuania and Austria — none of which Prometiam holds.

Where registries.io is genuinely ahead

Poland. Its Poland page lists six linked registers including CRBR (the Polish beneficial-ownership register) and KRZ (the National Register of Debtors). Prometiam serves Polish companies from the KRS but has no Polish directors or UBO — that is a real gap on our side, and we would rather say so than hide it. registries.io also documents Germany, Czechia, Lithuania and Austria, and the England & Wales Charity Register, none of which Prometiam covers.

Where Prometiam is ahead

A live REST API with an OpenAPI spec, an MCP server and published pricing (€0 / €9.99 / €29.99 / €99.99). Six live registries — Spain, France, the UK, Ireland, Poland and Norway — with officers, appointment history and normalized corporate events. Sanctions and US export-control screening across 44,000+ active designations, refreshed daily. Corporate insolvency across nine markets including Germany.

Beyond the registry record

Two derived signals on the Prometiam side, neither of them a rating: registry_compliance, which marks companies still on the register that stopped meeting their filing duties (Spain, the United Kingdom, Ireland and Norway), and public procurement — Spanish contract awards by supplier, buyer, tax id, CPV code and date, plus a beta score for the contracting body itself in Spain and France. Both are dated facts with their source, on the published price and in the free tier; a score is a prompt to look, never a finding of wrongdoing. Public-buyer risk · Procurement screening
