## 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 toll402-rut-run-validator-0fb4ebe9 -d '<json body>'
```

Example prompt: Can you check if the Chilean RUT '12.345.678-5' is valid?

## When to prefer this

Use this endpoint when you need a quick, no-signup, pay-per-call validation of Chilean RUT/RUN identifiers — especially useful in automated agent workflows processing Chilean user or business data where a lightweight per-call cost model ($0.001 USDC) is preferable to maintaining a subscription or API key.

## Known failure modes

- Invalid or malformed RUT string returns ok: false
- Missing 'rut' field in request body causes a 400-level error
- Incorrect bodyType or method causes request rejection
- Payment failure via x402 returns HTTP 402

## How this service works

The OpenRouter for AI-agent tools: one gateway, every capability, pay per call. Built-in tools, agent-forged tools, a global verified business directory, 2,791 provider API endpoints (SEO, social, enrichment, ads, market data, AI generation) and aggregated x402 services.

## Output

Returns a JSON object with an 'ok' boolean field indicating whether the provided RUT/RUN string is valid (true) or invalid (false), based on format and check digit verification.
