Open a URL with a real Chromium and return its rendered state.

Use when the cheaper fetch tools (web_fetch, pdf_fetch, http_post_form) fail because the page is a SPA, JS-rendered chart, login-walled, or has a dropdown that's not a separate URL.

Args: url: The page URL. wait_for_selector: Optional CSS selector to await before reading the DOM. Use when data appears only after an AJAX call returns — e.g. ".chart svg", "table#monthly tbody tr". wait_extra_ms: Extra settle time after the wait fires (default 1500). timeout_ms: Hard navigation timeout (default 45s). screenshot: Whether to capture a PNG (default True). Adds ~200ms. full_page_screenshot: Scroll-stitch the whole page (default False). text_cap: Cap on extracted text length (default 30000).

Returns: {url, title, domain, text, screenshot_b64, screenshot_bytes, fetched_at, current_date}

Drive a real Chromium through a sequence of steps, then run Sonnet structured extraction on the final state.

Use this when the data is BEHIND an interaction — a Year/Month dropdown that fires AJAX inline, a tab to click, a "Load more" button, a form to submit. visit and extract only read the page as it loaded; act clicks/types/selects first.

Steps are a list of single-key dicts: {"click": "css-selector"} {"fill": {"selector": "#q", "value": "x"}} {"select": {"selector": "#year", "value": "2024-2025"}} {"press": {"selector": "#q", "key": "Enter"}} {"scroll": {"to": "bottom"|"top"|}} {"wait_for_selector": "css-selector"} {"wait_for_load_state": "networkidle"|"load"} {"wait_ms": 1500} {"goto": "https://…"} // mid-flow navigation {"screenshot": {"name": "after-select"}} // logged, not returned

Example — pull PPAC FY2024-25 monthly consumption (a flow that needs the year dropdown change to fire an AJAX request): act( url="https://ppac.gov.in/consumption/products-wise", steps=[ {"wait_for_selector": "#financialYear"}, {"select": {"selector": "#financialYear", "value": "2024-2025"}}, {"wait_for_load_state": "networkidle"}, {"wait_ms": 2000}, ], focus="FY2024-25 monthly LPG, MS, HSD, ATF consumption", )

Returns the same shape as extract PLUS step_results (per-step timing + ok/error) and final_url.

Args: url: Starting page URL. steps: Ordered list of action dicts (vocabulary above). focus: Extraction focus passed to Sonnet. timeout_ms: Per-step navigation / wait timeout. full_page_screenshot: Whether the final screenshot is full-page.

Returns: {url, domain, title, dateline, summary, key_facts[], numeric_values[], dates[], tables_summary[], step_results[], final_url, kind: "browser"}.

Visit a URL → focused Sonnet structured extraction.

Sends BOTH rendered text AND a screenshot to Sonnet — so numbers drawn via canvas / SVG (chart values on PPAC, RBI, NSE dashboards) that don't appear in the DOM still get extracted. Same returned shape as pdf_fetch_structured / web_fetch_structured on authority-web-search-mcp.

Args: url: The page URL. focus: What to extract, e.g. "monthly LPG, MS, HSD consumption for FY2024-25" or "Q4 FY26 EBITDA margin and revenue". wait_for_selector: Optional CSS selector to await (see visit). full_page_screenshot: Default True so charts below the fold are seen.

Returns: {url, domain, title, dateline, summary, key_facts[], numeric_values[], dates[], tables_summary[], kind: "browser"}.
