Jina AI offers an API-first integration model. Developers can access embedding, reranking, and URL-to-Markdown conversion endpoints through the Jina AI API. Native integrations are available for MCP (Model Context Protocol), OpenAI-compatible interfaces, and Elastic, allowing the models to slot into RAG orchestration frameworks and search backends. The platform is open source, so self-hosted deployment is supported alongside the managed API. Refer to the official Jina AI documentation for endpoint references, authentication, rate limits, and SDK usage.
