Integration Comparison

OpenRouter Integration
from openai import OpenAI

client = OpenAI(
  base_url="https://openrouter.ai/api/v1",
  api_key="sk-or-..."  # OpenRouter Key
)

response = client.chat.completions.create(
  model="openai/gpt-4o",
  messages=[{"role": "user", ...}]
)
PrivacyProxy Integration
from openai import OpenAI

client = OpenAI(
  base_url="https://api.privacyproxy.dev/v1",
  api_key="sk-..."  # Your OpenAI Key
)

# Same code - PII auto-masked!
response = client.chat.completions.create(
  model="gpt-4o",
  messages=[{"role": "user", ...}]
)

Both are OpenAI compatible. With PrivacyProxy, you only change the base_url - your existing code works immediately.

Frequently Asked Questions

Can I use both together?
Technically yes, but it doesn't make sense. You'd have double latency and costs (User → OpenRouter → PrivacyProxy → Provider). Choose one.
Which is cheaper?
Depends on usage. OpenRouter has token markup (5-20%), PrivacyProxy flat fee (€29-99/mo). At high volume, PrivacyProxy is often cheaper.
Do I need PrivacyProxy if I use EU providers?
Even with EU providers like Mistral, personal data lands on their servers. PrivacyProxy masks BEFORE transmission - that's defense in depth.
Does PrivacyProxy support all OpenRouter models?
PrivacyProxy supports 64 providers directly. You bring your own API keys - giving you access to all models from those providers.
