Agentic Browser

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

Quick Start

Requires inference.sh CLI (infsh). Install instructions

infsh login

# Open a page and get interactive elements
infsh app run agent-browser --function open --input '{"url": "https://example.com"}' --session new

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)

# 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 '{}'

Functions

Function	Description
open	Navigate to URL, configure browser (viewport, proxy, video recording)
snapshot	Re-fetch page state with @e refs after DOM changes
interact	Perform actions using @e refs (click, fill, drag, upload, etc.)
screenshot	Take page screenshot (viewport or full page)
execute	Run JavaScript code on the page
close	Close session, returns video if recording was enabled

Interact Actions

Action	Description	Required Fields
click	Click element	ref
dblclick	Double-click element	ref
fill	Clear and type text	ref, text
type	Type text (no clear)	text
press	Press key (Enter, Tab, etc.)	text
select	Select dropdown option	ref, text
hover	Hover over element	ref
check	Check checkbox	ref
uncheck	Uncheck checkbox	ref
drag	Drag and drop	ref, target_ref
upload	Upload file(s)	ref, file_paths
scroll	Scroll page	direction (up/down/left/right), scroll_amount
back	Go back in history	-
wait	Wait milliseconds	wait_ms
goto	Navigate to URL	url

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:

# 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):

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:

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:

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:

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

JavaScript Execution

Run custom JavaScript:

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