What is Claude API?

Claude API is Anthropic’s programming interface for building Claude language models into your own applications, online shops and business systems. Through the API the model analyses text and documents, generates responses and uses tools defined by the developer, which makes it a foundation for AI agents. Unlike the claude.ai app, it is meant for integration with code rather than conversation in a chat window.

How we use it at Koda Plus

Claude API is part of the stack of an online shop selling consumer electronics, home appliances and garden products, where we deployed an AI customer service agent working in the shop and on Allegro. The same implementation also uses Shopify, BaseLinker, SellAssist and Railway. In our AI agents offer we do not lock clients into one provider – the model is chosen to meet the company’s legal and industry requirements, so Claude API is one of the options rather than a default.

When it makes sense

  • You are building an AI customer service agent on company data
  • Your application needs to analyse long documents or conversations
  • The model should call tools and APIs of your systems
  • AI should work inside an existing shop or admin panel

Frequently asked questions
Claude API

  • What is the difference between Claude API and the Claude app?

    The Claude app (claude.ai) is a ready-made chat for people. Claude API is programmatic access to the models, built into your own software – a shop, a panel or an automation – with your own instructions, tools and control over data.

  • How do I get started with Claude API?

    Create an account in Anthropic’s developer console, generate an API key and call the model from code, most easily through an official SDK, for example for Python or TypeScript. Claude models are also available through cloud platforms such as Amazon Bedrock and Google Cloud Vertex AI.

  • Does Claude API handle languages other than English?

    Yes. Claude models understand and write many languages, including Polish, so they suit multilingual customer service and documents. Before launch it is still worth testing tone and industry terminology on real customer questions, as they show whether the answers sound natural.
