Welcome to Portrix — the unified AI gateway that gives you instant access to more than 400 large language models through a single endpoint. Whether you’re building a chatbot, an autonomous agent, or a cost-optimized inference pipeline, Portrix lets you focus on your product instead of managing a sprawl of provider integrations, API keys, and SDK versions.

​
How it works

Getting started with Portrix takes three steps — and if you already use the OpenAI SDK, step two is just a one-line change.
1

Get an API key

Sign up at app.portrix.ai, navigate to Settings → API Keys, and create your first key. One key unlocks every model in the catalog.
2

Point your SDK at Portrix

Set the base URL of your OpenAI-compatible SDK to https://api.portrix.ai/v1 and swap in your Portrix API key. No other code changes are required.
3

Choose any model

Pass the model you want in the model field using the provider/model-name format — for example, openai/gpt-4o, anthropic/claude-3-5-sonnet, or google/gemini-2.0-flash. Portrix handles the rest.

​
Key features

Universal Access

Reach 400+ models from OpenAI, Anthropic, Google, Mistral, and dozens more through a single endpoint, with no extra integrations to maintain.

Drop-in Compatible

Portrix is fully OpenAI-compatible. Point your existing SDK at https://api.portrix.ai/v1 and your current code works without modification.

Smart Routing

Automatic fallbacks, load balancing, and protocol conversion keep your requests flowing even when individual providers experience downtime or rate limits.
