Configuration

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

Priority: Command args > Environment vars > Config file > Defaults

Environment variables:

• JINA_API_BASE_URL - Read API URL (default: https://r.jina.ai/)
• JINA_SEARCH_API_URL - Search API URL (default: https://s.jina.ai/)
• JINA_TIMEOUT - Request timeout in seconds (default: 30)
• JINA_WITH_GENERATED_ALT - Enable image captioning (default: false)
• JINA_OUTPUT_FORMAT - Output format: json/markdown (default: json)
• JINA_PROXY_URL - Proxy server URL

Config commands:

# Set API Key (Required for --with-alt)
jina config set key your_jina_api_key

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

# View configuration
jina config list
jina config get timeout
jina config path

Troubleshooting

401 Authentication Required

If you receive a 401 Unauthorized error when using --with-alt, ensure you have a valid API key configured: jina config set key YOUR_API_KEY

Command not found (Windows)

If jina is not recognized after go install, ensure $HOME\go\bin is in your system PATH and the binary is named jina.exe (defaults to cli.exe).

Output formats

JSON format (default, machine-readable):

{
  "success": true,
  "data": {
    "url": "https://example.com",
    "content": "# Extracted Content\n\n...",
    "title": "Page Title"
  }
}

Markdown format (human-readable):

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

Common use cases

Reading social media posts

# X (Twitter) posts
jina read -u "https://x.com/elonmusk/status/123456" --with-alt

# The --with-alt flag enables VLM image captioning for embedded images

Reading articles/blogs

# Standard article
jina read -u "https://blog.example.com/article"

# With specific format
jina read -u "https://example.com" --format text --output markdown

Research workflows

# 1. Search for topic
jina search -q "quantum computing 2025" --limit 10

# 2. Read specific results
jina read --file search_results.txt

Batch processing

Create a file with one URL per line:

cat > urls.txt << EOF
https://example.com/page1
https://example.com/page2
https://x.com/user/status/123
EOF

jina read --file urls.txt --output markdown
