# Anthropic Messages API — Streaming & Advanced Patterns ## Overview The Messages API is the only inference endpoint. Every Claude interaction goes through `client.messages.create()`. This skill covers streaming, system prompts, vision, and structured output. ## Prerequisites - Completed `clade-install-auth` - Familiarity with `clade-hello-world` ## Instructions ### Step 1: Streaming Responses ```typescript import Anthropic from '@claude-ai/sdk'; const client = new Anthropic(); const stream = client.messages.stream({ model: 'claude-sonnet-4-20250514', max_tokens: 1024, messages: [{ role: 'user', content: 'Write a haiku about TypeScript.' }], }); for await (const event of stream) { if (event.type === 'content_block_delta' && event.delta.type === 'text_delta') { process.stdout.write(event.delta.text); } } const finalMessage = await stream.finalMessage(); console.log('\n\nTokens:', finalMessage.usage); ``` ### Step 2: Vision — Sending Images ```typescript const message = await client.messages.create({ model: 'claude-sonnet-4-20250514', max_tokens: 1024, messages: [{ role: 'user', content: [ { type: 'image', source: { type: 'base64', media_type: 'image/png', data: fs.readFileSync('screenshot.png').toString('base64'), }, }, { type: 'text', text: 'Describe what you see in this image.' }, ], }], }); ``` ### Step 3: JSON / Structured Output ```typescript const message =...
