Launch a persistent browser session for multi-step workflows.
Call once at the start of a task and reuse the returned session_id for
all subsequent calls; use wavexis_navigate with session_id omitted for
one-off page fetches instead.
Side effects: Launches a browser process (or connects to an existing
one) and allocates server-side session state; may open network
connections to remote/cloud browsers.
Returns: JSON string with keys: 'status' ('ok'/'error'),
'session_id' (str), 'backend' (str).
Close a browser session and release all associated resources.
Call when the session is no longer needed to free memory and browser
processes; use wavexis_close_tab to close individual tabs instead.
Side effects: Terminates the browser process (or disconnects from a
remote one) and frees session state. Destructive — all unsaved page
state is lost.
Returns: JSON string with keys: 'status' ('ok'/'error'),
'session_id' (str).
Query metadata and current URL of an active browser session.
Use to inspect session health or retrieve the current page URL; use
wavexis_list_tabs for tab-level details instead.
Side effects: None — read-only; queries in-memory session state and
the browser's current URL.
Returns: JSON string with keys: 'status' ('ok'/'error'),
'session_id' (str), 'backend' (str), 'created_at' (str),
'current_url' (str).
Navigate the browser to a URL with a configurable wait strategy.
Use for direct URL navigation; use wavexis_back/wavexis_forward for
history navigation, or wavexis_act for natural-language interaction
instead.
Side effects: Issues a network request to the target URL and replaces
the current page content; may auto-create a stateless session if
session_id is omitted.
Returns: JSON string with keys: 'status' ('ok'/'error'), 'url' (str).
Navigate backward one step in the browser history.
Use for history navigation instead of wavexis_navigate when the target
is the previous page.
Side effects: Changes the active page to the previous history entry;
may trigger network requests if that page was not cached.
Returns: JSON string with keys: 'status' ('ok'/'error').
Navigate forward one step in the browser history.
Use after wavexis_back to restore a page; use wavexis_navigate for
direct URL navigation instead.
Side effects: Changes the active page to the next history entry; may
trigger network requests if that page was not cached.
Returns: JSON string with keys: 'status' ('ok'/'error').
Reload the current page, optionally bypassing the cache.
Use to refresh stale content or retry a failed load; use
wavexis_navigate to go to a different URL instead.
Side effects: Re-issues network requests for the current page and its
resources; discards in-memory page state.
Returns: JSON string with keys: 'status' ('ok'/'error').
Stop all pending navigations and resource loads in the session.
Use when a page load is hanging or no longer needed; use wavexis_wait
to wait for a load to complete instead.
Side effects: Aborts in-flight network requests and pending
navigations; the page is left in its current partial state.
Returns: JSON string with keys: 'status' ('ok'/'error').
Block until a page condition (load, selector, URL, network idle) is met.
Use after wavexis_navigate when the wait strategy was 'none', or to
wait for dynamic content; use wavexis_stop to cancel a load instead.
Side effects: None — read-only polling with no page mutations; blocks
the tool call up to the configured timeout.
Returns: JSON string with keys: 'status' ('ok'/'error'),
'elapsed_ms' (int).
Capture a screenshot of a web page or matched element.
Use ``wavexis_pdf`` when a print-ready document is needed, or
``wavexis_annotated_screenshot`` when labelled element markers are
required.
Side effects: launches/acquires a browser backend, navigates to ``url``
if provided, optionally evaluates ``js``; writes to ``output_path`` when
given.
Returns: JSON string with keys: 'status' ('ok'/'error'), 'format'
(str), 'base64' (str) or 'path' (str), 'size_bytes' (int).
Generate a PDF document from a web page.
Use ``wavexis_screenshot`` for image capture, or ``wavexis_page_pdf``
when pixel-level control over paper size and margins is required.
Side effects: launches/acquires a browser backend, navigates to ``url``
if provided, optionally evaluates ``js``; writes to ``output_path`` when
given.
Returns: JSON string with keys: 'status' ('ok'/'error'), 'base64'
(str) or 'path' (str), 'size_bytes' (int).
Scrape data from multiple URLs by evaluating a JS expression on each.
Use ``wavexis_eval`` for single-page evaluation, or ``wavexis_scrape``
when the same expression must run across many pages with pagination.
Side effects: launches/acquires a browser backend, navigates to each
URL in ``urls`` sequentially, evaluates ``expression`` in every page
context.
Returns: JSON string with keys: 'status' ('ok'/'error'), 'results'
(list[dict[str, Any]]), 'format' (str), 'count' (int), 'total' (int).
