Jina Reader — URL to LLM-ready text in one HTTP call.

TL;DR — Jina Reader (r.jina.ai) is a free API that converts any URL to clean, LLM-friendly text. Prefix any URL with r.jina.ai/ and get back markdown. Also offers search (s.jina.ai) and grounding (g.jina.ai). Zero setup, no API key required for basic use.

What it is

Jina Reader is a free hosted API that takes any URL and returns its content as clean markdown text. No SDK, no API key for basic usage — just prefix a URL with https://r.jina.ai/ and you get back the page content stripped of navigation, ads, and boilerplate. It also provides a search endpoint (s.jina.ai) that returns web search results as markdown, and a grounding endpoint (g.jina.ai) for fact-checking statements against the web.

Why it exists

Agents need web content in a format they can reason over. Raw HTML is too noisy, and building a scraping pipeline for every URL is overkill. Jina Reader provides the simplest possible interface: one HTTP call, clean text back. No infrastructure, no API keys, no billing for basic usage. It's the "curl for LLMs."

Basic usage — curl

Read any web page as markdown:

# get markdown from any URL
curl https://r.jina.ai/https://example.com/blog/post

# get just the main content (no links, images)
curl -H "X-Return-Format: text" https://r.jina.ai/https://example.com

Basic usage — Python

import requests

url = "https://r.jina.ai/https://docs.python.org/3/tutorial/index.html"
response = requests.get(url)
markdown_content = response.text
print(markdown_content[:500])

For higher rate limits, pass an API key via header: Authorization: Bearer jina_...

Search API

Search the web and get results as markdown — useful for agents that need to search before reading:

import requests

response = requests.get(
    "https://s.jina.ai/what is vLLM PagedAttention"
)
print(response.text)  # markdown-formatted search results

Grounding API

Fact-check a statement against the web:

import requests

response = requests.get(
    "https://g.jina.ai/The Python GIL was removed in version 3.13"
)
print(response.text)  # grounding result with references

Useful for agents that need to verify claims or check if generated content is factually accurate.

When to use, when to skip

Use it when you need quick, zero-setup URL-to-text conversion for agents, RAG ingestion, or content analysis. The search and grounding APIs are great for giving agents web access without managing search API keys.

Skip it when you need to crawl entire sites (use Firecrawl), extract structured data with schemas, interact with pages (use Browser Use), or when you need guaranteed uptime for production workloads (self-host instead).

vs the alternatives

Tool	Best for	Trade-off
Jina Reader	Zero-setup URL→markdown, free tier	No crawling, rate limits on free tier
Firecrawl	Site crawls, structured extraction	API cost, requires API key
BeautifulSoup	Custom HTML parsing logic	No JS rendering, manual work
Tavily	Search API built for agents	Paid, search-focused only
Crawl4AI	Self-hosted LLM-ready crawling	Requires infrastructure
