Node.js

The platform is OpenAI-compatible, so use the official openai npm package and change baseURL.

OpenAI SDK

npm install openai

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-your-key",
  baseURL: "https://gateway.mindproxy.ai/v1",
});

const resp = await client.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(resp.choices[0].message.content);

Streaming

const stream = await client.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [{ role: "user", content: "Write a short poem" }],
  stream: true,
});
for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}

Image generation

const img = await client.images.generate({
  model: "gpt-image-1",
  prompt: "a city at night",
  n: 1,
  size: "1024x1024",
});
console.log(img.data[0].url);

Claude (Anthropic SDK)

npm install @anthropic-ai/sdk

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: "sk-your-key",
  baseURL: "https://gateway.mindproxy.ai", // SDK appends /v1/messages
});

const msg = await client.messages.create({
  model: "claude-3-5-sonnet",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Hello" }],
});
console.log(msg.content[0].text);

Passing extra headers

const resp = await client.chat.completions.create(
  {
    model: "gpt-4o-mini",
    messages: [{ role: "user", content: "Hello" }],
  },
  {
    headers: {
      "Idempotency-Key": "my-unique-key-001",
      // "X-TT-Dry-Run": "true",
    },
  },
);

Troubleshooting

• 404: one too many / too few /v1 at the end of baseURL.
• 401: wrong or disabled key.
• Error shapes and status codes: Errors & rate limits.
