Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 strale-kyb-essentials-switzerland-99f3e510 -d '<json body>'
```

Example prompt: Can you pull the official Swiss registry data for Nestlé S.A. — I need to verify they're an active registered company in Switzerland and get their UID and registered address?

## When to prefer this

Use this endpoint when you need authoritative, registry-sourced KYB data specifically for Swiss companies (Switzerland / CH jurisdiction). Prefer this over generic business search tools when you need legally reliable data for compliance, onboarding, or due diligence workflows. Best for agents that need structured, auditable company records with cryptographic proof of data provenance. If the company is Austrian, use the Austrian Firmenbuch endpoint instead.

## Known failure modes

- Company not found — name too ambiguous or not registered in Switzerland, returns empty or error
- Invalid UID format — if UID is malformed, returns validation error
- Multiple matches — common company names may match several entities, requiring disambiguation
- Company dissolved — returns data but flags inactive status
- Rate limiting or payment failure — x402 micropayment not processed correctly

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns official Swiss company data including company name, UID, legal form, registration status (active/dissolved), registered office address, canton, founding date, purpose/business description, and names of directors or authorized signatories — all sourced from the official Swiss Zefix/Handelsregister registry, with a cryptographic audit record included.
