## 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 ecuadorian-ruc-natural-person-validator-1a065bf2 -d '<json body>'
```

Example prompt: Can you check if this Ecuadorian RUC number 1713175071001 is valid for a natural person?

## When to prefer this

Choose this endpoint when you need a fast, offline-style checksum validation of an Ecuadorian natural person RUC without making external government API calls. Ideal for pre-flight validation before submitting invoices, onboarding freelancers, or KYC workflows involving Ecuadorian individuals. Prefer this over a full government lookup when low latency and no signup overhead matter.

## Known failure modes

- RUC fails checksum validation — returns ok: false
- RUC is not 13 digits — schema validation error
- RUC is valid but belongs to a company, not a natural person — may return ok: false
- Malformed input body — 400-level error
- Payment not included or insufficient — HTTP 402 response
