I will build a custom ai agent with tool calling in nextjs
Asad Ali
About this gig
Need an AI that actually acts instead of just chatting?
I build production-ready tool-calling AI agents for Next.js apps. Your agent can call custom APIs, search the web, manage files, or run multi-step workflows all with real-time streaming and clean TypeScript code.
What You Get:
Multi-step AI agents with custom tool calling (OpenAI, Gemini, Groq)
Clean Next.js + TypeScript codebase using Vercel AI SDK
Streaming chat UI with reasoning and tool feedback
Type-safe validation (Zod), structured outputs & solid error handling
Full source code, walkthrough video, and Vercel-ready setup
How It Works:
1. Scope We define the tools, APIs, and goals
2. Build I design the agent loop, prompts, and schemas
3. Launch We test, refine, and hand over deploy-ready code
Perfect for founders and SaaS builders who want a real agentic layer, not a basic chatbot wrapper. I can start from scratch or integrate directly into your existing Next.js project.
Please message me before ordering so we can discuss your exact needs!

FAQ
What exactly will I receive?
A fully working custom AI agent built with Next.js and the Vercel AI SDK. It includes tool calling (the agent can actually take actions), streaming chat UI, clean TypeScript source code, and a summary so you know how everything works.
Can you work with my existing Next.js project?
Yes. Most of my work is integrating agents into existing codebases rather than starting from scratch. Just share the repo (or relevant parts) and I’ll build on top of it.
Which AI models / providers do you support?
OpenAI, Google Gemini, Groq, and others that work with the Vercel AI SDK. We choose the best one for your use case and budget.
How many tools can the agent use?
Basic package includes 2–3 tools. Standard and Premium go higher. Common tools are web search, API calls, file/document editing, database lookups, etc. We decide together what the agent needs to do.
Do I get the full source code?
Yes, 100%. You own everything I deliver.
Will it be ready to deploy on Vercel?
Yes. I build with Vercel deployment in mind. In higher packages I can also help you get it live.
Can the agent handle multi-step tasks?
Yes — that’s the main difference from a normal chatbot. The agent can plan, call tools in sequence, and continue until the job is done (with sensible limits so it doesn’t run forever).
What do you need from me to start?
A clear description of what the agent should achieve, any existing APIs or data sources, and preferred AI provider (if you have one). A short call helps a lot.
Do you offer ongoing support after delivery?
I include a short handover period. For longer-term help we can discuss a separate arrangement after the order is complete.
I’m not technical — is this still for me?
Yes. I handle the technical side. You just need to explain the outcome you want. I’ll translate that into a working agent.
