What is x-browser?
x-browser is a high-performance automation skill designed to interact with X (Twitter) through the HTTP Browser API. Unlike traditional methods that rely on the increasingly expensive and restrictive official API, this tool mimics human browser behavior to perform actions. It is a core component of the Openclaw Skills ecosystem for developers who need to programmatically manage social media presence.
By leveraging sequence-based actions such as clicking, typing, and waiting for specific DOM selectors, x-browser provides a resilient way to handle posts, replies, and complex threads. The skill operates via a headless browser environment, ensuring that your automation remains functional even as official API specifications change, while significantly reducing operational costs for social media bots and agents.
x-browser Use Cases
- Automating daily news summaries or status updates directly to X.
- Creating multi-post educational threads without manual data entry.
- Bypassing the high costs of X Basic and Pro API tiers for small to medium projects.
- Programmatically uploading AI-generated media using Openclaw Skills integration.
- Managing multiple account interactions through secure browser-based sequences.
How x-browser Works
- The skill receives a POST request containing a URL and a sequence of browser actions.
- It initializes a session with the HTTP Browser API using your unique worker URL and secret.
- The browser navigates to the specified X.com endpoint, such as the tweet compose page.
- It executes the action array step-by-step, targeting specific data-testid selectors to input text and attach media.
- Upon completion of the sequence, it triggers the post button and captures a screenshot for verification and logging.
x-browser Setup
To start using this skill, configure your environment variables and use the sequence API.
export MOLTBOT_URL="https://your-worker.workers.dev"
export CDP_SECRET="your-secret"
You can then trigger a tweet via a simple curl command:
curl -X POST "${MOLTBOT_URL}/browser/sequence?secret=${CDP_SECRET}" \
-H "Content-Type: application/json" \
-d '{
"url": "https://x.com/compose/tweet",
"actions": [
{"type": "waitForSelector", "selector": "[data-testid=\"tweetTextarea_0\"]"},
{"type": "type", "selector": "[data-testid=\"tweetTextarea_0\"]", "text": "Hello from Openclaw Skills!"},
{"type": "wait", "ms": 1000},
{"type": "click", "selector": "[data-testid=\"tweetButton\"]"},
{"type": "wait", "ms": 3000},
{"type": "screenshot"}
]
}'
x-browser Data Schema & Taxonomy
The skill organizes its operations using a JSON-based action manifest. Below is the primary metadata and action structure used within Openclaw Skills:
| Field | Type | Description |
|---|---|---|
url |
string | The target X.com page (e.g., /home, /compose/tweet) |
type |
string | The action type: waitForSelector, type, click, wait, or screenshot |
selector |
string | The CSS selector or data-testid used to find UI elements |
text |
string | The content to be typed into text areas or input fields |
ms |
number | Duration in milliseconds for wait actions |
x-browser Advanced Features
- Multi-tweet thread support using the dynamic addButton selector logic.
- Media upload integration allowing up to 4 images per post sequence.
- Human-like interaction modeling with configurable wait times to minimize account risk.
- Automated login flow sequences including credential injection and session verification.
