Block: Jina Block — Zelaxy Docs

The Jina block transforms web content into clean, readable text using Jina AI's advanced extraction capabilities. Reach for it when you need to pull meaningful content from a webpage while preserving important information and optionally gathering its links.

Overview

Property	Value
Type	`jina`
Category	tools
Color	`#333333`

When to Use

Extract the main readable text from an article or webpage for downstream LLM processing
Strip away navigation, ads, and boilerplate to get clean content
Collect all the links found on a page for crawling or research workflows
Get a structured JSON response when you need machine-parseable output
Use Reader LM v2 for higher-quality content extraction on complex pages
Feed scraped page content into an agent block for summarization or analysis

Configuration

URL

The webpage address to extract content from. Required. Supports any valid http:// or https:// URL; the block normalizes the scheme before forwarding to Jina.

Options

A checkbox list controlling extraction behavior. All options are optional and default to off.

Option	id	Effect
Use Reader LM v2	`useReaderLMv2`	Sends `X-Respond-With: readerlm-v2` to use the improved reader model for better extraction quality on complex pages
Gather Links	`gatherLinks`	Sends `X-With-Links-Summary: true` to append a summary of all links found on the page to the output
JSON Response	`jsonResponse`	Sets `Accept: application/json` so the Jina API returns a structured JSON payload instead of plain text

API Key

Your Jina AI API key, stored securely (password field). Required. Passed as Authorization: Bearer <key>. Use {{JINA_API_KEY}} to pull from an environment variable.

Inputs & Outputs

- url (string) — URL to extract content from
- useReaderLMv2 (boolean) — Use Reader LM v2 for better quality extraction
- gatherLinks (boolean) — Gather all links found on the page
- jsonResponse (boolean) — Return response in JSON format instead of plain text
- apiKey (string) — Jina AI API key for authentication

Tools

Jina Reader (jina_read_url) — Extracts and processes web content into clean, LLM-friendly text using the Jina AI Reader API (https://r.jina.ai/). Supports advanced content parsing, optional link gathering, and plain-text or JSON output formats. Takes url, apiKey, and the three optional boolean flags as parameters; returns content.
