OpenAI compatibility

Orbit implements OpenAI Chat Completions. Set base_url to Orbit and api_key to your sk-orbit- key. Leave the rest of your code as-is.

Base URL

https://api.tryorbit.cloud/api/v1

The official client appends /chat/completions and /models itself.

Method	Path	Purpose
`POST`	`/chat/completions`	Chat, tools, streaming
`GET`	`/models`	List catalogue models

Auth header: Authorization: Bearer $ORBIT_API_KEY

Examples

Python
Node.js
cURL

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["ORBIT_API_KEY"],
    base_url="https://api.tryorbit.cloud/api/v1",
)

stream = client.chat.completions.create(
    model="gpt-5-6-sol",
    messages=[{"role": "user", "content": "Summarize this diff."}],
    stream=True,
)

for chunk in stream:
    delta = chunk.choices[0].delta.content
    if delta:
        print(delta, end="")

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.ORBIT_API_KEY,
  baseURL: "https://api.tryorbit.cloud/api/v1",
});

const stream = await client.chat.completions.create({
  model: "gpt-5-6-sol",
  messages: [{ role: "user", content: "Summarize this diff." }],
  stream: true,
});

for await (const chunk of stream) {
  const delta = chunk.choices[0]?.delta?.content;
  if (delta) process.stdout.write(delta);
}

curl https://api.tryorbit.cloud/api/v1/chat/completions \
  -H "Authorization: Bearer $ORBIT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5-6-sol",
    "messages": [{ "role": "user", "content": "Summarize this diff." }],
    "stream": false
  }'
