Quick Start

import { createAnthropic, generateText, streamText } from '@dysporium-sdk/anthropic';

const anthropic = createAnthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
});

// Generate text
const result = await generateText({
  model: anthropic('claude-sonnet-4-5'),
  messages: [{ role: 'user', content: 'Hello!' }],
});

console.log(result.text);

Features

• Full Anthropic API support (Claude 4.5 Sonnet/Haiku/Opus, Claude 4, Claude 3.7, and legacy models)
• Streaming responses
• Tool/function calling
• Automatic retries with exponential backoff
• Full TypeScript support

Usage

Text Generation

import { createAnthropic, generateText } from '@dysporium-sdk/anthropic';

const anthropic = createAnthropic({ apiKey: 'your-api-key' });

const result = await generateText({
  model: anthropic('claude-sonnet-4-5'),
  messages: [
    { role: 'user', content: 'What is the capital of France?' },
  ],
  maxTokens: 100,
  temperature: 0.7,
});

console.log(result.text);
console.log(result.usage); // { inputTokens, outputTokens, totalTokens }

Streaming

import { createAnthropic, streamText } from '@dysporium-sdk/anthropic';

const anthropic = createAnthropic({ apiKey: 'your-api-key' });

const stream = await streamText({
  model: anthropic('claude-sonnet-4-5'),
  messages: [{ role: 'user', content: 'Write a poem about coding' }],
});

for await (const chunk of stream) {
  if (chunk.type === 'text-delta') {
    process.stdout.write(chunk.textDelta);
  }
}

Tool Calling

import { createAnthropic, generateText } from '@dysporium-sdk/anthropic';

const anthropic = createAnthropic({ apiKey: 'your-api-key' });

const result = await generateText({
  model: anthropic('claude-sonnet-4-5'),
  messages: [{ role: 'user', content: 'What is the weather in Paris?' }],
  tools: [
    {
      name: 'get_weather',
      description: 'Get current weather for a location',
      parameters: {
        type: 'object',
        properties: {
          location: { type: 'string', description: 'City name' },
        },
        required: ['location'],
      },
    },
  ],
});

if (result.toolCalls) {
  console.log(result.toolCalls);
}
