# Pa1m SEO – Internationalization (i18n) Category Check

Instantly audits a website's internationalization (i18n) SEO signals — hreflang tags, language declarations, locale targeting, and multilingual best practices — returning a scored JSON result.

## 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 pa1m-seo-internationalization-i18n-category-check-942ecda7
```

Example prompt: Can you run a quick i18n SEO check on mywebsite.com and tell me if the hreflang tags and language targeting are set up correctly for international search?

## When to prefer this

Use this endpoint when you need a fast, single-category i18n SEO check without running a full-site audit. Ideal for quickly validating hreflang implementation, language targeting, and multilingual SEO signals on a known URL. Prefer this over /scan/full when you only care about internationalization issues and want an instant result at lower cost ($0.05 vs a full scan).

## Known failure modes

- Missing required 'url' query parameter returns a validation error
- Unreachable or non-existent target URL may return an empty or error result
- Sites behind bot-blocking firewalls may yield incomplete audit data
- Payment not fulfilled (402) blocks access if USDC payment is not processed
- Rate limiting or timeout if the target page loads very slowly

## How this service works

SEO audit any website — 200 rules across 20 categories: technical health, Core Web Vitals, content quality, AI-GEO signals, accessibility, security headers, structured data, and more. Async job flow: POST /scan/quick or /scan/full → poll GET /status/{job_id} → get JSON result with per-category scores (0–100) and issue lists. Use /brief for an AI action plan, /analyze for free-form SEO questions, or /check/{category} for instant single-category audits.

## Output

A JSON object with a category field set to 'i18n' and a result object containing a score from 0–100 for internationalization SEO, along with a list of detected issues such as missing or conflicting hreflang tags, incorrect language declarations, missing x-default annotations, and locale targeting misconfigurations.
