## 2. Public API Surface & Endpoints

Base URL: `https://brante.dev`

### Health Probe
- **Path:** `GET /api/v1/health` (or `GET /api/health`)
- **Status:** `200 OK`
- **Output:**
  ```json
  {
    "status": "ok",
    "version": "1.0.0",
    "timestamp": "2026-09-01T17:00:00.000Z"
  }
  ```

### WPO Diagnostic Endpoint
- **Path:** `POST /api/v1/diagnostico`
- **Headers:** `Content-Type: application/json`
- **Body:** `{"url": "https://target-site.cl"}`
- **What it returns:** a real mobile measurement from Google PageSpeed Insights. `performanceScore` is the Lighthouse lab score (0-100), the number behind «PageSpeed 90+». Core Web Vitals (LCP, INP, CLS) come from Chrome UX Report field data and are judged against thresholds (`passed`, `failed` or `insufficient-data`); there is no 0-100 Core Web Vitals score.
- **Response Example** (illustrative values):
  ```json
  {
    "url": "https://target-site.cl/",
    "performanceScore": 87,
    "lab": { "lcp": "2.9 s", "cls": "0.02", "tbt": "150 ms", "fcp": "1.4 s", "speedIndex": "3.1 s" },
    "coreWebVitals": { "assessment": "insufficient-data", "scope": null, "lcpMs": null, "inpMs": null, "cls": null },
    "opportunities": ["Serve images in next-gen formats", "Eliminate render-blocking resources"]
  }
  ```

### Error Protocol (RFC 9457)
All error responses adhere to Problem Details (`application/problem+json`):
```json
{
  "type": "https://brante.dev/errors/invalid-parameter",
  "title": "Invalid Parameter",
  "status": 400,
  "detail": "Target URL is invalid or unreachable.",
  "code": "ERR_INVALID_URL"
}
```

## 3. Rate Limits & Headers

Cloudflare enforces the limit per IP on every `/api/` route: 30 requests every 10 seconds. Responses state it:
- `RateLimit-Limit`: 30 (requests per window).
- `RateLimit-Policy`: `30;w=10` (30 requests every 10 seconds).
- `RateLimit-Reset`: 10 (window length in seconds).
- There is no `RateLimit-Remaining`: the count is kept by Cloudflare, not by the API.
- `Retry-After`: Returned on HTTP 429.
