## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-eu-company-search-e897963b
```

Example prompt: Can you search the European company registers for 'Equinor ASA' — check Norway and any other available countries — and tell me its national company ID and current status?

## When to prefer this

Use this endpoint when you need to search for European companies by name across multiple official national registers simultaneously, especially when the user is uncertain which country the company is registered in, or when you need GLEIF/LEI coverage for financial entities and large groups. Prefer this over country-specific endpoints when the target country is unknown or when pan-European coverage is required.

## Known failure modes

- No matches found for the given company name (empty results list)
- Country filter value not recognized (invalid ISO-3166 code)
- Missing required query parameter 'q' (400 error)
- Service temporarily unavailable for a specific national register
- Payment not processed correctly (x402 payment required error)

## How this service works

European company search across official registers: company lookup by name, returning European company data in one unified schema. Norway, Estonia, Latvia and Spain (BORME base, hoja key) are served from local copies; Czechia, Slovakia, Finland, Poland and Switzerland are queried live; Denmark and UK when enabled; plus worldwide GLEIF (LEI) coverage of financial entities and large groups. Top 10 matches with country, national ID, status and a score_confiance (0-1 match confidence).

## Output

Returns top 10 matching companies from official European registers (Norway, Estonia, Latvia, Denmark, UK, GLEIF), each with the company's name, country, national registration ID, and current status.
