OpenAI-Compatible API — Drop-in /v1/chat/completions
Use an OpenAI-compatible API through ClaudeStore. Point the OpenAI SDK, Cline, Roo Code, Continue, or any custom base URL client at /v1/chat/completions.
Endpoint: POST /v1/chat/completions. Base URL: https://api3.claudestore.store/v1. Models: latest OpenAI models (e.g. gpt-5.5). Works with: OpenAI SDK, Cline, Roo, Continue.
TL;DR
ClaudeStore exposes a standard
/v1/chat/completions endpoint for the OpenAI API. Change the base URL on any OpenAI client and set the model to gpt-5.5 — no code rewrite.Drop-in example
TypeScript (openai SDK)typescript
import OpenAI from "openai";
const client = new OpenAI({
apiKey: "sk-cs4-your-key",
baseURL: "https://api3.claudestore.store/v1",
});
const resp = await client.chat.completions.create({
model: "gpt-5.5",
messages: [{ role: "user", content: "Explain async/await" }],
stream: true,
});Supported
- Streaming (
stream: true) and final usage chunks. - System messages and multi-turn conversations.
- Function / tool calling in OpenAI format.
