General

OmniaKey is a unified AI model API gateway that lets you access 500+ AI models (GPT-4o, Claude, Gemini, DeepSeek, Llama, etc.) through a single API key. We are fully compatible with the OpenAI API format, so you can switch to OmniaKey by changing just one line of code.
OmniaKey provides several advantages over calling providers directly:
  • Access to 500+ models from all major providers through one API
  • Cost savings — save up to 70% compared to official APIs
  • Multi-provider failover — automatic routing if a provider goes down
  • Unified billing — one invoice instead of managing multiple provider accounts
  • Rate limit management — we handle provider-level rate limits for you
We support 500+ models including GPT-4o, Claude 3.5, Gemini 2.0, DeepSeek V3, Llama 3.3, Mistral Large, DALL-E 3, Stable Diffusion, Sora, and many more. See the Supported Models page for the complete list.
Yes. OmniaKey is a drop-in replacement for the OpenAI API. You can use the official OpenAI SDK for Python, Node.js, Java, or any other language — just change the base URL to https://api.omniakey.com/v1 and use your OmniaKey API key.

​
Billing & Account

OmniaKey uses pay-as-you-go billing. You are charged per token (for chat models) or per image/video (for generation models). There are no monthly fees, no minimums, and no hidden charges.
Yes. You can set monthly spending limits per API key or per account in the Console. When the limit is reached, API requests will return a 429 error until the next billing cycle.
We accept credit cards (Visa, Mastercard, American Express) and wire transfers for enterprise accounts. Payments are processed securely through Stripe.

​
Technical

We offer a 99.9% uptime SLA across all endpoints. Our infrastructure includes multi-provider failover, so if one provider experiences downtime, requests are automatically routed to an alternative.
Rate limits depend on your plan:
  • Free tier: 10 requests per minute
  • Pro tier: 500 requests per minute
  • Enterprise: Custom limits
If you hit a rate limit, the API returns a 429 Too Many Requests error with a Retry-After header.
Yes. All chat completion models support streaming via Server-Sent Events (SSE). Set stream: true in your request to receive partial responses in real-time. See the Chat API docs for examples.
Yes. Function calling and tool use work exactly the same as the OpenAI API. Pass your function definitions in the tools parameter and the model will call them when appropriate.
OmniaKey routes requests through a global edge network. We have points of presence in North America, Europe, and Asia-Pacific to minimize latency.
Yes. We do not store or log your prompt data or model responses. All API traffic is encrypted in transit (TLS 1.3). We are SOC 2 compliant and follow industry best practices for data security.
