# Cloud APIs Through a Site

> Send OpenAI or Anthropic traffic out through a Pangolin site so the vendor sees a fixed egress IP

Typed [OpenAI](/manage/ai/providers/openai) and [Anthropic](/manage/ai/providers/anthropic) providers send requests from the Pangolin node's own egress. A [Custom](/manage/ai/providers/custom) provider with **Site Targets** sends the same APIs out through a chosen site (Newt), so OpenAI or Anthropic see that site's public IP.

Use this when the vendor allowlists IPs, or all inference must leave from one network. The site is only the egress path. Auth still lives on the provider: paste the real vendor key.

Those typed provider types use **Upstream URL** only. This walkthrough uses Custom plus targets.

See [Capabilities](/manage/ai/providers/configuration#capabilities) for the full capability list.

## Configure

1. Pick a [site](/manage/sites/understanding-sites) that can reach the public internet. That box's public IP is what the vendor will see.
2. Sidebar → **AI Gateway** → **Providers** → **Create**. Set **Provider Type** to **Custom**.
3. Select capabilities that match the cloud API:
   * OpenAI: **OpenAI Chat Completions** and **OpenAI Responses**
   * Anthropic: **Anthropic Messages** and **Anthropic Models**
4. Set **Routing Mode** to **Site Targets**.
5. Set **Auth Type** to **Bearer** for OpenAI, or **`x-api-key`** for Anthropic, and paste the vendor API key.
6. Allow the model ids you plan to call, then save.
7. On the **Network** tab, add a target on that site. Use the API hostname as the address so TLS Host and SNI match:

   | Vendor    | Address             | Port  | Method |
   | --------- | ------------------- | ----- | ------ |
   | OpenAI    | `api.openai.com`    | `443` | HTTPS  |
   | Anthropic | `api.anthropic.com` | `443` | HTTPS  |

   The target address is sent as the Host header.
8. Attach the provider to an [AI Gateway resource](/manage/ai/overview).

The site must resolve and reach that hostname. Clients still point at the resource URL, not at OpenAI or Anthropic directly: [Codex](/manage/ai/configure-ai-clients/codex), [Claude Code](/manage/ai/configure-ai-clients/claude), and the other [client guides](/manage/ai/overview#4-connect-a-client).
