This demo is fully synthetic and runs in the browser. No real API calls are made.

Why it matters

App stays online

Even during provider outages, your app keeps running. ReliAPI automatically routes to backup services.

Predictable costs

LLM costs remain predictable with budget caps. No surprise bills from runaway API calls.

Automatic reliability

Retry, circuit breaker, and cache happen automatically. You don't need to code resilience yourself.

Integration Examples

Python

import requests

resp = requests.post(
    "https://your-endpoint/proxy/llm",
    json={
        "target": "openai",
        "messages": [
            {"role": "user", "content": "Hello"}
        ]
    }
)
print(resp.json())

JavaScript

const resp = await fetch(
    "https://your-endpoint/proxy/llm",
    {
        method: "POST",
        headers: {"Content-Type": "application/json"},
        body: JSON.stringify({
            target: "openai",
            messages: [
                {role: "user", content: "Hello"}
            ]
        })
    }
);
console.log(await resp.json());
