简介

jina 是一个轻量级的命令行工具，封装了 Jina AI Reader API，可以将任意 URL 转换为 LLM 友好的输入格式。特别适合阅读 X (Twitter)、博客、新闻网站等复杂网页。

核心功能：

• read - 读取 URL 内容，输出 Markdown/Text/HTML 格式
• search - 网络搜索，自动获取并处理搜索结果

安装指南

jina 有三种独立的安装方式，根据你的使用场景选择：

方式一：OpenClaw Skill（推荐本地 AI 助理）

什么是 OpenClaw？

OpenClaw 是一个本地 AI 助理（可以理解为"有终端权限的 Claude"），运行在你的机器上。它通过 Skills 插件扩展能力，支持 9000+ 个技能插件。

适用场景：本地 AI 助理、自动化工作流、文件系统操作

安装方式 - 直接复制 skill 文件：

# 创建 jina-cli skill 目录并下载
mkdir -p ~/.openclaw/workspace/skills/jina-cli
curl -o ~/.openclaw/workspace/skills/jina-cli/SKILL.md \
  https://raw.githubusercontent.com/geekjourneyx/jina-cli/main/skills/jina-cli/SKILL.md

验证安装：

# 启动 OpenClaw
openclaw

# 在 OpenClaw 中直接使用 jina 命令
# skill 会自动从 ~/.openclaw/workspace/skills/jina-cli/ 加载

你将获得：

• ✅ 本地 AI 助理直接调用 jina read 和 jina search
• ✅ 无需安装 CLI 二进制
• ✅ 可以处理本地文件、执行脚本等

方式二：Claude Code Skill（推荐用于 AI 辅助开发）

适用场景：在 Claude Code 中使用 AI 协助你处理网页内容

安装步骤：

# 1. 确保已安装 Node.js 和 Claude Code
node --version
# v18.0.0 或更高版本

# 2. 安装 jina skill
npx skills add https://github.com/geekjourneyx/jina-cli --skill jina-cli

安装后验证：

# 在 Claude Code 中可以直接使用
# 无需额外操作，skill 会自动加载

你将获得：

• ✅ 在 Claude Code 中直接调用 jina read 和 jina search 命令
• ✅ AI 会自动理解 jina 的功能和使用方式
• ✅ 无需手动安装 CLI 二进制文件

方式三：CLI 二进制文件（推荐用于终端使用）

适用场景：在终端/脚本中使用，或与其他工具集成

一键安装（Linux/macOS）

curl -fsSL https://raw.githubusercontent.com/geekjourneyx/jina-cli/main/scripts/install.sh | bash

安装脚本会自动：

1. 检测你的系统架构（Linux/macOS，amd64/arm64）
2. 下载对应平台的二进制文件
3. 安装到 ~/.local/bin/jina 或 ~/bin/jina
4. 提示如何添加到 PATH（如需要）

验证安装

# 检查是否安装成功
jina --version
# 预期输出: jina version 1.0.0 (构建时间: ..., 提交: ...)

# 测试基本功能
jina read --url "https://example.com"

手动安装

如果自动安装失败，可以手动下载：

# 1. 下载对应平台的二进制
# Linux amd64:
wget https://github.com/geekjourneyx/jina-cli/releases/latest/download/jina-linux-amd64 -O jina
chmod +x jina
sudo mv jina /usr/local/bin/

# macOS ARM64 (Apple Silicon):
wget https://github.com/geekjourneyx/jina-cli/releases/latest/download/jina-darwin-arm64 -O jina
chmod +x jina
sudo mv jina /usr/local/bin/

# 2. 验证安装
jina --version

从源码构建

git clone https://github.com/geekjourneyx/jina-cli.git
cd jina-cli
go build -o jina ./cli
sudo mv jina /usr/local/bin/

三种安装方式对比

推荐选择：

• OpenClaw → 最强能力，本地运行，可操作文件系统
• Claude Code → 开发体验好，AI 辅助编码
• CLI 二进制 → 最轻量，适合脚本集成

注意：三种方式完全独立，可以同时安装，互不干扰。

快速开始

读取网页内容

# 读取单个 URL
jina read --url "https://example.com"

# 读取 X (Twitter) 帖子
jina read -u "https://x.com/user/status/123456789" --with-alt

# 输出 Markdown 格式
jina read -u "https://example.com" --output markdown

# 保存到文件
jina read -u "https://example.com" --output-file result.md

批量处理

# 从文件读取 URL 列表
cat > urls.txt << EOF
https://example.com/page1
https://example.com/page2
https://x.com/user/status/123
EOF

jina read --file urls.txt

网络搜索

# 搜索关键词
jina search --query "golang latest news"

# 限定搜索站点
jina search -q "AI developments" --site techcrunch.com --site theverge.com

# 限制结果数量
jina search -q "climate change" --limit 10

配置管理

配置文件位于 ~/.jina-reader/config.yaml：

# 查看所有配置
jina config list

# 设置配置项
jina config set timeout 60
jina config set with-generated-alt true

# 获取单个配置
jina config get timeout

# 查看配置文件路径
jina config path

配置项说明

优先级： 命令行参数 > 环境变量 > 配置文件 > 默认值

API Key 使用

添加 API Key 可以获得更高的速率限制：

# 方式 1：配置文件设置
jina config set api_key jina_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# 方式 2：环境变量
export JINA_API_KEY=jina_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# 方式 3：命令行参数
jina read -u "https://example.com" -k jina_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

获取 API Key：访问 Jina AI Reader 注册并获取。

输出格式

JSON 格式（默认）

{
  "success": true,
  "data": {
    "url": "https://example.com",
    "title": "Example Domain",
    "content": "# Example Domain\n\nThis domain is..."
  }
}

Markdown 格式

jina read -u "https://example.com" --output markdown

输出：

# Example Domain

**Source**: https://example.com

---

# Example Domain

This domain is for use in illustrative examples...

