Verify an EU company: registry coverage by country and plan
cz-agents gives an AI agent or script one EU company registry API and MCP server to search, look up, and verify a company across Europe — national registries where one exists, GLEIF LEI lookup and VIES VAT identity elsewhere. What is unlocked depends on two independent settings: coverage (which countries) and depth (how much due-diligence detail).
Landed here from a tier_required error? That response shape flags a boundary on one of the two axes below. The error's dimension field says which: "coverage" means the country is part of the Extended plan; "depth" means the lookup itself is fine, but the enriched DD+ result is part of the same plan. Either way, Compliance or Agency unlocks both — see pricing below.
Coverage: Core vs Extended
Coverage sets which countries are included in the Core vs Extended tier for a hosted search_company / get_company / lookup_company_by_vat call.
| Tier | Countries | Plan |
|---|---|---|
| Core | GB · CZ · SK · PL · NL | Free, hosted, no signup |
| Extended | AT · BE · DE · DK · EE · ES · FI · FR · IT · LT · NO · SE | Compliance (€99/mo) or Agency (€199/mo) |
Coverage list current as of 2026-07-22 — it mirrors the live country_policies table, so a tier_required error's own available_in_tier field is always the authoritative, up-to-the-minute list; this page is a snapshot of it.
Self-hosting the open-source @czagents/eu-registry server (MIT) removes the coverage gate entirely — the gate only applies to the hosted eu-registry.cz-agents.dev endpoint. GLEIF/LEI and VIES VAT lookups are free and keyless upstream; a handful of national registries need your own API key. See the EU registry MCP server page for exactly which country uses which source.
Depth: basic vs DD+ (ddplus)
Depth is independent of country — it sets how much due-diligence detail a plan includes for a company you can already reach. A Core country like Czechia is included in the free tier to search and verify; the enriched AML/DD report on that same company is part of the paid DD+ tier.
| Tier | Included | Plan |
|---|---|---|
| basic | Company search & lookup, identity verification, VAT/VIES validation, basic Czech DD (ARES + sanctions, no statutory chain) | Free |
| ddplus | Ownership network mapping, nominee/phoenix detection, risk timeline, address crowding, watchlist monitoring, bulk lookup | Compliance (€99/mo) or Agency (€199/mo) |
A depth-dimension tier_required error lists the exact gated tool names in its own available_in_tier field — the categories above are a summary, not the literal list.
DD+ is a closed-source hosted connector — unlike the coverage gate, there is no self-host equivalent for it.
Putting the two axes together
| Request | Coverage | Depth | Plan |
|---|---|---|---|
| Search/verify a UK or Czech company | Core | basic | Free, no signup |
| Search/verify a German or Spanish company | Extended | basic | Compliance/Agency |
| Full AML/DD report on a Czech company (nominee, phoenix, timeline) | Core | ddplus | Compliance/Agency |
| Full AML/DD report on a German counterparty | Extended | ddplus | Compliance/Agency |
Pricing & how to activate
Prices and the full feature/quota comparison live on the pricing page — this page won't duplicate numbers that can drift out of sync. In short:
- Free — Core coverage, basic depth. Self-host on GitHub or use the hosted endpoints, no token needed.
- Compliance and Agency — both unlock Extended coverage and DD+ depth together; Agency adds deeper linked-entity recursion and watchlist monitoring. Subscribe via Stripe checkout on the pricing page, or request a 14-day free trial token (no credit card).
- Custom volume, invoicing, or questions: email [email protected].
tier_required error shape
When a request is outside your plan, the hosted MCP and REST endpoints are built to return a structured error instead of partial data or a silent failure. Here's the shape that error takes once tier enforcement is active:
{
"error": "tier_required",
"dimension": "coverage",
"required_tier": "extended",
"country": "DE",
"country_group": "extended",
"available_in_tier": ["AT","BE","DE","DK","EE","ES","FI","FR","IT","LT","NO","SE"],
"message": "Extended European coverage unlocks lookups for Germany and the rest of the Extended country group — activate it at https://cz-agents.dev/pricing.html.",
"upgrade_url": "https://cz-agents.dev/pricing.html"
}This is the coverage-dimension shape. A depth-dimension error carries the same envelope but an available_in_tier list of ddplus tool names instead of countries.
Tell the agent or script to stop calling the tool, show the user the message, and retry only after upgrading. upgrade_url currently points to the pricing page; this coverage breakdown is one click away from there.
FAQ
- What does a tier_required error mean?
- A
tier_requiredresponse is the shape the hosted EU registry or due-diligence MCP tool uses to flag that a request is outside your plan: either Extended coverage (a country outside the free Core set) or DD+ depth (enriched due-diligence, not basic lookup). Thedimensionfield says which, andupgrade_urlpoints here. - Can I get every country for free?
- Yes, by self-hosting the open-source
@czagents/eu-registryMCP server (MIT license). The coverage gate only applies to the hostedeu-registry.cz-agents.devendpoint; self-hosted code has no country restriction, though some national registries require you to bring your own API key. - What's the difference between coverage and depth?
- Coverage sets which countries are in the Core vs Extended tier. Depth sets how much due-diligence detail a plan includes for a company you can already reach (basic vs DD+ ddplus). The two are independent: a Core country like Czechia is included in the free tier to search, and its full AML/DD report is part of the paid DD+ tier.
- How do I unlock Extended coverage or DD+?
- Subscribe to Compliance (€99/mo) or Agency (€199/mo) on the pricing page, or request a 14-day free trial token. Both plans include Extended coverage and DD+ depth together.
