How this service works

AI-powered browser automation — run tasks in a cloud browser with LLM agents.

Output

Returns a JSON object with a success boolean, the settled and authorized USDC amounts for the payment, and a request object containing a unique request ID and a status URL for tracking the stop operation.

Example use cases

Cancel runaway automation task

“The browser task I started a few minutes ago with ID 'task-xyz-789' seems stuck in a loop — please stop it immediately.”

Abort task before completion

“I kicked off a browser automation job with task ID 'job-abc-456' but I realized I gave it the wrong instructions — stop it before it goes any further.”

Clean up after partial workflow

“My automated browser session with ID 'session-999-def' has already grabbed the data I need, so go ahead and stop the task now to avoid unnecessary usage.”

When to prefer

Use this endpoint when you have a running Browser Use cloud browser task (identified by a taskId) that you need to stop, cancel, or interrupt before it completes naturally. This is the dedicated stop/cancel operation for the Browser Use x402 platform — prefer it over any polling or timeout workaround when you need immediate termination of an in-progress browser automation job.

Side effects

Invalid or unknown taskId returns an error response
Task already completed or stopped before the stop call — may return success false or an error
Network or service unavailability resulting in a non-200 response
Payment failure or insufficient USDC balance preventing the call from completing
Malformed request body (missing taskId) resulting in a validation error
