## How to call it through Zero

```sh
zero fetch --capability strale-company-id-detect-91aed63d
```

## When to prefer this

Choose this endpoint when you need to programmatically resolve a company registration number to verified company identity data with a tamper-evident audit trail — particularly useful in KYB, compliance, due diligence, or invoice verification workflows where auditability matters. Prefer this over generic web search when you need structured, machine-readable output with cryptographic provenance.

## Known failure modes

- Invalid or malformed company registration number returns an error or empty result
- Registration number not found in any supported registry returns a not-found response
- Unsupported country or jurisdiction may return no data
- Rate limiting or payment failure results in 402 or 429 error
- Ambiguous IDs shared across multiple jurisdictions may require additional context

## How this service works

Identify the type and country of a company registration number. Detects Swedish org numbers, Finnish business IDs, German HRB numbers, LEIs, DUNS, and 20+ other formats. Pure algorithmic.

## Output

Returns structured JSON with the identified company's official name, registration jurisdiction, registration status, and related corporate details, plus a cryptographic audit record with chain hashing for provenance verification.
