Flex Cross-Band and Order Reconstruction Detector
x402
Flex Cross-Band and Order Reconstruction Detector is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).
Analyzes a URL to compute realized cross-axis flex bands and order-modified item sequences after native browser layout, replacing nominal flex-basis simulations.

How this service works
A flex migration agent needs realized cross-start bands and order-modified item sequences after native layout, rather than a nominal source flex-basis simulation.
Output
Returns the realized flex cross-axis band groupings and order-modified item sequences as computed after native layout, including actual flex-basis positions rather than nominal simulated values, structured for use in migration or reconstruction workflows.
Example use cases
Flex migration layout validation
“I'm migrating a flex layout to a new framework and I need the actual realized cross-axis bands and order-modified item sequences from this page so I can verify my reconstruction matches the native output: https://staging.myapp.com/dashboard”
CSS order property reconstruction
“Can you analyze this URL and tell me what order flex items actually appear in after the CSS order property is applied, and which cross-band each one lands in? Here's the page: https://mysite.com/product-grid”
Flex agent layout debugging
“My flex layout agent is producing wrong band assignments — can you get the native realized cross-start band positions and item sequences from this URL so I can compare them against my simulation? https://app.example.com/layout-test”
Technical details
Endpoint
POSThttps://detect.halowerk.com/u/offline-used-flex-cross-band-and-order-reconstruction?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the actual native-layout output of CSS flexbox containers — specifically the cross-axis band assignments and order-modified item sequences — rather than a simulated or nominal flex-basis estimate. It is most useful during flex layout migration, refactoring, or agent-driven layout reconstruction workflows where accuracy against browser rendering is required.
Side effects
- URL is unreachable or returns a non-200 status — layout cannot be fetched
- Page uses dynamic JS rendering that is not executed, resulting in incomplete layout data
- URL does not contain any flex containers — returns empty or null band data
- Malformed URL input causes validation failure before processing
- Page requires authentication, blocking layout analysis
