Providers - PasteGuard

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

OpenAI Provider

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

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:

# 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.

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.

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.

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

local:
  type: ollama
  base_url: http://localhost:11434
  model: llama3.2

vLLM

local:
  type: openai
  base_url: http://localhost:8000/v1
  model: meta-llama/Llama-2-7b-chat-hf

llama.cpp

local:
  type: openai
  base_url: http://localhost:8080/v1
  model: local

LocalAI

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:

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
