## 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 polls-karbach-digital-german-lobby-register-entry-lookup-20154de8
```

Example prompt: Can you pull up the full German lobby register entry for R001234? I want to see the organization details, their registered lobbying activities, and any financial disclosures listed.

## When to prefer this

Use this endpoint when you have a specific German lobby register number (R######) and need the complete, authoritative entry for that registrant. Prefer this over search-based endpoints when the register number is already known. Ideal for compliance checks, journalism, academic research, or transparency tools that need structured, source-attributed German lobbying data updated every six hours.

## Known failure modes

- Invalid register number format (must match R followed by exactly 6 digits) returns a validation error
- Register number not found in the database returns a 404-style error
- Temporary data freshness gap if the register was updated within the last six hours and sync has not yet completed
- Payment failure via x402 protocol prevents access to the response
