  "summary": "Prefix-style API from Jina AI that converts any public URL into LLM-ready Markdown (r.jina.ai) or returns web search results with content (s.jina.ai), with open-source server code",
  "description": "Jina Reader is a hosted service from Jina AI with a deliberately minimal interface: prepend `https://r.jina.ai/` to a URL and the response is the page rendered in a headless browser and converted to clean Markdown; prepend `https://s.jina.ai/` to a query and the service returns the top web results with their content in the same format. Headers select output shape (Markdown, JSON, HTML text), fetch engine (direct HTTP or browser rendering), CSS selectors to target or remove, image handling including generated captions, cookies, proxies and cache behavior, and a JSON-schema or instruction header can produce structured extraction using Jina's ReaderLM models.\n\nBasic use needs no key; an API key raises rate limits and switches to token-based metering with a free allowance and purchasable tokens, making the pricing model freemium and usage-based. The server code is published under Apache 2.0, although the ReaderLM models carry a non-commercial license and the hosted service depends on Jina's infrastructure.\n\nIt is a popular building block for agents that need to read a page and for quick corpus construction. Limits: public URLs only, no anti-bot bypass or interactive login, short response caching, and latency of a few seconds when browser rendering is used.",
