What is Reader?

Feeding web information into LLMs is an important step of grounding, yet it can be challenging. The simplest method is to scrape the webpage and feed the raw HTML. However, scraping can be complex and often blocked, and raw HTML is cluttered with extraneous elements like markups and scripts. The Reader API addresses these issues by extracting the core content from a URL and converting it into clean, LLM-friendly text, ensuring high-quality input for your agent and RAG systems.
Raw HTML
Reader Output

Reader for web search

Reader allows you to feed your LLM with the latest information from the web. Simply prepend https://s.jina.ai/ to your query, and Reader will search the web and return the top five results with their URLs and contents, each in clean, LLM-friendly text. This way, you can always keep your LLM up-to-date, improve its factuality, and reduce hallucinations.
info Please note that unlike the demo shown above, in practice you do not search the original question on the web for grounding. What people often do is rewrite the original question or use multi-hop questions. They read the retrieved results and then generate additional queries to gather more information as needed before arriving at a final answer.

Reader for fact-checking

The new grounding endpoint offers an end-to-end, near real-time fact-checking experience. It takes a given statement, grounds it using real-time web search results, and returns a factuality score and the exact references used. You can easily ground statements to reduce LLM hallucinations or improve the integrity of human-written content.

Reader also reads images!

Images on the webpage are automatically captioned using a vision language model in the reader and formatted as image alt tags in the output. This gives your downstream LLM just enough hints to incorporate those images into its reasoning and summarizing processes. This means you can ask questions about the images, select specific ones, or even forward their URLs to a more powerful VLM for deeper analysis!

Reader also reads PDFs!

Yes, Reader natively supports PDF reading. It's compatible with most PDFs, including those with many images, and it's lightning fast! Combined with an LLM, you can easily build a ChatPDF or document analysis AI in no time.

The best part? It's free!

Reader API is available for free and offers flexible rate limit and pricing. Built on a scalable infrastructure, it offers high accessibility, concurrency, and reliability. We strive to be your preferred grounding solution for your LLMs.
Rate Limit
Rate limits are tracked in two ways: RPM (requests per minute) and TPM (tokens per minute). Limits are enforced per IP and can be reached based on whichever threshold—RPM or TPM—is hit first.

Other questions

Reader-related common questions
What are the costs associated with using the Reader API?
keyboard_arrow_down
The Reader API is free of charge and does not require an API key. Simply prepend 'https://r.jina.ai/' to your URL.
How does the Reader API function?
keyboard_arrow_down
The Reader API uses a proxy to fetch any URL, rendering its content in a browser to extract high-quality main content.
Is the Reader API open source?
keyboard_arrow_down
Yes, the Reader API is open source and available on the Jina AI GitHub repository.
What is the typical latency for the Reader API?
keyboard_arrow_down
The Reader API generally processes URLs and returns content within 2 seconds, although complex or dynamic pages might require more time.
Why should I use the Reader API instead of scraping the page myself?
keyboard_arrow_down
Scraping can be complicated and unreliable, particularly with complex or dynamic pages. The Reader API provides a streamlined, reliable output of clean, LLM-ready text.
Does the Reader API support multiple languages?
keyboard_arrow_down
The Reader API returns content in the original language of the URL. It does not provide translation services.
What should I do if a website blocks the Reader API?
keyboard_arrow_down
If you experience blocking issues, please contact our support team for assistance and resolution.
Can the Reader API extract content from PDF files?
keyboard_arrow_down
Yes, the Reader API can natively extract content from PDF files.
Can the Reader API process media content from web pages?
keyboard_arrow_down
Currently, the Reader API does not process media content, but future enhancements will include image captioning and video summarization.
Is it possible to use the Reader API on local HTML files?
keyboard_arrow_down
No, the Reader API can only process content from publicly accessible URLs.
Does Reader API cache the content?
keyboard_arrow_down
If you request the same URL within 5 minutes, the Reader API will return the cached content.
Can I use the Reader API to access content behind a login?
keyboard_arrow_down
Unfortunately not.
Can I use the Reader API to access PDF on arXiv?
keyboard_arrow_down
Yes, you can either use the native PDF support from the Reader (https://r.jina.ai/https://arxiv.org/pdf/2310.19923v4) or use the HTML version from the arXiv (https://r.jina.ai/https://arxiv.org/html/2310.19923v4)
How does image caption work in Reader?
keyboard_arrow_down
Reader captions all images at the specified URL and adds `Image [idx]: [caption]` as an alt tag (if they initially lack one). This enables downstream LLMs to interact with the images in reasoning, summarizing etc.
What is the scalability of the Reader? Can I use it in production?
keyboard_arrow_down
The Reader API is designed to be highly scalable. It is auto-scaled based on the real-time traffic and the maximum concurrency requests is now around 4000. We are maintaining it actively as one of the core products of Jina AI. So feel free to use it in production.
What is the rate limit of the Reader API?
keyboard_arrow_down
Please find the latest rate limit information in the table below. Note that we are actively working on improving the rate limit and performance of the Reader API, the table will be updated accordingly.

API-related common questions
code
Can I use the same API key for embedding, reranking, reader, fine-tuning APIs?
keyboard_arrow_down
Yes, the same API key is valid for all search foundation products from Jina AI. This includes the embedding, reranking, reader and fine-tuning APIs, with tokens shared between the all services.
code
Can I monitor the token usage of my API key?
keyboard_arrow_down
Yes, token usage can be monitored in the 'Buy tokens' tab by entering your API key, allowing you to view the usage history and remaining tokens.
code
What should I do if I forget my API key?
keyboard_arrow_down
If you have misplaced a topped-up key and wish to retrieve it, please contact support AT jina.ai with your registered email for assistance.
Contact
code
Do API keys expire?
keyboard_arrow_down
No, our API keys do not have an expiration date. However, if you suspect your key has been compromised and wish to retire it or transfer its tokens to a new key, please contact our support team for assistance.
Contact
code
Why is the first request for some models slow?
keyboard_arrow_down
This is because our serverless architecture offloads certain models during periods of low usage. The initial request activates or 'warms up' the model, which may take a few seconds. After this initial activation, subsequent requests process much more quickly.
code
Is user input data used for training your models?
keyboard_arrow_down
We adhere to a strict privacy policy and do not use user input data for training our models.
Billing-related common questions
attach_money
Is billing based on the number of sentences or requests?
keyboard_arrow_down
Our pricing model is based on the total number of tokens processed, allowing users the flexibility to allocate these tokens across any number of sentences, offering a cost-effective solution for diverse text analysis requirements.
attach_money
Is there a free trial available for new users?
keyboard_arrow_down
We offer a welcoming free trial to new users, which includes one million tokens for use with any of our models, facilitated by an auto-generated API key. Once the free token limit is reached, users can easily purchase additional tokens for their API keys via the 'Buy tokens' tab.
attach_money
Are tokens charged for failed requests?
keyboard_arrow_down
No, tokens are not deducted for failed requests.
attach_money
What payment methods are accepted?
keyboard_arrow_down
Payments are processed through Stripe, supporting a variety of payment methods including credit cards, Google Pay, and PayPal for your convenience.
attach_money
Is invoicing available for token purchases?
keyboard_arrow_down
Yes, an invoice will be issued to the email address associated with your Stripe account upon the purchase of tokens.
