## 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 latam-datos-api-chilean-rut-validator-d3e43d98
```

Example prompt: Can you check whether the Chilean RUT 12.345.678-9 is valid?

## When to prefer this

Use this endpoint when you need to validate Chilean RUT numbers specifically, especially for KYC flows, invoicing, or any onboarding process requiring Chilean fiscal ID verification. Prefer this over generic regex checks because it implements the actual Chilean modulo-11 check digit algorithm. This endpoint is pay-per-call via USDC micropayment (x402), making it suitable for lightweight agent workflows without subscription overhead.

## Known failure modes

- Missing or malformed 'valor' query parameter returns an error or invalid response
- RUT submitted without check digit may cause unexpected validation logic
- Network timeout from Render.com cold start delays
- Non-Chilean tax IDs (e.g. Argentine CUIT) will not be validated correctly
- Incorrectly formatted RUT strings (e.g. missing dash) may return false negatives
