This library provides convenient access to the Anthropic Vertex API.

For the non-Vertex Anthropic API at api.anthropic.com, see @anthropic-ai/sdk.

npm install @anthropic-ai/vertex-sdk

import { AnthropicVertex } from '@anthropic-ai/vertex-sdk';

// Reads from the `CLOUD_ML_REGION` & `ANTHROPIC_VERTEX_PROJECT_ID` environment variables.
// Additionally goes through the standard `google-auth-library` flow.
const client = new AnthropicVertex();

async function main() {
  const result = await client.messages.create({
    messages: [
      {
        role: 'user',
        content: 'Hey Claude!',
      },
    ],
    model: 'claude-3-5-sonnet-v2@20241022',
    max_tokens: 300,
  });
  console.log(JSON.stringify(result, null, 2));
}

main();

For more details on how to use the SDK, see the README.md for the main Anthropic SDK which this library extends.
