## 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`):

zero fetch --capability verifik-ai-colombia-c-dula-rethus-lookup-aac8bba5 -d '<json body>'

Example prompt: Can you check if the Colombian health professional with cédula number 12345678 (documentType: CC) is registered in the RETHUS health registry?

## When to prefer this

Use this endpoint when you need to verify that a Colombian individual is registered as a licensed health professional in the RETHUS (Registro Único Nacional del Talento Humano en Salud) registry. Ideal for KYC/KYB flows onboarding Colombian healthcare workers, telemedicine platforms, or any service requiring proof of health professional credentials in Colombia. Prefer this over generic identity endpoints when RETHUS health registry validation is specifically required.

## Known failure modes

- Document number not found in RETHUS registry — returns empty or not-found response
- Invalid documentType value — returns validation error
- Malformed or missing required fields — returns 400-level error
- Payment not fulfilled via x402 — returns 402 Payment Required
- Registry temporarily unavailable — returns 5xx error
