Query the LOCAL CACHE of every page this server has fetched and every search it has run. Check here BEFORE re-fetching or re-searching — a hit is instant and free while a fresh fetch costs 5-60s. Use query for full-text search (works for Chinese substrings and English words), get to pull a page's full cached content, stats for counts, clear to delete rows.

Click an element on a one-off page: loads url in a fresh browser context (stateless — no cookies unless passed, no shared state with other calls), waits wait_secs after load before clicking, then fires a DOM click on the first CSS-selector match. The click may trigger navigation (link, form submit) — the response url and text_after are read after that navigation lands. Returns clicked:false when the selector matches nothing. For multi-step interaction on a shared page use session_click instead.

Download a file over HTTP(S) with streaming to disk (no memory buffering), SHA-256 integrity hash, and optional resume of interrupted transfers. Filename resolution: explicit param → Content-Disposition → URL tail. Use for binaries, archives, datasets, documents - anything where the agent wants the FILE saved, not its text content read.

Execute JavaScript on a one-off page: loads url in a fresh browser context, optionally waits wait_secs for the page to settle, evaluates script (async/Promise supported) and returns {url, result}. Script-driven navigation (location.href, form submit) is drained and reflected in the returned url. Stateless — no cookies or page state shared with other calls; when the script needs prior page state or a login, use session_eval.

Fetch a webpage and return clean markdown/html/text. Use whenever the agent needs to READ any web page - blogs, docs, articles, JS-rendered SPAs, Cloudflare-protected sites. Static pages are served over plain HTTP (~100ms tier:"http"); pages that need JS get the full browser (tier:"browser"). render_tier selects auto (default) / http (pure HTTP, refuses the upgrade) / obscura (always browser).

Import login state from a real browser in one paste. The human logs into a site in their own Chrome (solving the CAPTCHA/SMS once), opens DevTools → Network, right-clicks any authenticated request → "Copy as cURL", and passes the command here. Returns a live session_id already carrying that site's cookies and sitting on the copied request's URL — the agent continues from where the human left off, no password or second login needed. Works with bash, PowerShell and cmd copy flavors.

Render a markdown document into a deterministic, self-contained HTML artifact - the document layer, so the agent never writes HTML by hand. Prose rides a plain offline shell (no fonts, no scripts); archify fenced code blocks carry typed zero-coordinate diagram JSON (sequence, workflow, architecture, dataflow, lifecycle families) and render to inline SVG via the layout engine. Same input, same bytes: the receipt carries the sha256 so determinism is verifiable. theme picks light (default) or dark; preset picks the palette family — classic (default), signal-flow, blueprint, editorial — orthogonal to theme; colors bake at generation time (presentation attributes, not CSS variables), and the receipt records both preset and theme. quality picks the composition audit profile — standard (default) or showcase, the delivery gate: the receipt's diagrams[].composition grades route crossings, ambiguous corridors, label clearance (2px standard / 4px showcase), route rhythm, and node text projected to the 930px reader width; the audit never changes the artifact bytes. Mermaid sources are the agent's job to translate, not the engine's: flowchart/graph → workflow (lanes + columns), sequenceDiagram → sequence, stateDiagram-v2 → lifecycle (bands), erDiagram/class → architecture (grid + boundaries) — read the topology and emit the matching zero-coordinate archify JSON; the engine accepts only archify JSON. A broken diagram degrades to a visible code block and lands in receipt.diagnostics; an authored route preset that cannot be honored is self-repaired to a verified semantic substitute and disclosed in receipt diagrams[].repairs - the document still renders. A fence may also carry views: [{id,label,nodes,note?}] (node ids of the active family), emitted as guided-view tabs above the diagram plus an inlined viewer script - clicking a tab lights the member nodes and the routes between them (subgraph), clicking a node lights it with its direct neighbors (ego graph), everything else dims; a view's optional note shows as a caption while it is active (the story layer). window.agxViewer in a session drives and reads the same state programmatically: {focus,view,state} as before, plus route(i,from,to) which returns and lights the shortest authored directed path between two nodes (null when unreachable, state untouched), and reach(i,id,down|up) which returns and lights the authored downstream/upstream closure ({nodes,links}); both dim the rest of the diagram. diagrams[].views in the receipt lists the tabs. With session_id the artifact is also loaded into that session (local, free) and the reply carries viewport acceptance: scroll extents measured in the live session and graded fits/tall/wide/oversized, telling the agent how to read the page back. Diagram vocabulary adapted from archify (MIT).

Search the web across Baidu/Bing/Sogou/WeChat/Google (aggregated + deduped) and optionally fetch the top results' full content. Use when the agent needs to FIND information online - replaces a search API. Supports image search returning direct image URLs. Optional engines: ["baidu"]-style filter by engine name (invalid names error with the valid list; /doctor lists them with live health). Optional time_range day/week/month/year for news freshness (engines without dated results ignore it). Response carries engine_errors explaining any engine that contributed nothing (CAPTCHA suspension, transient failure).

