Keep your code. Change one URL.

DigitSpace accepts the OpenAI Chat Completions API and Anthropic's Messages API, so existing code works by changing the base URL and the API key. Any model can be called in either format; DigitSpace translates between them.

OpenAI SDK

Python, Node.js and any other OpenAI SDK work the same way.

import OpenAI from "openai";

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

const reply = await client.chat.completions.create({
  model: "claude-sonnet-5-5", // any model, in OpenAI's format
  messages: [{ role: "user", content: "Hello" }],
});

Anthropic SDK and Claude Code

Point Anthropic's SDK, or Claude Code, at the gateway without /v1.

export ANTHROPIC_BASE_URL=https://api.digitspace.ai
export ANTHROPIC_AUTH_TOKEN=$DIGITSPACE_API_KEY

Do I need a different SDK?

No. Use the OpenAI or Anthropic SDK you already have.

Can I call a GPT model through the Anthropic API?

Yes. DigitSpace translates the request and the answer, streaming included.

Which tools work with it?

Anything that lets you set an OpenAI-compatible base URL: LangChain, the Vercel AI SDK, LlamaIndex, Cursor, Cline, Aider, OpenCode and more.
