## 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 verifik-ai-colombia-c-dula-rethus-lookup-a3d113eb
```

Example prompt: Can you check if Colombian cédula number 12345678 is registered in the RETHUS health professional registry and verify their credentials?

## When to prefer this

Use this endpoint when you need to verify that a specific Colombian national ID holder is a registered health professional in the RETHUS system. Prefer this over generic KYC endpoints when the use case specifically involves Colombian healthcare worker credential validation.

## Known failure modes

- Cédula not found in RETHUS registry – person is not a registered health professional
- Invalid or malformed cédula number – returns validation error
- RETHUS registry unavailable – upstream timeout or connectivity failure
- Payment not processed – x402 payment required before data is returned
- Rate limit exceeded – too many requests in a short window
