• TypeScript Support: Full TypeScript support with comprehensive type definitions
• Multiple AI Providers: Support for OpenAI, Anthropic, and Google Vertex AI through Crowdin's proxy

Installation

npm install @crowdin/ai-proxy-sdk

Usage

Vercel AI SDK Integration

// OpenAI
import { generateText, streamText } from 'ai';
import { createCrowdinOpenAI } from '@crowdin/ai-proxy-sdk/vercel';

const crowdinOpenAI = createCrowdinOpenAI({
  apiKey: crowdin-api-token, // Crowdin API Token
  providerId: 1234, // Your OpenAI provider ID in Crowdin
  userId: 5678, // Your Crowdin user ID
});

const result = await generateText({
  model: crowdinOpenAI('gpt-5-mini'),
  prompt: 'Hello, how are you?',
});

console.log(result.text);

// OpenAI, stream
const stream = await streamText({
  model: crowdinOpenAI('gpt-5-mini'),
  prompt: 'Tell a short joke.',
});

for await (const textChunk of stream.textStream) {
  console.log(textChunk);
}

// Antropic
import { generateText, streamText } from 'ai';
import { createCrowdinAnthropic } from '@crowdin/ai-proxy-sdk/vercel';

const crowdinAnthropic = createCrowdinAnthropic({
  apiKey: crowdin-api-token, // Crowdin API Token
  providerId: 1235, // Your OpenAI provider ID in Crowdin
  userId: 5678, // Your Crowdin user ID
});

const result = await generateText({
  model: crowdinAnthropic(anthropicModelId),
  prompt: 'Tell a short joke.',
});

// Google Vertex
import { generateText, streamText } from 'ai';
import { createCrowdinGoogleVertexAI } from '@crowdin/ai-proxy-sdk/vercel';

const crowdinGoogleVertex = createCrowdinGoogleVertexAI({
  apiKey: crowdin-api-token, // Crowdin API Token
  providerId: 1236, // Your OpenAI provider ID in Crowdin
  userId: 5678, // Your Crowdin user ID
});

const result = await generateText({
  model: crowdinGoogleVertex('gemini-2.0-flash-001'),
  prompt: 'Tell a short joke.',
});
