OpenAI compatibility

Astrodyne provides an OpenAI-compatible Chat Completions API. Point an existing OpenAI client at the Astrodyne base URL with an Astrodyne key and keep your request and response handling unchanged for the documented scope.

Configuration

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.astrodyne.ai/v1",
    api_key=os.environ["ASTRODYNE_API_KEY"],
)

resp = client.chat.completions.create(
    model="YOUR_MODEL_ID",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.astrodyne.ai/v1",
  apiKey: process.env.ASTRODYNE_API_KEY,
});

const resp = await client.chat.completions.create({
  model: "YOUR_MODEL_ID",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(resp.choices[0].message.content);

Currently supported

• POST /v1/chat/completions — non-streaming and SSE streaming.
• GET /v1/models — the models your key can use.
• Request fields: model, messages, stream, temperature, top_p, max_tokens, max_completion_tokens, stop, presence_penalty, frequency_penalty, tools, tool_choice, response_format, seed, user.
• OpenAI-shape responses, chunks, usage object, and error object.
• Idempotency-Key request header for safe retries of non-streaming requests (see Chat Completions).

Differences to know about

• Model names are Astrodyne canonical IDs. Use the IDs returned by /v1/models rather than assuming another vendor's catalog.
• Unknown request fields are rejected with a 400 naming the parameter, rather than silently ignored.
• Request IDs: every response carries an X-Astrodyne-Request-Id header linking to the Request Explorer.
• Streaming usage is not included in stream chunks; authoritative counts appear in the Request Explorer once the charge is final.

Not currently supported

• Endpoints other than the two above — completions (legacy), embeddings, images, audio, files, batches, and assistants are not available.
• Replaying an Idempotency-Key for a streaming request.
