}List filter values
The filter vocabulary with real counts (number of flows): platform, flowIntents, uiComponents, pageType and screenPatterns. Call this before filtering search_screens or search_flows so filters are real values, not guesses. Optional query/filters narrow every count, flowIntents included.
queryfiltersGet screen
One catalog screen with its image and structure. Returns an image block (look at it for color, typography and spacing) and JSON with app, flow, platform, pageType, screenPatterns, uiComponents, keyTexts, dimensions, capturedAt and `elements` (OCR text and hotspots with normalized bbox [x0,y0,x1,y1], sorted top to bottom: use them to reproduce hierarchy, order and positions). image 'small' is ~800px wide (~1-2k tokens), 'full' 1800px. Cite the app, flow and capture date when you build from it.
imagescreenDocId必填includeElementsSearch screens by image
Find catalog screens that look like your images (base64, e.g. a screenshot of the app you are building). Then call get_screen on the matches to compare. Free plans: up to 2 images and 12 results.
limitimages必填Search screens
Search individual UI screens by description, app name or site ('paywall with annual plan first', 'Spotify', 'linear.app'). Returns metadata per screen; set includeImages to also get the top screens as images (max 4, ~1-2k tokens each). Call get_screen for the full structure of one.
limitquery必填offsetfiltersincludeImagesSearch flows
Search whole flows (ordered screen sequences) by intent, app or description. Then get_flow for the steps.
limitqueryoffsetplatformflowIntentsSearch emails
Search real product emails (welcome, receipts, onboarding, re-engagement…) by description or brand. Each result is one email with its desktop and/or mobile image; when hasHtml is true, get_email_html returns the original HTML to adapt. Needs Pro.
appIdlimitqueryoffsetflowIntentsGet email HTML
The original HTML of one email from search_emails (tables, font fallbacks, dark mode included). Adapt it to the user's brand instead of writing email HTML from scratch. Pro, or this week's free flows.
emailId必填Search apps
Find apps in the catalog by name, website or theme ('nubank', 'linear.app', 'meditation').
limitquery必填platformGet app
Metadata for one app in the catalog. Accepts an appId or a slug like 'spotify'. get_app_flows lists its flows.
appId必填Get app flows
The flows of one app (onboarding, checkout, settings…) in order, with capture date. Accepts an appId or slug. Big apps have hundreds of flows: page with offset. Then get_flow for the steps of one.
appId必填limitoffsetFind similar apps
Apps like this one, ranked from the app's own flow themes. Accepts an appId or slug.
appId必填Get flow
One flow with every step in order. Compact by default: each step has screenDocId (for get_screen), pageType, patterns, components and keyTexts. include 'elements' adds OCR/hotspot boxes per step (large: tens of thousands of tokens for a long flow); 'connections' adds step links.
flowId必填includeGet flow history
Earlier captures of the same flow (how it changed over time): capture date, screen count and up to 3 preview images each.
flowId必填Find similar screens
Screens that look like a given screen. Visual, not keyword — no quota. includeImages returns the top matches as images (max 4).
limitscreenDocId必填includeImagesList categories
The catalog's category rail for a platform, with the key list_apps filters by. Emails, games, store listings and ads have their own rails.
platformList apps
Apps in the catalog, optionally filtered by category key (from list_categories) or platform. Platform `email` lists brands with email galleries.
limitoffsetcategoryplatformList projects
The caller's projects, newest first.
无需输入参数。
Get project
One project with its screens, positions and connections.
