Czech Business Register API — Company Search
The Czech Business Register is public and complete, and it is also entirely in Czech, behind a search form that was not designed for machines.
- You send
- A company name or Czech identification number
- You get back
- Structured results from the register's search
- Coverage
- the Czech Republic — entities on the Czech Business Register.
- Price
- 5 pts — $5 per 1,000
- Charged only when the record resolves. A lookup that finds nothing is not billed.
Ways to get this data
Three approaches teams use today, and where each one runs into trouble.
| Approach | What it takes | Cost | Trade-off |
|---|---|---|---|
| the Czech Business Register directly | Use the justice.cz search form and read the results in Czech | Usually free, sometimes per-document | A different interface, language and data shape for every country you add |
| Collecting it yourself | Build and host a crawler per register, then keep each one alive | Infrastructure and maintenance | Registers change their pages without warning, and nobody is on the hook when yours breaks |
| NeuralVerge | One request, the same shape as every other source in the catalog | $5 per 1,000, misses not billed | Covers the Czech Republic — other countries are separate sources with the same request format |
What you get back
Every field the response returns.
| Field | Type | Description |
|---|---|---|
companies | array | Matching entities from the register's search. |
companies[].entity_name | string | Registered name of the entity. |
companies[].ico | string | Czech identification number — the key for any further lookup. |
companies[].file_number | string | Court file number. |
companies[].registration_date | string | Date of registration. |
companies[].address | string | Registered address. |
companies[].full_statement_url | string | Link to the full register extract. |
companies[].documents_url | string | Link to the entity's filed documents. |
Every source answers in the same shape: a session id, a readable human summary, a structured machine object and the points the call consumed. Learn it once and it holds across every source in the catalog.
How to run it
The same lookup works from the app, the API, or as a tool an agent can call mid-task.
A JSON schema passed as extract_schema_json pins the response shape, which is why one endpoint serves every register in the catalog — only the URL and the schema change. The Get API Code button in the app hands you the complete command with the schema already filled in.

the Czech Business Register is a public register. Every response carries the source URL it was read from and a session id you can trace.
- —It returns what the search results page shows, not the full entity file.
- —A common name can return several candidates — the identification number is what disambiguates.
- —The register publishes in Czech.
Questions, answered
The eight-digit identification number assigned to Czech entities. It is the identifier you want out of a search, because it resolves to exactly one entity.
