I need a set of AI agents built with the official Claude SDK whose chief role is API integration with other tools. The idea is straightforward: each agent should call the SDK, hit an external service, return the result, and loop that data back into Claude so routine workflows run hands-free. The only non-negotiable component is the Claude SDK itself—please weave it deeply into the design. If you feel that bringing in Google Analytics, Power BI, Tableau, or any other service will strengthen the demo, that flexibility is welcome, but not required right now. Deliverables • Source code for at least two working agents that show full request/response cycles through Claude and an external API • A concise README covering setup, environment variables, and sample calls • Short screencast proving the agents work end to end Acceptance Criteria • Sub-2-second average response for demo calls • Clean, documented code that passes my linting and unit tests on first review • External API base URL changeable in one config file—no edits to core logic If you already have production experience with the Claude SDK, mention a quick highlight or include a thin slice of working code so I can see your approach to streaming responses, function calling, and error handling. I’m ready to start immediately and iterate quickly—let’s chat if you need more technical detail.

Hello, Your project’s focus on seamless API integration using the Claude SDK is critical, especially since it directly impacts efficiency in automating workflows. The need for sub-2-second response times while maintaining clean, documented code presents a strong technical challenge that I am well-equipped to tackle given my experience in API development. To kick off, I would first establish a robust structure for the two AI agents, ensuring that the core logic tightly integrates with the Claude SDK. This will involve setting up the necessary request/response cycles and ensuring flexibility through a configurable external API base URL. I’ll ensure that the source code is organized for easy maintenance and meets your acceptance criteria right from the start. I have hands-on production experience with the Claude SDK, having built similar integrations before—I'd be happy to share relevant snippets demonstrating my approach to handling streaming responses and error management. Do you already have specific external APIs in mind for these agents, or are you open to suggestions based on what might best complement your goals?

Your agents will fail in production if you don't handle Claude's streaming responses correctly—most developers treat the SDK like a simple REST call and miss context window limits that cause mid-conversation crashes. Before architecting this, I need clarity on two things: What's your expected request volume per hour (100 or 10,000 calls matters for rate limiting strategy), and are these agents running synchronously in a user-facing app or async in background jobs? The architecture changes completely depending on your answer. Here's the technical approach: - CLAUDE SDK + FUNCTION CALLING: Implement tool use with streaming responses and token counting to prevent context overflow. I'll build a retry mechanism that handles rate limits (429 errors) and exponential backoff without losing conversation state. - PYTHON ASYNC ARCHITECTURE: Use asyncio with aiohttp for concurrent API calls so one slow external service doesn't block other agents. This keeps your sub-2-second response time even when hitting multiple endpoints. - API ABSTRACTION LAYER: Create a config-driven adapter pattern where each external service (Google Analytics, Tableau, whatever) plugs in through a single interface. Swap base URLs without touching agent logic—just update environment variables. - ERROR HANDLING + OBSERVABILITY: Wrap every external call with timeout guards and structured logging so you can trace failures back to the exact API that broke. I'll include unit tests with mocked responses for both success and failure paths. I've built 4 production Claude integrations in the past 6 months, including one that processes 50K API calls daily for a fintech client. The trickiest part was managing conversation memory across multi-turn interactions—I solved it with a state machine that serializes context between calls. I don't take on projects where performance requirements are vague. Let's jump on a 15-minute call to walk through your actual API endpoints and traffic patterns before I commit to the sub-2-second SLA.

Hi, As per my understanding: You need at least two AI agents built using the Claude SDK that can integrate with external APIs, execute request/response cycles, and loop results back into Claude for automated workflows. The focus is on clean architecture, fast responses, and configurable integrations. Implementation approach: I will build modular agents using the Claude SDK with a clear separation between core logic and external API layers. Each agent will demonstrate full cycles: user input → Claude processing → API call → response parsing → reinjection into Claude. I’ll implement streaming responses, structured function calling, and robust error handling. External APIs (e.g., REST services like analytics or data endpoints) will be configurable via a single config file. Code will be clean, linted, and unit-tested. I’ll include a lightweight demo (CLI or minimal UI) and ensure sub-2s response via async handling and optimized calls. Deliverables will include source code, README, and a short screencast walkthrough. A few quick questions: 1. Do you prefer Node.js or Python for the agents? 2. Any specific external APIs you want included in the demo? 3. Should agents run as CLI tools or lightweight web services? 4. Do you require deployment setup (Docker or cloud) as well?

I implement AI agents using the official Claude SDK to automate workflows through deep integration with external APIs. I will develop two operational agents that perform complete request and response cycles, autonomously processing external data and returning it to the Claude context. I will ensure that each call maintains an average response time of less than two seconds, rigorously adhering to your unit tests and linting standards. I will use the official SDK to manage function calling and error handling, configuring the base URLs in a single file for easy portability. The code will include the necessary support for processing streaming responses, allowing the agents to efficiently and scalably perform hands-free tasks. This structure will allow any external service to be integrated without modifying the core system logic. Do you have a preference for a specific schema validation library, such as Pydantic, to ensure the integrity of the data that the agents send to external APIs? I'll deliver the complete source code, the README file, and the demo screencast within three days. Contact me to define the external services for the demo and begin implementation immediately.

I've been building production workflows with the Claude SDK — streaming responses and tool_use function calling to orchestrate multi-step pipelines. Your sub-2-second response requirement is very achievable with proper async handling. Here's how I'd structure the two agents: • Agent 1: REST API bridge — Claude calls a user-specified endpoint via tool_use, parses the JSON response, and loops the result back into the next Claude turn • Agent 2: Iterative enrichment loop — Claude queries, evaluates if a follow-up call is needed, and terminates with structured output • All config (base URL, API keys, tool schema) in a single .env + config file — zero changes to core logic when switching external services • Deliverables: source code, README with setup/env vars/sample calls, and a screencast proving both agents end-to-end Quick question: Are your external APIs standard REST/JSON, or do you also need GraphQL or WebSocket support in this initial build? Ready to start immediately.

Hi, You need a set of Claude SDK agents wired into external APIs — and the brief cuts off right where the integration targets get interesting. That gap is the first thing worth sorting out before any architecture decisions get locked in. For the build, I'd structure each agent as a focused unit using Anthropic's Python SDK with `tool_use` message payloads — every tool maps to a discrete API action (auth, fetch, transform, write-back). For multi-agent orchestration I'd use a supervisor pattern: `claude-opus-4-6` handles routing and decision logic, while `claude-haiku-4-5-20251001` runs high-volume sub-tasks to keep token costs controlled. Agent configuration lives in a single YAML manifest, so adding a new integration or swapping an endpoint doesn't require touching core logic — just a new entry and a schema definition. What are the specific APIs or platforms each agent needs to integrate with? That one answer lets me produce an accurate scope breakdown and show you exactly how the $12,500 maps across design, implementation, and testing phases. Best regards, Val
