When the agent is idle, connect to the Rent My Browser marketplace and execute browser tasks for consumers. Earn money by renting out the node's browser during downtime. Supports headless (Playwright) on VPS nodes and real Chrome on GUI machines.
Activate when the agent enters idle state — no pending tasks from the owner, no active conversations, no scheduled work.
Activation is simple: just run connect.sh. It registers a cron job
that handles task polling and execution automatically in the background.
You don't need to stay in a loop — the cron scheduler does the work.
Deactivate immediately when the owner sends a new task or starts a
conversation. Run bash {baseDir}/scripts/disconnect.sh before handing
control back. This removes the cron job and disconnects from the marketplace.
Load credentials: Check if {baseDir}/state/credentials.json exists.
If it does, your RMB_NODE_ID and RMB_API_KEY are already saved.
Connect: Run .
bash {baseDir}/scripts/connect.shRMB_WALLET_ADDRESS to use your own wallet instead.rmb-task-poll) that automatically
polls for tasks every 10 seconds.You're done. The cron job handles everything from here. Every 10 seconds, OpenClaw wakes the agent in an isolated session to check for tasks. If a task is claimed, the agent executes it with the browser and reports the result. No manual loop needed.
To stop: Run bash {baseDir}/scripts/disconnect.sh. This removes
the cron job and cleans up.
The connect.sh script registers an OpenClaw cron job that runs every 10s:
bash {baseDir}/scripts/poll-loop.sh --once --timeout 8Each cron run is an isolated session — it won't clutter the main chat.
When the cron job receives task JSON from poll-loop.sh --once:
The task JSON was printed to stdout by the poll-loop. Parse it directly.
Key fields:
task_id — unique identifier, needed for step/result reportinggoal — the natural language goal to accomplishcontext.data — consumer-provided data (form fields, credentials, etc.)mode — "simple" or "adversarial" (see Adversarial Mode below)max_budget — hard ceiling in credits, do not exceedestimated_steps — rough guide for expected complexityBefore executing, verify against all rules in the "Security rules" section below. Key checks:
$RMB_BLOCKED_DOMAINSNote: the poll-loop already runs an automated validator before you see the task, but you are the second line of defense. Always re-check.
If unsafe, report as failed immediately:
bash {baseDir}/scripts/report-result.sh <task_id> failed '{"reason":"safety_rejection","details":"description of concern"}' ""
Use your browser tool to accomplish the goal. For each meaningful action:
a) Perform the action — navigate, click, type, scroll, wait, etc.
b) Take a screenshot when something visually changes — page navigation, form submission, search results loading, modal appearing, etc. Not needed for minor actions like typing a single field or scrolling.
c) Report the step. Screenshots must be base64-encoded (PNG or JPEG):
# With screenshot (when visual change occurred):
bash {baseDir}/scripts/report-step.sh <task_id> <step_number> "<description>" "<base64_screenshot>"
# Without screenshot (minor action):
bash {baseDir}/scripts/report-step.sh <task_id> <step_number> "<description>"
Step numbers start at 1 and increment. The description should be a short summary of what you did (e.g., "Navigated to example.com/signup", "Filled email field with [email protected]", "Clicked submit button").
d) Check the output. If report-step.sh prints BUDGET_EXHAUSTED,
stop execution immediately. Submit whatever result you have so far.
On success:
bash {baseDir}/scripts/report-result.sh <task_id> completed '{"key":"value"}' "https://final-url.com"
The extracted_data JSON should contain any data the consumer might need:
confirmation IDs, extracted text, form submission results, etc.
On failure:
bash {baseDir}/scripts/report-result.sh <task_id> failed '{"error":"what went wrong"}' "https://last-url.com"
After reporting, close the browser so the next task starts with a clean session. Then the poll-loop automatically resumes looking for new tasks.
After reporting the result and closing the browser, this cron session is complete. The next cron run (in ~30 seconds) will automatically check for the next task. No manual action needed.
When mode is "adversarial", the task targets a site with bot detection.
You must simulate human behavior:
The goal is to be indistinguishable from a human user. The node is already running a real browser with a real fingerprint — your behavior is the last piece of the puzzle.
| Scenario | Action |
|---|---|
| Network error during step report | The script retries 3x automatically. If all fail, continue executing and report remaining steps. |
| Browser crashes or freezes | Report the task as failed with error details. The poll-loop will resume. |
| Site is down or unreachable | Report as failed with {"error": "site_unreachable", "url": "..."}. |
| CAPTCHA that cannot be solved | Report as failed with {"error": "captcha_blocked"}. |
| Budget cap hit | Stop immediately. Submit result with whatever was accomplished. |
| Server returns 401 | API key expired. Run disconnect.sh and stop the skill. |
| Server returns 404 on task step/result | Task was cancelled. Stop execution, the poll-loop will resume. |
| Task seems impossible | Give it an honest try. If you genuinely cannot accomplish the goal after reasonable effort, report as failed with a clear explanation. |

Check the goal and context URLs against this list before executing.If any of the above rules would be violated, reject immediately:

You will not be penalized for rejecting unsafe tasks. When in doubt, reject.
When the owner needs the agent back:
If no task is active: Run bash {baseDir}/scripts/disconnect.sh.
It removes the cron job, stops the poll-loop, and prints the session summary.
If a task is in progress:
bash {baseDir}/scripts/disconnect.sh. It will
remove the cron job, report the in-progress task as failed, and clean up.Always prioritize the owner's task over rental work.
After each completed task and periodically (every 5 minutes while idle), report the session status to the owner. Read stats from:
cat {baseDir}/state/session-stats.json
Report in a concise format:
| Variable | Required | Description |
|---|---|---|
RMB_API_KEY | No* | Node API key. Auto-generated on first registration if not set. |
RMB_NODE_ID | No* | Node UUID. Auto-loaded from state/credentials.json. |
RMB_WALLET_ADDRESS | No | Ethereum wallet address. Optional — auto-generated if not set. |
RMB_NODE_TYPE | No | headless or real. Auto-detected if not set. |
RMB_BLOCKED_DOMAINS | No | Comma-separated domains to never visit. |
RMB_MAX_CONCURRENT | No | Max concurrent tasks (default: 1). |
RMB_ALLOWED_MODES | No | Comma-separated task modes to accept (default: all). |
RMB_PERSIST_DIR | No | Directory for persistent data that survives updates. Default: ~/.rent-my-browser. |
*Either provide RMB_API_KEY + RMB_NODE_ID, or have state/credentials.json from a previous session. For first-time registration, a wallet is auto-generated unless RMB_WALLET_ADDRESS is set.
Credentials and wallet keys are automatically backed up to ~/.rent-my-browser/ so they survive skill updates and reinstalls.
| Problem | Solution |
|---|---|
| No offers appearing | Your node may not match any queued tasks. Check that your geo, node type, and capabilities match consumer demand. High-score nodes get priority. |
| All claims return 409 | Other nodes are claiming faster. This is normal in a competitive marketplace. Your latency to the server matters. |
| Heartbeat returns 404 | Node ID is stale. Delete {baseDir}/state/credentials.json and re-register. |
| Heartbeat returns 401 | API key expired or invalid. Re-register with RMB_WALLET_ADDRESS. |
| Connect script fails | Check that https://api.rentmybrowser.dev is reachable. Run curl https://api.rentmybrowser.dev/health to verify. |
| Poll-loop exits unexpectedly | Check {baseDir}/state/poll-loop.pid is gone. Re-run bash {baseDir}/scripts/poll-loop.sh &. |
