Quick Start

Quick Start

Each provider requires two changes: set the base URL to the Xybern proxy, and add your Xybern API key as a header. Your original provider API key passes through unchanged.

OpenAI SDK

from openai import OpenAI

client = OpenAI(
    api_key="sk-...",           # your real OpenAI key — passed through
    base_url="https://www.xybern.com/gateway/openai",
    default_headers={"X-Xybern-API-Key": "xb_live_..."},
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello"}],
)

OpenAI environment variables (works with any OpenAI-compatible framework)

OPENAI_BASE_URL=https://www.xybern.com/gateway/openai
OPENAI_DEFAULT_HEADERS='{"X-Xybern-API-Key": "xb_live_..."}'

LangChain

from langchain_openai import ChatOpenAI

llm = ChatOpenAI(
    model="gpt-4o",
    openai_api_key="sk-...",
    openai_api_base="https://www.xybern.com/gateway/openai",
    default_headers={"X-Xybern-API-Key": "xb_live_..."},
)

Anthropic SDK

import anthropic

client = anthropic.Anthropic(
    api_key="sk-ant-...",
    base_url="https://www.xybern.com/gateway/anthropic",
    default_headers={"X-Xybern-API-Key": "xb_live_..."},
)

Azure OpenAI

from openai import AzureOpenAI

client = AzureOpenAI(
    api_key="your-azure-key",
    azure_endpoint="https://www.xybern.com/gateway/azure",
    api_version="2024-02-01",
    default_headers={
        "X-Xybern-API-Key": "xb_live_...",
        "X-Azure-Upstream": "https://<your-resource>.openai.azure.com",
    },
)

AWS Bedrock (boto3)

import boto3

bedrock = boto3.client(
    service_name="bedrock-runtime",
    region_name="us-east-1",
    endpoint_url="https://www.xybern.com/gateway/bedrock/us-east-1",
)

# Pass AWS credentials + Xybern key via custom headers using a botocore event:
def inject_xybern_key(request, **kwargs):
    request.headers["X-Xybern-API-Key"] = "xb_live_..."

bedrock.meta.events.register("before-send.bedrock-runtime.*", inject_xybern_key)

Google Gemini (OpenAI-compatible endpoint)

from openai import OpenAI

client = OpenAI(
    api_key="AIza...",          # your Google API key
    base_url="https://www.xybern.com/gateway/gemini/openai",
    default_headers={"X-Xybern-API-Key": "xb_live_..."},
)

response = client.chat.completions.create(
    model="gemini-2.0-flash",
    messages=[{"role": "user", "content": "Hello"}],
)
