Stealth Browser Agent — AI Browser Automation
Pricing
from $17.00 / 1,000 step completeds
Stealth web automation agent and AI browser agent for sites with bot detection: computer use and browser use on the web. Send a URL and a plain-language task; it navigates, fills and submits forms, runs multi-step flows, and returns structured JSON. Anti-detection fingerprinting, residential proxy.
Final URL
url
Required
The URL of the page after all navigation and interactions completed. May differ from the starting URL if the agent followed links or was redirected.
Task
task
Required
Echo of the input task description, for traceability.
Status
status
Required
Outcome of the task. One of: completed (task finished successfully), failed (agent could not accomplish the task), timeout (hard deadline reached), max_steps_reached (step limit hit before completion), budget_exhausted (maxTotalChargeUsd reached before completion). Capped runs (max_steps_reached / budget_exhausted) may still carry a best-effort partial in result — check resultComplete.
Result
result
Required
Structured data extracted by the agent. Shape matches outputSchema if one was provided, otherwise best-effort JSON — usually an object, or a top-level array when the task asks for a bare list. Contains the information the task asked for. On a capped run this may be a best-effort PARTIAL synthesized from the data collected before the cap — fields without collected data are null, and resultComplete is false. Always check resultComplete before treating this as a full answer.
Result Complete
resultComplete
Optional
True only when status is completed. False means result is either empty or a best-effort partial from a capped run — machine-checkable so agent consumers can decide to use the partial or re-run with a higher maxSteps / maxTotalChargeUsd.
Action Log
steps
Required
Ordered list of actions the agent took. Each entry records the action type, target, reasoning, and whether it succeeded. Useful for debugging and understanding agent behavior.
[ { "step": 1, "tool": "get_text", "args": { "selector": "h1" }, "result_summary": "Example Domain", "success": true }]Screenshot URL
screenshotUrl
Optional
Public URL of a full-page screenshot of the final page state, stored in the run's key-value store. Populated on every successful run.
Step Transcript URL
stepTranscriptUrl
Optional
Public URL of the capped full step transcript, stored in the run's key-value store. Populated on incomplete runs after at least one step.
Error
error
Optional
Human-readable error message when status is not 'completed'. Absent on successful runs.
Error class
errorClass
Optional
Machine-routable failure class. source_error is a temporary target-site failure and is retryable; source_walled is an access challenge and may be retryable; no_content, malformed_input, and agent_error are not retryable without changing the page, input, or task; not_covered means this Actor does not operate on that target, so re-running the same input will not change the answer; budget_exhausted is retryable with a larger budget. Null on success.
Retry advice
retry
Optional
Machine-readable retry guidance for this record, derived from errorClass. Null when the record is a result. 'never' = the source answered, or we do not cover this target: re-running the same input returns the same answer, do not re-run. 'with_changes' = the input for this record must change (see error for what): do not re-run unchanged. 'later' = a transient fault on the source or our side, or the run's budget/deadline ran out before this record: re-run the same input after a short delay.
