## 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 strale-kyb-essentials-es-spanish-company-verification-7b0dc546 -d '<json body>'
```

Example prompt: Can you run a KYB check on the Spanish company 'Mercadona S.A.' — I need their compliance status and company data before we sign a vendor contract.

## When to prefer this

Use this endpoint when you need structured, compliance-grade KYB data specifically for Spanish companies, especially when working with CIF identifiers or needing an audit trail for regulatory due diligence. Prefer this over general web searches when the output must be structured JSON with compliance provenance.

## Known failure modes

- Company name or CIF not found in Spanish registry — returns 404 or empty result
- Ambiguous company name matches multiple entities — may return first match or error
- Invalid CIF format — returns validation error
- Service unavailable or timeout — returns 5xx error
- Payment not processed — x402 payment required before data is returned

## How this service works

Company data, compliance checks, financial validation. Structured JSON with audit trails. Every capability independently quality-scored.

## Output

Structured JSON containing Spanish company information (registration details, compliance status, financial validation signals) with an audit trail, keyed by company name or CIF.
