# Providers

> Configure OpenAI, Anthropic, local LLM, and Codex CLI endpoints

Configure endpoints for OpenAI-compatible APIs, Anthropic, local LLMs, and Codex CLI traffic.

## OpenAI Provider

Configure the OpenAI-compatible endpoint for `/openai/v1/*` requests.

```yaml theme={null}
providers:
  openai:
    base_url: https://api.openai.com/v1
    # api_key: ${OPENAI_API_KEY}  # Optional fallback
```

| Option     | Description                                                |
| ---------- | ---------------------------------------------------------- |
| `base_url` | API endpoint (any OpenAI-compatible URL)                   |
| `api_key`  | Optional. Used if client doesn't send Authorization header |

### Compatible APIs

Any OpenAI-compatible API works:

```yaml theme={null}
# OpenAI
providers:
  openai:
    base_url: https://api.openai.com/v1

# Azure OpenAI
providers:
  openai:
    base_url: https://your-resource.openai.azure.com/openai/v1

# OpenRouter
providers:
  openai:
    base_url: https://openrouter.ai/api/v1
    api_key: ${OPENROUTER_API_KEY}

# LiteLLM Proxy (self-hosted)
providers:
  openai:
    base_url: http://localhost:4000

# Together AI
providers:
  openai:
    base_url: https://api.together.xyz/v1

# Groq
providers:
  openai:
    base_url: https://api.groq.com/openai/v1
```

## Anthropic Provider

Configure the Anthropic endpoint for `/anthropic/v1/*` requests.

```yaml theme={null}
providers:
  anthropic:
    base_url: https://api.anthropic.com
    # api_key: ${ANTHROPIC_API_KEY}  # Optional fallback
```

| Option     | Description                                              |
| ---------- | -------------------------------------------------------- |
| `base_url` | Anthropic API endpoint                                   |
| `api_key`  | Optional. Used if client doesn't send `x-api-key` header |

## Codex CLI Backend

Configure the Codex ChatGPT-login endpoint for `/codex/*` requests.

```yaml theme={null}
providers:
  codex:
    base_url: https://chatgpt.com/backend-api/codex
```

| Option     | Description                                                |
| ---------- | ---------------------------------------------------------- |
| `base_url` | Codex backend endpoint for ChatGPT-login Codex CLI traffic |

PasteGuard forwards the Codex CLI `Authorization` header to the Codex backend. Use `/codex` for Codex users signed in with ChatGPT. Use `/openai/v1` only for OpenAI API-key traffic.

## Local LLM

Required for route mode only. Your local LLM for PII requests.

```yaml theme={null}
local:
  type: ollama
  base_url: http://localhost:11434
  model: llama3.2
```

| Option     | Description                                   |
| ---------- | --------------------------------------------- |
| `type`     | `ollama` or `openai` (for compatible servers) |
| `base_url` | Local LLM endpoint                            |
| `model`    | Model to use for all PII requests             |
| `api_key`  | Only needed for OpenAI-compatible servers     |

### Ollama

```yaml theme={null}
local:
  type: ollama
  base_url: http://localhost:11434
  model: llama3.2
```

### vLLM

```yaml theme={null}
local:
  type: openai
  base_url: http://localhost:8000/v1
  model: meta-llama/Llama-2-7b-chat-hf
```

### llama.cpp

```yaml theme={null}
local:
  type: openai
  base_url: http://localhost:8080/v1
  model: local
```

### LocalAI

```yaml theme={null}
local:
  type: openai
  base_url: http://localhost:8080/v1
  model: your-model
  api_key: ${LOCAL_API_KEY}  # if required
```

## API Key Handling

PasteGuard forwards your client's authentication headers to the configured upstream. You can optionally set `api_key` in config as a fallback for OpenAI and Anthropic. Codex CLI traffic uses the CLI's ChatGPT-login authorization header:

```yaml theme={null}
providers:
  openai:
    base_url: https://api.openai.com/v1
    api_key: ${OPENAI_API_KEY}  # Used if client doesn't send auth

  anthropic:
    base_url: https://api.anthropic.com
    api_key: ${ANTHROPIC_API_KEY}  # Used if client doesn't send x-api-key

  codex:
    base_url: https://chatgpt.com/backend-api/codex
```