Click an interactive element by its index (from session_state output) inside a live browser session: scrolls it into view and fires a DOM click on the session's current page. A submit click may navigate the session — the returned url/text_after reflect the page after the action, and session state (cookies, localStorage, globals) persists for follow-up calls. Indexes come from the most recent session_state; re-list after navigation.

Click at viewport coordinates (CSS pixels) via real mouse events — pointerdown/mousedown, pointerup/mouseup, then click on whatever element is hit there. For canvas/map surfaces with no DOM element to index. click_count 2 adds dblclick.

Derive a new browser session from a live one, carrying the full login state: cookies, localStorage/sessionStorage, viewport pin, dialog policy, proxy and keepalive flags. The source session stays untouched. Use to snapshot a logged-in state before risky actions, or to run the same login in parallel tabs. Returns {session_id (new), cloned_from, url, viewport}.

Close a browser session and free its resources. For a persistent session this also drops the on-disk login snapshot - idle expiry keeps it, an explicit close does not.

Read the session's recent page console output (log/info/warn/error) as {url, total, matched, messages:[{ts_ms, level, text, url}]}, newest last. Ring buffer of 500 entries; captures output from page scripts, clicks, evals and navigation alike. Optional filters: level (exact, e.g. "error"), since_ts (epoch ms), url_contains (page URL substring), limit (most recent N matches). The fastest way to see WHY a page misbehaves: click the button, call this, read the error.

Export the session's current cookies as ["name=value", ...] for the page's URL. Use to persist a logged-in session and replay it later via session_create with cookies. Round-trips with session_create's cookies field.

Create a persistent interactive browser session for multi-step interaction - clicking, typing, scrolling, reading state across page transitions. Use when the agent must INTERACT with a page (login flows, forms, pagination, click-through) rather than read it once. Returns session_id; persists 8 min idle. With persistent:true the login state survives idle eviction and server restarts - the same session_id revives logged-in.

Inspect or flip the session's dialog policy for window.alert/confirm/prompt. Dialogs never block the page: each is auto-answered (default dismiss) and logged into session_console at level "dialog". action "list" reports {policy, prompt_text, dialogs}; "accept" makes subsequent confirm() true and prompt() return prompt_text (or the call's default argument); "dismiss" restores the default.

Drag the mouse from one viewport position to another: press at from, steps interpolated mousemove events (delay_ms apart), release at to. Moves AMarker-style drag targets and canvas selections that only track while the pointer travels.

Execute arbitrary JavaScript in a live browser session and return the result. Runs in the session's current page, so DOM mutations, globals and storage persist across calls — unlike the stateless eval tool, which loads its own throwaway page each call. Script-driven navigation moves the session's URL. JS exceptions are reported with name, line/column and stack.

Export a browser session's recorded action log. Format "bash" (default) returns a runnable curl script that replays every recorded action (navigate/click/input/scroll/eval) against a fresh session on this server — hand it to a shell or cron, zero model tokens. Format "jsonl" returns the raw action log, one JSON object per line.

Type text into an input/textarea element by its index (from session_state output).

List live browser sessions with idle age and the time left before auto-eviction. Use to discover a session to reuse instead of creating a new one; sessions expire after 8 min idle.

Navigate a browser session to a new URL.

Read the session's network request log. filter="media" extracts playback/stream URLs (m3u8/HLS, mp4, dash, flv...) actually requested by the page's player at runtime - the reliable way to get a real video link, since links embedded in page HTML are often decoys. Media elements and player iframes the engine never fetches (video/audio/source/iframe src) are merged in as candidates: via="network" entries are confirmed requests, via="dom" entries are candidates carrying their tag (iframes = kind "iframe", navigate into them to sniff). Default returns every request as compact rows (method/url/status/type/size). Navigate to the video page first, let it load, then call this.

Screenshot the session's CURRENT DOM state (mutations from clicks/evals included) as a base64 PNG via the built-in renderer. Width/height default to the session's viewport, so session_viewport + session_screenshot shows the responsive layout. Returns {url, width, height, image_base64, format}.

Scroll the page up or down by a number of viewport-heights.

Get the current page state as an indexed list of interactive elements. Returns compact text with [N] indexes for use with click/input tools.

Snapshot the session's localStorage/sessionStorage for the current origin: {url, local_storage, session_storage}. Feed it back via session_create's storage field to restore a logged-in state in a new session — the half of login state that cookies can't carry (many sites keep the session token in localStorage). Call before the session idles out.

Set the session's viewport (device emulation): scripts see innerWidth/innerHeight move, media queries like (max-width: 600px) re-evaluate, element rects re-anchor, and mobile=true flips pointer/hover matchMedia answers to coarse/none. Omitted width/height keeps the current value.

Wait until a CSS selector matches or a JS predicate turns truthy, with a timeout. The page's event loop keeps running while waiting (fetches, timers, promise chains progress), so this replaces blind sleeps for async content: navigate, session_wait for '.price-card', then click/read. Returns {matched, elapsed_ms, detail:{tag,text} or the predicate value}; errors with timeout ... naming the selector/predicate on expiry. Exactly one of selector/predicate.
