api record

Unchained browser automation tools. Use DDM (dom density map) for page orientation (~500 tokens), intel for extraction strategy classification, and CDP tools for interaction. Navigate and click return page layout inline — no separate DDM call needed after them.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • cdp_list_frames auth-required 3h ago

    List all iframes on the page with their frame IDs and URLs. Use this when you see iframes in DDM output and need to interact with content inside them. Returns frame indices that can be passed to ddm_frame or js_eval_frame.

  • rhythm_train auth-required never probed

    Train Rhythm on a new SPA page by recording its interactive elements. Call once per site pattern — the schema covers all pages matching the same route (e.g. train on /product/123, works on /product/456).

  • ddm auth-required never probed

    DOM Density Map — structural page layout + interactive elements. Returns ~500 tokens of page understanding. Use this FIRST on every page to orient yourself before taking any action. Common flags: --llm-2pass --cols 60 (default, best for orientation) --text (extract page text) --text --find "keyword" (find text on page) --text --max 8000 (raise text cap for long pages, default ~4000 chars) --at 694,584 (reverse lookup at pixel coordinates) --forms (detect forms) --js "expression" (execute JavaScript) When --text returns weak/empty results on JS-heavy pages (SPAs, card grids, lazy-loaded boards), switch to the intel pipeline: intel_probe first, then follow the top-ranked strategy.

  • intel_probe auth-required never probed

    Page intelligence probe — DOM fingerprint + Bayesian strategy ranking. Returns ~100 tokens. Identifies the page framework (Nuxt/Next/React), data stores, shadow DOM structure, and ranks 8 extraction strategies. Run this on first visit to any unknown SPA. After probe, follow the top-ranked strategy: js_global high → intel_stores → intel_shape/intel_find_paths → js_eval host_attrs high → intel_extract with strategy="host_attrs" react_fiber high → intel_extract with strategy="react_fiber" data_testid high → intel_extract with strategy="data_testid" innerText high → ddm --text is sufficient (no intel_extract needed)

  • ddm_frame auth-required never probed

    Run DDM inside an iframe — returns the same layout map as ddm but for the frame's document. Use after cdp_list_frames to get frame_id. frame_id can be: - An index like "0", "1" (from cdp_list_frames output) - A raw CDP frameId string DDM on the main page shows iframes as opaque 'X' blocks — ddm_frame lets you see inside: the iframe's own grid, interactive elements, and hints. Typical flow when a task requires interacting with an embedded form or widget: 1. ddm → see Iframe: stripe.com hint + X block in grid 2. cdp_list_frames → get frame index for stripe.com 3. ddm_frame("0") → see the payment form layout inside the iframe 4. js_eval_frame("0", "document.querySelector('#cardNumber').value")

  • cdp_screenshot auth-required never probed

  • intel_extract auth-required never probed

    Extract structured data using auto-selected or forced strategy. Strategies: innerText, host_attrs, js_global, react_fiber, data_testid, heading_hier, img_alt, shadow_pierce. Best for: Reddit (host_attrs), GitHub (data_testid), React SPAs (react_fiber). Site examples: Reddit → strategy="host_attrs" (web components with rich attributes) GitHub → strategy="data_testid" (data-testid annotated elements) npm/Next.js → strategy="react_fiber" (React fiber tree traversal) YouTube → use intel_stores + js_eval instead (ytInitialData global) Nuxt sites → use intel_stores + js_eval instead (__NUXT__ global) If unsure which strategy, omit strategy param to auto-select based on probe.

  • js_eval auth-required never probed

    Execute JavaScript on the page and return the result. Returns: JSON for objects/arrays, raw string for primitives. Use for: reading page data, interacting with SPA widgets, extracting structured data with querySelectorAll. Example — extract all card titles from a grid page: [...document.querySelectorAll('.card-title')].map(e => e.textContent.trim()) For JS data stores discovered via intel_stores, access them directly: JSON.stringify(window.__NUXT__.data.deals.slice(0,5)) JSON.stringify(ytInitialData.contents.twoColumnBrowseResultsRenderer)

  • js_eval_frame auth-required never probed

    Execute JavaScript inside an iframe's context. Use list_frames first to find frame IDs. frame_id can be: - An index like "0", "1" (from list_frames output) - A raw CDP frameId string This enables interaction with cross-origin iframes that can't be accessed from the main page's JavaScript context (e.g. ProtonMail signup forms, embedded payment widgets, challenge iframes). Example — read input value from first iframe: js_eval_frame(frame_id="0", expression="document.querySelector('input')?.value")

  • cdp_set_tab_alias auth-required never probed

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/fc07bbdf16e1942b/badge.svg)](https://brick.blue/agent/fc07bbdf16e1942b)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
