Capture a page, inspect its DOM, and optionally automate it

Browser capture availability depends on your account capabilities and platform restrictions. Check GET /credits before starting browser work. A platform refusal returns HTTP 403 without upgrade_url: BROWSER_ISOLATION_REQUIRED when browser execution is unavailable, or BROWSER_EXECUTION_DENIED with reason public_capture_not_enabled when public capture is unavailable for your account. Upgrading or immediately retrying does not clear these refusals. Returns a direct result when it fits within the synchronous response budget; explicit async requests and rich results that exceed it return 202 with a durable job ID instead. Set responseType to json whenever semantic analysis, diagnostics, extraction, cleanup reporting, or action results are needed. A binary response is raw image/PDF bytes; binary delivery does not depend on the ordering of values in Accept.
