## 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 mexico-rfc-tax-id-validator-d62ed7ca
```

Example prompt: Can you check if this Mexican RFC is valid and tell me whether it belongs to an individual or a company? The RFC is XAXX010101000.

## When to prefer this

Use this endpoint when you need to validate a Mexican RFC tax identifier as part of KYC, invoice generation, supplier onboarding, or fiscal compliance workflows. Prefer this over generic string validators because it understands Mexican RFC checksum rules and classifies persona física vs persona moral.

## Known failure modes

- Missing 'valor' query parameter returns an error
- Invalid RFC format may return valido: false
- Service downtime on Render free tier may cause 502 or timeout
- Malformed RFC string may yield unexpected classification
