# I Will Build a Custom AI Agent Using OpenAI or Google ADK

If your business is ready to harness the real power of AI automation, a custom-built intelligent agent is one of the most impactful investments you can make. This service delivers production-ready AI agents built on two of the most capable frameworks available today: OpenAI Agent SDK and Google ADK — engineered to reason, plan, act, and communicate on your behalf.

Whether you need a simple agent to handle a specific task quickly, or a fully integrated solution connected to your CRM, WhatsApp, Slack, or WordPress site, this service scales to match your ambition. Every agent is built by a London, England-based team with hands-on experience across a wide range of industries and use cases.

\*\*What You Can Build\*\*
 From customer support bots and lead qualification agents to appointment booking assistants, phone call automation, and multi-platform messaging integrations — the possibilities are broad. Agents can be connected to your existing databases, APIs, and third-party services to enable real-time data retrieval and intelligent decision-making. Voice calling, WhatsApp, and Slack integrations are all within scope. Need something bespoke? Custom workflows, complex API chains, and cross-platform communication can all be discussed via the order chat.

\*\*How It Works\*\*
 Once your order is placed, share your project requirements through the order chat. The more detail you provide — your platform, your goals, your existing tools — the faster work can begin. If anything is unclear, the team will follow up directly. You will receive your agent as deliverable code or a deployment-ready package, depending on the agreed scope.

\*\*Frameworks & Flexibility\*\*
 Both OpenAI Agent SDK and Google ADK are cutting-edge agent frameworks designed for reliability and extensibility. If you have existing pretrained models or proprietary datasets, those can be incorporated. If you need an OpenAI API key and are unsure how to obtain one, guidance is available.

\*\*Who This Is For\*\*
 This service is ideal for business owners, product managers, developers, and startups who want to automate workflows, improve customer interactions, or explore AI-driven experiences — without needing to build everything from scratch themselves. It suits e-commerce, healthcare, finance, and virtually any sector that benefits from intelligent automation.

\*\*Why Zinn Digital\*\*
