Platform Benefits

Cost Effective

Save up to 70% compared to calling official APIs directly. Pay-as-you-go with no hidden fees.

Multi-Provider Routing

Automatic routing across multiple model providers. If one provider is down, your request is seamlessly routed to an alternative — zero downtime, zero code changes.

99.9% Uptime SLA

Enterprise-grade reliability with redundant infrastructure. We monitor every provider in real-time and guarantee 99.9% availability for all endpoints.

Global Edge Network

Requests are routed through our global CDN to the nearest edge node, minimizing latency no matter where your users are located.

Rate Limit Management

We handle rate limits across providers so you don’t have to. Automatic queuing, retry logic, and load balancing are built-in.

Real-Time Monitoring

Track usage, latency, errors, and costs in real-time from the Console. Set up alerts and budgets to stay in control.

​
Quick Example

Get started with any OpenAI-compatible SDK. Just change the base URL: 
from openai import OpenAI

client = OpenAI(
    api_key="your-omniakey-api-key",
    base_url="https://api.omniakey.com/v1"
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum computing in simple terms."}
    ]
)

print(response.choices[0].message.content)
