# WebProxyTier

The scraping provider's proxy pools, cheapest first. A page is tried on the cheapest tier that has worked for its host and escalated only when the site blocks or challenges the request; each tier costs more credits than the last.

**Kind:** a string enum, used in responses.

## Values

| Value | Description |
|---|---|
| `"Datacenter"` | Datacenter IPs with a headless browser: fast and cheap, blocked by sites with bot protection. |
| `"Residential"` | Residential IPs with a headless browser, for sites that block datacenter ranges. |
| `"Stealth"` | The provider's stealth mode, for the strongest anti-bot protection. The most expensive tier. |

New values can appear, so treat one you don't know as "something else", not as an error.
