Agentic Browser

Browser automation for AI agents via inference.sh. Uses Playwright under the hood with a simple 
@e
ref system for element interaction.
Agentic Browser

Quick Start

bash
# Install CLI
curl -fsSL https://cli.inference.sh | sh && infsh login

# Open a page and get interactive elements
infsh app run agent-browser --function open --input '{"url": "https://example.com"}' --session new
Install note: The install script only detects your OS/architecture, downloads the matching binary from 
dist.inference.sh
, and verifies its SHA-256 checksum. No elevated permissions or background processes. Manual install & verification available.

Core Workflow

Every browser automation follows this pattern:
  1. Open - Navigate to URL, get 
    @e
    refs for elements
  2. Interact - Use refs to click, fill, drag, etc.
  3. Re-snapshot - After navigation/changes, get fresh refs
  4. Close - End session (returns video if recording)
bash
# 1. Start session
RESULT=$(infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com/login"
}')
SESSION_ID=$(echo $RESULT | jq -r '.session_id')
# Elements: @e1 [input] "Email", @e2 [input] "Password", @e3 [button] "Sign In"

# 2. Fill and submit
infsh app run agent-browser --function interact --session $SESSION_ID --input '{
  "action": "fill", "ref": "@e1", "text": "user@example.com"
}'
infsh app run agent-browser --function interact --session $SESSION_ID --input '{
  "action": "fill", "ref": "@e2", "text": "password123"
}'
infsh app run agent-browser --function interact --session $SESSION_ID --input '{
  "action": "click", "ref": "@e3"
}'

# 3. Re-snapshot after navigation
infsh app run agent-browser --function snapshot --session $SESSION_ID --input '{}'

# 4. Close when done
infsh app run agent-browser --function close --session $SESSION_ID --input '{}'

Element Refs

Elements are returned with 
@e
refs:
@e1 [a] "Home" href="/"
@e2 [input type="text"] placeholder="Search"
@e3 [button] "Submit"
@e4 [select] "Choose option"
@e5 [input type="checkbox"] name="agree"
Important: Refs are invalidated after navigation. Always re-snapshot after:
  • Clicking links/buttons that navigate
  • Form submissions
  • Dynamic content loading

Features

Video Recording

Record browser sessions for debugging or documentation:
bash
# Start with recording enabled (optionally show cursor indicator)
SESSION=$(infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com",
  "record_video": true,
  "show_cursor": true
}' | jq -r '.session_id')

# ... perform actions ...

# Close to get the video file
infsh app run agent-browser --function close --session $SESSION --input '{}'
# Returns: {"success": true, "video": <File>}

Cursor Indicator

Show a visible cursor in screenshots and video (useful for demos):
bash
infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com",
  "show_cursor": true,
  "record_video": true
}'
The cursor appears as a red dot that follows mouse movements and shows click feedback.

Proxy Support

Route traffic through a proxy server:
bash
infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com",
  "proxy_url": "http://proxy.example.com:8080",
  "proxy_username": "user",
  "proxy_password": "pass"
}'

File Upload

Upload files to file inputs:
bash
infsh app run agent-browser --function interact --session $SESSION --input '{
  "action": "upload",
  "ref": "@e5",
  "file_paths": ["/path/to/file.pdf"]
}'

Drag and Drop

Drag elements to targets:
bash
infsh app run agent-browser --function interact --session $SESSION --input '{
  "action": "drag",
  "ref": "@e1",
  "target_ref": "@e2"
}'

JavaScript Execution

Run custom JavaScript:
bash
infsh app run agent-browser --function execute --session $SESSION --input '{
  "code": "document.querySelectorAll(\"h2\").length"
}'
# Returns: {"result": "5", "screenshot": <File>}

Examples

Form Submission

bash
SESSION=$(infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com/contact"
}' | jq -r '.session_id')

Sessions

Browser state persists within a session. Always:
  1. Start with 
    --session new
    on first call
  2. Use returned 
    session_id
    for subsequent calls
  3. Close session when done
