Web Data and Document Extraction
Jina Reader
A hosted API that converts any URL into LLM-friendly markdown by adding a prefix, with web search through the same pattern.
Quick decision
- Best for
- Agents and RAG pipelines that need readable page and search content with almost no setup: one URL prefix, no SDK required.
- Not ideal for
- Deep site crawls, complex browser interaction, or schema-driven extraction across thousands of pages. Use a crawler or browser tool for that.
- Pricing model
- The hosted Reader API is free to use within the vendor rate limits, and the code is open source under Apache-2.0 for self-hosting. See the Jina AI site for current limits and any paid tiers.
- Deployment
- Hosted API. Self-hosted Docker.
- Authentication
- The hosted API works without a key for basic use. Follow the vendor docs for keys, rate limits, and header options.
- Review state
- Source verified. Facts checked 2026-10-03. Not locally tested by AgentsUse.
What it does
Jina Reader converts a URL into LLM-friendly input. Prepending https://r.jina.ai/ to a URL returns cleaned content, and https://s.jina.ai/ runs a web search and fetches the top results into the same readable form.
Reader handles web pages through headless Chrome or a lightweight fetch, parses PDFs, converts Office documents, and can caption images for text-only models. Request headers control output format, target selectors, caching, and token budgets.
The hosted API is free to use within its published rate limits, and the repository is the open-source branch behind the service. It can be self-hosted with Docker in stateless mode, with optional bucket caching.
Verified capabilities
Data access
URL to LLM-friendly markdown Source verified
Prepend the Reader prefix to a URL and get cleaned, readable content back.
PDF and Office reading Source verified
PDF URLs are parsed to markdown, and Office documents can be posted for conversion.
Output controls Source verified
Headers select markdown, HTML, text, screenshots, target selectors, and token budgets.
Image captioning option Source verified
A header option captions images so a text-only model gets a hint about each image.
Search and retrieval
Search to markdown Source verified
The search endpoint fetches the top results and returns their content, not just titles and links.
Deployment
Self-host option Source verified
Run the open-source branch with Docker in stateless mode, with optional S3-compatible caching.
Quick start
Fetch one page
The full quick start from the official README. No install and no key for a first call.
curl "https://r.jina.ai/https://example.com"Source: https://github.com/jina-ai/reader. Examples use placeholders only. Never paste a real key into a profile, config file you share, or a ticket.
MCP support: Not claimed here. AgentsUse found no MCP server claim in the checked README, so this profile makes no MCP claim for Jina Reader.
Works with
MCP
No MCP claim verified in the checked source.
API
Hosted HTTPS API (r.jina.ai for reading, s.jina.ai for search). Any HTTP client works.
Packages
No SDK required. Optional self-host runs from the GitHub repository with Docker.
Deployment
Hosted API, or self-hosted Docker.
Only sourced support is listed. A missing framework means AgentsUse has not verified it yet, not that it cannot work.

Limitations and safety
- Hosted rate limits apply. Check the current limits before building a high-volume job on the free path.
- It reads and searches. It does not click through flows, keep sessions, or drive a browser for you.
- No independently checked benchmark is published by AgentsUse for this tool yet.
Browser and data tools can read pages, fill forms, and download files. Start with a test account or read-only access, keep credentials in environment variables, and review agent actions before connecting anything that can spend money, send messages, or delete data.
Alternatives to Jina Reader
Choose Firecrawl when you need site crawls, batch scrape, and structured JSON endpoints behind an API key.
Tradeoff: An account and metered key replace the no-setup prefix call.
Choose Crawl4AI when you want to run the crawler yourself with deep crawl and extraction strategies.
Tradeoff: You install and operate the stack. First value takes longer than a prefix call.
Choose MarkItDown when the input is a local file on disk rather than a live URL.
Tradeoff: No web fetching or search. Files must already be in hand.
