To get started, obtain an API key from the Jina AI website. The platform offers a token-based pricing model where you can top up tokens as needed. Free tokens are available for non-commercial experimentation without requiring a credit card. The Reader API can be accessed via simple URL patterns like r.jina.ai for reading content and s.jina.ai for web search, making integration straightforward for developers building LLM applications, RAG systems, or search-enhanced products.
