Documentation

BoostRail provides an OpenAI-compatible API. If your application already uses the OpenAI SDK, point base_url at the gateway and use a platform key — every model in the catalog becomes available.

Four steps to integrate

Create an account — an organization and project are set up automatically.
Create an API key in the console. The plaintext is shown only once; store it in a secrets manager.
Set base_url and api_key in your SDK or HTTP client.
Make a request. Model names are listed on the Models page, or query GET /v1/models.

Code samples

Python

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.boostrail.com/v1",
)
response = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[{"role": "user", "content": "Hello"}],
    stream=True,
)
for chunk in response:
    print(chunk.choices[0].delta.content or "", end="")

Node.js

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://api.boostrail.com/v1",
});
const completion = await client.chat.completions.create({
  model: "deepseek-v4-pro",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);

curl

curl https://api.boostrail.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "deepseek-v4-pro",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Endpoints

GET /v1/models — list the models available to your account.
POST /v1/chat/completions — chat completions, including stream=true for server-sent events.

Common errors

HTTP status	Error code	Meaning
401	`missing_api_key / invalid_api_key`	No key or a wrong key — check the Authorization header.
403	`disabled_api_key / expired_api_key`	The key is disabled or expired — rotate it in the console.
—	`Insufficient balance`	Requests are rejected without going negative; top up to resume.

Security notes

Never put API keys in frontend code, public repositories, logs, or screenshots. If a key may have leaked, disable it in the console immediately and create a new one.
