Ship an AI Agent with Claude
Build a research agent that searches the web, summarizes articles, and compiles reports — deployed as a REST API.
All steps
01Step 1: What We're BuildingA research agent powered by Claude that can search the web, summarize articles, extract key facts, and compile reports — deployed as a REST API with FastAPI.→02Step 2: Project SetupCreate the Python project, install dependencies, and configure your Anthropic API key.→03Step 3: Basic Claude CallMake your first Claude API call, understand the message format, and set up a system prompt for your research agent.→04Step 4: Define ToolsDefine three tools — web search, calculator, and save note — using Claude's tool-use format so the model can take real actions.→05Step 5: The Agent LoopBuild the core agent loop — the engine that sends messages to Claude, detects tool calls, executes them, and loops until Claude has a final answer.→06Step 6: Web Search ToolReplace the placeholder web search with a real implementation using DuckDuckGo so your agent can find current information — no API key required.→07Step 7: Memory and ContextAdd conversation history and context management so your agent can handle multi-turn research sessions without losing track of earlier findings.→08Step 8: Deploy as APIWrap your research agent in a FastAPI server with streaming support so any application can use it.→09Step 9: What's NextProduction hardening — add error handling, guardrails, rate limiting, and learn how to scale your agent for real-world use.→
