+| Field | Description |
+|---|---|
+| Mode | Fetch mode — `Auto` (default), `Fast` (skips JS rendering), or `JS` (executes scripts) |
+| Stealth | Residential proxy + anti-bot headers. **Adds 5 credits per call** |
+| Country | Two-letter ISO country code for geo-targeted proxy (e.g. `us`, `de`, `jp`) |
+| Wait (Ms) | Milliseconds to wait after page load (0–30000) |
+| Timeout (Ms) | Request timeout in milliseconds (1000–60000) |
+| Scrolls | Number of page scrolls to trigger lazy-loaded content (0–100) |
+| Headers (JSON) | Custom HTTP headers as a JSON object string |
+| Cookies (JSON) | Cookies as a JSON object string |
+
+<Tip>
+Reach for **Stealth** + **Mode = JS** + **Wait = 2000–5000** when a site blocks bots or only renders content after JavaScript runs. Combine with **Country** for region-locked pages.
