Authentication

How to authenticate your API requests

Requests under /v1 and /v1beta need an API key. Create an account on the home page. Generate an API key on the Keys page.

The public status endpoints and the public model list need no API key. See Overview and OpenAI Style for details.

API Key Security

SilentAPI stores API keys as hashes. Treat your API keys like passwords. Do not commit them to version control. Do not put them in browser code or logs.

Sending Your Key

Send your API key in a supported header. Query parameters are available for clients that require them.

Authorization Header (Recommended)

Authorization: Bearer YOUR_API_KEY

This works with the OpenAI SDK, the Anthropic SDK, curl, and most HTTP libraries.

x-api-key Header

x-api-key: YOUR_API_KEY

The Anthropic SDK sends the x-api-key header. All authenticated API endpoints accept it.

x-goog-api-key Header

x-goog-api-key: YOUR_API_KEY

The Google GenAI SDK sends the x-goog-api-key header. All authenticated API endpoints accept it.

Query Parameter

https://api.silentapi.com/v1/chat/completions?apiKey=YOUR_API_KEY

https://api.silentapi.com/v1/chat/completions?key=YOUR_API_KEY

Use a query parameter only when a client cannot set a header.

SDK Examples

OpenAI SDK (Python)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.silentapi.com/v1"
)

response = client.chat.completions.create(
    model="gpt-6-sol",
    messages=[{"role": "user", "content": "Hello"}]
)
print(response.choices[0].message.content)

OpenAI SDK (JavaScript)

import OpenAI from "openai";

const client = new OpenAI({
    apiKey: "YOUR_API_KEY",
    baseURL: "https://api.silentapi.com/v1"
});

const response = await client.chat.completions.create({
    model: "gpt-6-sol",
    messages: [{ role: "user", content: "Hello" }]
});
const responseText = response.choices[0].message.content;

Anthropic SDK (Python)

import anthropic

client = anthropic.Anthropic(
    api_key="YOUR_API_KEY",
    base_url="https://api.silentapi.com"
)

message = client.messages.create(
    model="claude-sonnet-5.5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello"}]
)
print(message.content[0].text)

Google GenAI SDK (Python)

from google import genai

client = genai.Client(
    api_key="YOUR_API_KEY",
    http_options={"base_url": "https://api.silentapi.com"}
)

response = client.models.generate_content(
    model="gemini-3.8-flash",
    contents="Hello"
)
print(response.text)

Per-Key Budgets

Set a monthly credit budget on each API key on the Keys page. Requests with that API key return HTTP 402 when its budget is reached.