高级用法

禁用缓存

jina read -u "https://example.com" --no-cache

使用代理

jina read -u "https://example.com" --proxy "http://proxy.com:8080"

CSS 选择器提取

# 只提取指定元素
jina read -u "https://example.com" --target-selector "article.main"

# 等待元素加载
jina read -u "https://example.com" --wait-for-selector "#content"

处理 SPA 应用

# 对于带 hash 路由的 SPA，使用 POST 方法
jina read -u "https://example.com/#/route" --post

设置 Cookie

jina read -u "https://example.com" --cookie "session=abc123"

与 AI Agent 集成

# 在 Claude Code 或其他 AI 工具中使用
jina read -u "https://x.com/elonmusk/status/123456" --output json

# 搜索最新信息
jina search -q "golang 1.24 release notes" --output json

Overview

jina is a lightweight CLI tool that wraps the Jina AI Reader API to convert any URL into LLM-friendly input. Perfect for reading X (Twitter), blogs, news sites, and other complex web pages.

Features:

• read - Extract content from URLs in Markdown/Text/HTML format
• search - Search the web with AI-powered result processing

Installation Guide

jina offers two independent installation methods. Choose based on your use case:

Method 1: Claude Code Skill (Recommended for AI-Assisted Development)

Use case: Using jina within Claude Code with AI assistance

Installation steps:

# 1. Ensure Node.js and Claude Code are installed
node --version
# v18.0.0 or higher

# 2. Install jina skill
npx skills add https://github.com/geekjourneyx/jina-cli --skill jina-cli

Verify installation:

# You can now use jina commands directly in Claude Code
# No additional steps needed, skill loads automatically

You get:

• ✅ Direct access to jina read and jina search commands in Claude Code
• ✅ AI automatically understands jina's functionality
• ✅ No manual CLI binary installation required

Method 2: CLI Binary (Recommended for Terminal/Scripting)

Use case: Using in terminal/scripts, or integrating with other tools

One-line Installation (Linux/macOS)

curl -fsSL https://raw.githubusercontent.com/geekjourneyx/jina-cli/main/scripts/install.sh | bash

The installation script automatically:

1. Detects your system architecture (Linux/macOS, amd64/arm64)
2. Downloads the appropriate binary for your platform
3. Installs to ~/.local/bin/jina or ~/bin/jina
4. Prompts to add to PATH if needed

Verify Installation

# Check if installation succeeded
jina --version
# Expected output: jina version 1.0.0 (build: ..., commit: ...)

# Test basic functionality
jina read --url "https://example.com"

Manual Installation

If auto-install fails, download manually:

# 1. Download binary for your platform
# Linux amd64:
wget https://github.com/geekjourneyx/jina-cli/releases/latest/download/jina-linux-amd64 -O jina
chmod +x jina
sudo mv jina /usr/local/bin/

# macOS ARM64 (Apple Silicon):
wget https://github.com/geekjourneyx/jina-cli/releases/latest/download/jina-darwin-arm64 -O jina
chmod +x jina
sudo mv jina /usr/local/bin/

# 2. Verify installation
jina --version

Build from Source

git clone https://github.com/geekjourneyx/jina-cli.git
cd jina-cli
go build -o jina ./cli
sudo mv jina /usr/local/bin/

Comparison

Recommendations:

• OpenClaw → Most capable, runs locally, full system access
• Claude Code → Best dev experience, AI-assisted coding
• CLI Binary → Lightweight, perfect for scripts

Note: The three methods are completely independent. Install any or all without conflicts.

Quick Start

Read Web Content

# Read a single URL
jina read --url "https://example.com"

# Read X (Twitter) post
jina read -u "https://x.com/user/status/123456789" --with-alt

# Output as Markdown
jina read -u "https://example.com" --output markdown

# Save to file
jina read -u "https://example.com" --output-file result.md

Batch Processing

# Read from URL list file
cat > urls.txt << EOF
https://example.com/page1
https://example.com/page2
https://x.com/user/status/123
EOF

jina read --file urls.txt

Web Search

# Search for a query
jina search --query "golang latest news"

# Restrict to specific sites
jina search -q "AI developments" --site techcrunch.com --site theverge.com

# Limit results
jina search -q "climate change" --limit 10

Configuration

Config file location: ~/.jina-reader/config.yaml

# List all configuration
jina config list

# Set configuration
jina config set timeout 60
jina config set with-generated-alt true

# Get single configuration
jina config get timeout

# Show config file path
jina config path

Configuration Options

Priority: CLI args > Env vars > Config file > Defaults

API Key Usage

Adding an API key provides higher rate limits:

# Method 1: Set via config file
jina config set api_key jina_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# Method 2: Set via environment variable
export JINA_API_KEY=jina_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# Method 3: Pass via command line
jina read -u "https://example.com" -k jina_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
